Please pay attention and respect the creative commons license these files were released under. This means the files are available for personal use only. For those without a printer, all the parts are available for purchase at: http://shop.hovership.com

If others continue to disrespect the license I will no longer be sharing any future designs.

The Hovership MHQ is designed for portable FPV flying and capturing video with smaller cameras like a Mobius or GoPro. The frame is an H-Quadcopter layout with foldable arms and a vibration isolated layer for the flight controller and camera.

FPV through tight spaces: https://www.youtube.com/watch?v=a8d_lyni_Lc
First FPV flight: http://www.youtube.com/watch?v=tTA2C6hPz_w
First flight from one of my beta testers:

Motors, ESCs, Power Distrubtion boards, and Printed Kits Available: http://shop.hovership.com

Suggested motors:

Props: 5" max

ESCs: 12a, 2mm bullet connectors

Battery: 1300-1500mAh 3-cell, Zippy compact 1500mAh are nice and flat.

Frame Weight: ~133g with all hardware including motor screws

The control deck can fit a controller with a max hole spacing of 45mm. However, it is recommended to use a smaller (lighter) board. The standoffs for the top plates should ideally be 20mm or less. This will require a controller with right angle header pins.

Flight controllers that meet this criteria:

If you must use a controller with straight pins, you will need standoffs that are 30-40mm tall. With this option the battery should be mounted between the 2 top plates as to avoid the copter being too top heavy.

UPDATE 06-12-2014
Added a V2 landing gear. This version has a "rib" to strengthen the part for rough landings.

UPDATE 05-01-2014
Added a V3 arm. This has the motor mounting holes rotated so that motors with M3 screws can use the groove in the arm to run the wires straight down the arm instead of coming out the side.

UPDATE 03-08-2014
Modified both arm designs to be 4mm longer. The added length improves prop clearance from the center plates.

UPDATE 03-01-2014
Added a version 2 arm design. I noticed that with motors using the M2 bolts, the way the wires come out of the motor is not ideal. I added a groove to the arm so that the wires can run straight down the arm instead of off the side.

UPDATE 02-23-2014
I added baseplates and control decks for 6mm and 9mm vibration dampeners to allow more sourcing options for this part. See instructions for links to suggested dampeners. I have tested the fit but have not flown with these new sizes.

really cool dude u deserve more subs on u tube

Hi there, what is the weight of the frame assembled but with no electronics? Thanks

Hi there, what is the weight of the frame assembled but with no electronics? Thanks

Hi, how do the arms lock in place when open? Thanks for the great design.

what is the test one set up with and what is the average flight time I can expect running 1800mah 3s 35c batteries and 5x4 props

can i scale it to bigger one ...does it affects the performance??

Whats the biggest size we would need to be able to print? Estimated cost for an up and running kit, for someone with only a lipo charger?

Hi Hovership,

Please restock!! Can you also please give us the option to change the colors of the front and the back arms? Good for orientation.

Thank you!

Hey man great quad-copter. I recently got interested in quad-copters because of all the cool stuff you can do with them. Since this is my first quad-copter, I just have a question, which RC transmitter and receiver would work best with this? And do you or anybody whose reading this know a transmitter and receiver combo, that is cheap and would still work with this? You help would be greatly appreciated.

For simplicty, you can use Hobbyking orange transmitter and receiver. If you want to buy from US, you can buy spektrum Dx6i Transmitter and 6 channel receiver. If you think you really want the hobby and short budget, you can buy Turnigy 9XR transmitter. If you have budget, you can buy FrSky X9D transmitter and X8R combo.

Tested mine's lift force with Multistar 1704 motor, 12A afroEsc and GemFan 5030 2-blade props.
Result ~950g

Hey man! Great work! this is now on my to-print list :)

It appears ebay really doesn't care.

Dampers: Why not just use earbuds; queeze them and quickly put them through the holes and let them expand. What do you think ?

What handheld controller should I use with this?

also how much would it cost? -thanks

wow.. dudes are kickstarting a project using your hovership :/ http://3dprint.com/18822/3d-printed-quadcopter-design/

it's been taken down. yeahhh.

I have reported their kickstarter for violating my copyright and for violating the rules of prohibited items: https://www.kickstarter.com/rules/prohibited

Most of their rewards are reselling off the shelf parts which Kickstarter doesn't allow. If you want to help shut this campaign down, please also report them for selling prohibited items.

I was happy to see that taken down, I would like to say more regarding Mr Tran but I might possibly be strung up by the gonads for racial profiling.

Man I really feel bad for you guys, you spend all the time to get a nice 3d printed quad for people to download and print for themselves, and all you get are people that wana sell it acting like there are no regulations agenst it, its pathetic! If only there was a way you could prevent people from downloading the quad unless they email you with there general intent and sorta there background in the hobby to help a this problem little. Love the quad it fly's great btw!!

I reported them yesterday as well

Same here, just because you copy a BMW with your own in house molds instead of stolen ones does not make it your own new car design if you change one or two body lines.

Hi, I am wondering if is it possible to use Arduino to control this quadcopter. what would be the implications of using Arduino Uno R3?

thank you guys.
so i will be needing a controller to connect to the ESCs and another wireless controller to control the quadcopter?

The APM boards are arduino based. All of the ones i've played with are running the 2560 which is in the Arduino Mega, but these boards are much much lighter and less bulky (read, more fun and easier). The Uno won't have enough juice. I'm currently building one of these with the Rctimer Mini ArduFlyer. Tiny board, fits perfect in the micro and runs ardupilot.

There is nothing incompatible with it. Just kinda big and heavy for a mini quad.

Comments deleted.

Would anyone be able to upload these files in a .stp or .iges format? I do not have access to solidworks, but would like to modify them a bit in CREO. Thanks!

Has someone used this quad with gimbal for mobius/gopro? I like this design, but I need quad not for FPV but for filming :-) I am newby.

Unfortunately mini quads aren't powerful enough to lift the extra weight of a gimbal and still fly steady and achieve decent flight times. The minimum size prop for a quad carrying a gimbal would be around 8" like the configuration of the DJI phantom.

I have a hypothetical question. I am always buying and selling old RC equipment on eBay. If I were to build one of your quad copters, use it for many years, and then later down the road so it on eBay as a used item, would it still be against your noncommercial license? My guess is no, but I was just wondering. Like I said, this is purely hypothetical. I haven't even built one, Nor do I have immediate plans to.

You would be reselling a used personal item, not pumping out kit after kit listed for months on end on your eBay page for commercial gain, but if you read into the NC licensing it will explain it a lot better than I can, and maybe I misread something and am wrong. https://wiki.creativecommons.org/NonCommercial_interpretation

I don't mind second hand sales. It is repeated print, build, sell of the design that I am not OK with.

Aug 26, 2014 - Modified Aug 26, 2014

I recently completed a build of one of these copters to add to my array, i just wanted to share some specs, as my setup is super powerful and gives me a good 10 minutes of flight time.


Motor: Baby Beast Turnigy Multistar 2206-2150 (Super powerful, and great efficiency)
ESC's: Turnigy Plush 10 Amp 9 Gram
Battery: 4 Turnigy Nano-Tech 1300 Mah 3S 45-90C

Flight Controller: Pixhawk Autopilot with telemetry
Controller: Turnigy 9X Super Moded, with FrSky DJT Module.

With this combo of equipment i have been getting awesome results out of this copter! I really recommend the Turnigy Baby Beast motors, as they have been working wonders! Any questions about my setup just message me:) FlightFixit

You were able to fit a pixhawk? I've wanted to do this, but I wasn't sure if it would fit.

Anyone got an idea how I can easily install the vibration dampeners? The holes got printed a slightly bit smaller so I'm having a hard time installing the dampeners. One side took over half an hour but installing the other side is much harder of course. Any suggestions?

I just use something to push them through. Make sure to use something that isn't sharp. You can also use a file and make the holes a little bigger.

there is someone on rcgroups selling your frames! heres a link: http://www.rcgroups.com/forums/showthread.php?t=2232232&highlight=FPV

I am aware of this person and have contacted them several times. He thinks what he is doing is ok because he claims the frame is free when you buy his bundle. This type of behavior is making me reluctant to share any future designs.

Heres a vid to what I was talking about. http://youtu.be/5OI2Hgryv-Y

Quick question guys, I'm doing a final config before I start flying and I noticed on the null point set for the motors / ESCs on the Tau Labs wizard that one of my motors / ESCs (both hovership) sounds like it is spinning much slower than the others. I'm not sure if this is normal or not during null point config. I'll post a youtube video of what I mean.

I plan on printing this soon:) Have you thought of using Multistar 2206 Motors? they are a similar size as the other motors you have recommended, accept they are just super powerful! Great motors:) Thanks for the design!

nice job! i am using 6x4 props with sunny sky motors but arms are a bit short they hit the stand off on the frame.
Would be nice to have a little longer arms.

Have you thought about using a 5x5 prop?

Hi everyone, I have some spare motors, props, camera and tx here around, and was thinking about making this sweet mini-h on my RepRap i3, so the question is... Will 1811 2900kV motors fit on those arms? Thanks in advance!

and yes, 1811 fits good!

It would be great to have a 3 screw motor mount version.

Made the modifications, STL and SolidWorks file both posted.

MHQ Arm-V3a, Modified for 3 Bolt Motor Mounts
by cmreel

Give me the dimensions of the hole mounting pattern and I will make an arm for it.

Aug 1, 2014 - Modified Aug 2, 2014
cmreel - in reply to Hovership

on an equilateral triangle, the screw holes are 11mm apart to the centers (centers of the hole that is). having a 3 slot and 3 hole setup like the 4 slot/hold designs would be pretty perfect for other 3 screw motor mounts.
And thank you again.

Can I sell the printed parts on ebay?

No, the license is noncommercial use only.

Does anyone have any baseline PID setting i can put in my Naze32 Acro, just to start off with? Or are the default gains a good staring point anyway?


I made this and thanks for the STL files, I have already added in landing gear batt holder and others question for any builders what are your settings on a kk2.1.5 board for P and I gain? I have a small jitter that makes it difficult to FPV fly?
Printed arms 100% fill, base, 40% rectiliner and top and cam plate 100% all ABS. Created landing gear, standoffs, and special gopro holder for front. Again, great ship love the folding arms for traveling. Need to tweak settings if anyone can help?

Can you add the v3 arms and the v2 landing gear to the solidworks file? I want to arrange the layout with my fpv gear and to build a complete assembly in solidworks. Thanks

Would it be possible to use one of these http://www.radioc.co.uk/EMAX-Brushless-25A-SimonK-4-in-1-Quadcopter-ESC-p/4001.htmhttp://www.radioc.co.uk/EMAX-B... instead of 4 seperate speed controllers or is the amp rating an issue?

scrap that question - just seen the weight of it!

Small WIN!! my constant hassling, and an email to the guys at Bagggood got his....
Thanks for giving the information. I have contacted the manager and explained the situation and he said we will not sell this product anymore, I do not think we have sold any yet.
Thanks for contacting me and sorry for causing you any stress.
Please let me know if you have any further questions and I admire you for standing up for protecting your rights.
If you have other companies doing this I recommend you make a template of copyright infringement, usually a on or two page document that outlines how you own the design and the ascoiated copyright policy. And usually ask it to be removed immediately and if not removed within 7 days of this letter you will defend your copyright, something like this is quite effective.
It will look more formal and I think you will have a better response from whoever you send it to.
Thanks and I have informed the team to not take designs like this."

My hero, thank you!

I have been heard....I have emailed them directly and asked them to remove.....

Right. Don't laugh. Newbie here. I've pretty much finished the 3D printing and want to start ordering the motors etc. Am I right in thinking I need 2 clockwise and 2 counter-clockwise motors? Do you have to specify this when ordering or is it just a case of wiring them up differently?

Just wire differently. You do need to make sure you order 2 CW (clockwise) and 2 CCW (counter clockwise) props though.

OK. thanks, that is a great help.

Actually, I would recommend more then just two of each. Say 4 of each, just so when one breaks you are not down waiting for a replacement.

So I now have printed about 3 of these.... I can't for the life of me get one strong enough to fly well. All of mine have way too much flex, specifically, diagonally. I have printed in ABS with 35% Honeycomb infill, 65% honeycomb and 50% rectilinear. Then I printed one more base plate in PLA with (IIRC) 50% infill. Infact, I found the 35% honeycomb to be just as torsion-ally (diagonally) strong as the 65%, yet significantly lighter (and quicker to print).
What are you guys doing that makes this thing strong enough? How many of you are flying with true FPV systems?
My set up is:
4x RCX 1804 (Also tried 4x Maytech)
Gemfan 5030, nylon and carbonfiber props
4x Maytech SimonK ESC's
KK2.1.5 FC
3s Battery
Boscam 5.8ghs 400mw vTX (also have flown with a 200mw Immerson vTX)
Mobius w/Video out
I REALLY want to fly a good mini-h 3d printed quad, but this one seems to be disappointing me. I might just go back to my G10 and CF frames.... Its unfortunate because I love showing off my 3d printed awesomeness =D...
Any help or ideas to get this thing flyable?

I print at 75% rectilinear on the base and arms. Yes there is some flex but I don't find it to ruin the flight performance. There is a remix of my base plate that allows you to add a carbon rod down the center. I haven't tried it myself.
I am using a 500mw 5.8 tx, CCD camera and a replay xd mini all at the same time. See the new video I just posted today above.

Micro H-Quad - Stronger Base Vibe Mount 9mm and New Landing Gear

I did a post on the Banggood hovership COPY item....saying that there item was a 'NON AUTHORISED COPY'
heres the link, not sure how long it will last, before they take it down.....not sure what we can do, but you should write to them and cause them pain!!!
'NON AUTHORISED COPY, DO NOT BUY, PLEASE BUY OF DESIGNER!!!! The designer has NOT allowed this STL file from thingiverse to be COPIED!! PLEASE BUY OFF DESIGNER!!!! http://www.hovership.com/'http://www.hovership.com/'

Thank you!

I also sent all the links in a MSG to thingiverse.....explaining, that great designers will NOT like it and WILL stay away, if it keeps happening!!...I know they can't do anything, but best to keep them informed....keep up the great work!!!

I have printed and built one of these and are learning to fly now.
Is just over 8 minutes of flight time normal with a Zippy compact 1500mAh battery with RCX 1804 (2400KV) engines and 5030-props?
I have the voltage alarm set to 3.4 volts.

lipo's base voltage is 3.7 volts, if you overdischarge them to 3.4 the lipos will puff in a matter of a few weeks.

If you set your alarm a bit higher, to 3.7, your batteries will be happier. :D

the same guys also selling it on ebay

$25 more than what I sell it for and supposedly only 20% infill? That can't be good.

true, 20% infill what a joke, hopefully those people who bought from that guy don't come nagging to you about the build quality :)

It's a clone :(

this is the second time with-in a week...I have found thingiverse work on 'china' sites... both times, author did not know....time to lock this shit down guys!!

Everything to do with Bang good looks dodgy to me. I'm not surprised they copied your design.

Using the name and pictures too? That's just not right. Makes me want to log in and start a discussion on the page.

Can someone help me out with the "power wires" on the Sparky FC? I see the three wires soldered to the board but where do they connect on the other end? I know simple minded question but I am used to Spektrum and my CC3D. Thanks.

What would the total price be for this project? And would it be good for a begginer?

If you have nothing at all, it will end in the $300.

Hi, did you needed the speed controllers for the motors or not? And if yes, which type do you use? thanks ; )

Yes, you will need ESCs.
TURNIGY Plush 10A should be fine, or any ESC that can handle 10 Amp continuously

I have received those RCX motors, but the screws are too short. Can I make the arms a but thinner? Or should I try to source some larger screws? Anyone got some ideas?

I used these, thank you :).

I've just bought longer screw, and it goes well

Which size vibration mounts/frame are recommended to go for? Printing the M3 arms at the moment but no idea which frame bits to print!

Can the new longer arms fit 6" Props?

Wish I could find something like this to print, but just in a hex version

I'm currently designing one. Should be out in a week or 2

Minus the cost of printing, how much does this cost to make?

Has anyone built this who has absolutely no experience? Any tips/pointers for a newbie trying to take on a project like this?

it was my first and I have minimal RC Flying experience. And it is AMAZING ! I built one too for an experienced RC Flyer. He ends up flies this even more than his DJI 450 one !. High recommend for your first. So small that's hard to crash... But be carefull can go fast and far too :) Proceed with no limit is my advice to you.

Where did you source all of your parts? Do you know anywhere in Canada so I can avoid high shipping costs?

Well that's where google is your friend... I live in Switzerland and shipping costs are huge. Compare wisely... managed to keep this around 200 USD sourcing from MyRCMart and Hobbiking (eventhough they are VERY long..). This excludes the Radio, the HD cam and some basic for newbies like a lipo charger...
My setup - and very cool result - (but author gave many alternatives as well )
2 RCX 1804 (2400KV R) Micro Outrunner Brushless Motor (Clockwise) - Thrust 250g
2 RCX 1804 (2400KV) Micro Outrunner Brushless Motor (Anti-Clockwise)
4 RCX 10A ESC Brushless Motor Speed Controller (G Series / Programed for Multicopter - SimonK Firmware)
2 5x3" EPP5030 Counter Rotating Propellers (GM Series / Pair / Carbon Fiber)
1 Battery Lipo 2200
25C ==> You get 13-15mn of flight
1 DJI Naza M lite Flight Controller ==> KK2.1 would do equally...
Good luck

Thanks for the tips!

what blades did you use

Sorry, I see that you were referring to the 2204-28 motors from cobra. I wonder if the 2204-32's would work for a slower flying quad? Maybe better to learn on?

From the prop data, it seems like it would be ok with a 5" prop. http://www.cobramotorsusa.com/motors/Cobra_2204-32_Specs.htmhttp://www.cobramotorsusa.com/...

You list the cobra 2204 motor with 2300kv. I only see a 2203 cobra with 2300kv.

Hi, I think it's better to make dampers slightly angled, like it's done here:

MHQ Omni Vibe 7mm

What is the benefit, to print easier?

I just thought I'd add something for anyone that had a problem finding the standoffs like I did.
I had all the metric screws, nuts, etc. but couldn't find a the black M3x20mm standoffs that are used when you buy the kit or hardware kit except from a couple of chinese places.
Decided to try and print my own and turned out really well.
You can get them (http://www.thingiverse.com/thing:335435)http://www.thingiverse.com/thi...
And I'm not trying to take away from Hoverships business or awesome design at all, just trying to help people out who cant find these.
I weighed the standoffs, and my scale only has 1g increments. I weighed 1 of the standoffs and it came out to 0g. All 6 of them weighed in at 4g. I am not sure what the aluminum ones weighed but these seem really light to me.

M3x20 Standoff

Hi everyone,
is anyone using a FLIP and the RCX Motors and Blue ICE ERC's from http://readytflyquads.comreadytflyquads.com with this frame and can share MultiWii settings. I finished my build and while I can get in the air the thing dancing around quite a bit. I am also wondering if this combo would create enough drag to lift a camera as I am under the impression is has a hard time to lift without one already. I really love the design but it's sort of unflyable at the moment for me as it reacts quite heavily to minor stick movements too.
Thanks for any feedback

Do you have auto-level on? Have you set some expo on your aileron and elevator radio channels?
Also, I have heard the RCX motors have issues with certain versions of the simonk firmware: http://forums.openpilot.org/topic/35064-zmr-1804-motors-blueseries-esc-12a-trouble/http://forums.openpilot.org/to...

I have to admit that I am sort of stupid because I ended up mounting props upside down. Noob.., I have cut the default values of P for Roll and Pich to 1.6 from the 3.3 default values as the frame was oscillating quite an bit but I have not done more. The quad is flying quite ok in acro and angle (a.k.a auto-level) mode. As soon as I have reasonable values that work I will post them here.
p.s. how is the power distribution board coming along? I can't wait to get my hands on it.

Adding to the chorus of 'just finished my build' posts. Very happy with the quad, thank you for sharing the design. I've posted a first flight video here: https://vimeo.com/95013574https://vimeo.com/95013574 and a full build log/blog post here: http://www.jiggywatts.com/technology/3d-printing/hovership-a-quadrotor-experiment/http://www.jiggywatts.com/tech...

Just made one and did a first flight with it. Sharing the video as I'm really happy with this... Amazing work from you and thanks for sharing, really.
Saw your comment on the RCX 1804 which I am using and I have no issues to report. I did rework the arms thickness under the motor base to match the standard shipped motor screws length (could not find the screws long enough...). If anyone interested let me know. Used the Naza M lite as flight controller and just perfect.

what gains settings did you put in the Naza ?

May I ask what you are using to print these kits?

I see you have Turnigy 9XR and I was wondering what module/receiver are you using with it?

Hawkeye OpenLRS on the 9xr, DTFUHF 6ch on the copters

Do you know if Hobbyking's OrangeRX Open LRS is similar or something totally different?

Similar but from what I know the Hawkeye, particularly from DTFUHF has better filtering and other improvements. http://www.rcgroups.com/forums/showthread.php?t=2005885http://www.rcgroups.com/forums...

Hi. I just noticed that Hawkeye doesn't come with antenna. Where did you get yours?

I use the Diamond SRH771, got mine from http://readymaderc.comreadymaderc.com

No usually you want a rx antenna that has a right angle connector on it. You also want them thin and light. These are commonly referred to as a "whisker" or "sander style" antenna.

Anyone flying their MHQ with a FS-TH9X?

Any tips on supports? I have tried about 20 times to print the base and have failed each time. Supports with and without a raft, no supports and I just can't seem to print it! I am using RepG and a flashforge printer.

I accidentally printed one base without supports, it came out surprisingly ok (the 7mm model)! I was printing inside out. I print on hairspray with glass and the plate was 110C. Sticks well so no raft is needed. I'm also using a FF printer but I'm using Simplify3D. The supports in S3D are really nice. I haven't printed supports in RepG but I never had good success with supports in Slic3r.

Is it possible to use the Naze32 flight controller as opposed to the acro naze? They both appear to be 36x36mm


I'm new to quad-copters, can someone point me to a list of all the electrical parts I will need? Thanks :)

Printing mine now! I plan to use a flip ez flight controller with mine. Just ordered my hardware kit from you (way easier than searching through HK to find what I need) wish I had remembered to order props! Cannot wait to finish the build. I can't afford these little CF and G10 quads that people are charging $120 for just the frame!
I love how you have a website where you sell them but offer up the files here on thingiverse free of charge for those of us fortunate enough to own a 3D printer. Great design! will post pics when it is all done!

What controller are you using? And what flight controller are you using? Would it be possible to just give us a spec sheet of the exact parts (electronics) you are using on yours? Thanks!

Hobbyking just released a new KK2.1 hard case flight controller that has right angle pins. It moves the LCD to an external programmer as well. The board will be even lighter if you remove the hard case. I have one on order and will be testing it with this frame.

Hey gang, need to ask for a favor: I would like to ask for pictures about how people are attaching the ESC and organizing the wires. I am curious to see how people are doing that, I havent found a definitive way to properly install then.

I added a picture of my ESC layout in my makehttp://www.thingiverse.com/mak...

Hovership MHQ - Foldable Mini H-Quadcopter

I solder the wires together and add heatshrink or liquid electric tape over the exposed wire. However, I am waiting on prototypes of a small power distribution board for use with this frame. The ESCs, I just use some cable ties to hold them down to the base part.

I just received and assembled the kit…I have a pixhawk from 3drobotics do you think it will work? That and the ublox compass module are much heavier than the boards that you are recommending. I went with the T-motors you suggested. Thanks in advance!

If that is all you are going to fly on it, yes it should be fine. I wouldn't recommend that big of a controller if you are going to add a camera or fpv gear.

Started the print job going. Base and Arms first, 3h11m and I'm 50% in. So thats a 7h print job before I can print the other bits.

What layer height are you using? I typically go with .2-.3mm height and use a 0.5mm nozzle. High resolution isn't needed with these parts. I am able to print a complete frame in about 2.5 hours.

I used .2mm layer height and a 0.4mm nozzle. The print is all done, it took three runs to do the base, the two plates and the rotor arms and landing gear.
I've a question for you re the rotor arms. Would you be willing to create an STL for 3-hole AX-1806N-2500 motors from HobbyKing? See: http://www.hobbyking.com/hobbyking/store/uh_viewItem.asp?idProduct=29672http://www.hobbyking.com/hobby...
The hole centres are 1.6cm apart. Perhaps the triangulated holes could be incorporated into the original design? I have no particularly good CAD skills to re-do your design.
These I've used well in another micro-quad. The other motors you linked to are not in stock anywhere I could find, so the AX-1806N are my next choice based on my own experience and other in a forum I'm in, they're pretty strong.

Hey thanks for sharing this. Are you using one of the flip or acronaze boards? if so do you mind sharing your PID's?

Currently the acro naze. Still fine tuning this board.

If anyone is looking for the SunnySky x2204 kv2300 motors, you can find some here (for now) http://www.multirotorsuperstore.com/motors/motors-sunnysky.htmlhttp://www.multirotorsuperstor...
No affiliation. I just ordered some.

They always sell out so fast. -_-

Ya, when I checked they had over 50 in stock. Were sold out 12 hours later!

Super design and amazing quad. Printing it right now. Thanks for sharing !

Just a heads up, if you buy the hardware and 3D printed parts separately on http://hovership.comhovership.com it's actually a couple bucks cheaper than altogether. Just thought that was weird.

Actually it is the same price. The hardware kit doesn't include screws for the motors.
$16 hardware kit
$2 motor screws
$22 printed parts
= $40 same as the full kit.

Oh I wasn't aware, thanks!

Question for those of you who have successfully built and flew this amazing little beast - did you use a ESC Power Breakout Cable? If so which one would you recommend (I am not sure of the correct size)? Sorry for the novice question. Thanks

I currently solder all the wires together and put heatshrink over them. However, I am working on a small power distribution board for this frame and will be selling it in my shop.

Excellent idea on the power distribution board. I was actually thinking of replacing the control deck with a PCB with power distribution and such, but I think a PCB of that size could be a little expensive in small batches.

Sounds great. I'd be happy to support your shop again once you have it posted.

For mine I removed the power cables from my ESCs, and soldered on longer cables which I then bundled up into an XT60 plug and added heatshrink and mesh. Hope that helps.

Just a heads up for everyone - The SunnySky motors are in stock now at http://witespyquad.gostorego.com/motors/sunnysky-x2204-2300kv.htmlhttp://witespyquad.gostorego.c...

Jump on them before they are gone again lol

is anyone else having issues with the deck portions on export slicing?

I think you need to fix the exported stl file using the latest slic3r "Repair STL file..." option before it can slice properly

Is there a reason the stl's are orientated the way they are?

That's how they export out of solidworks. I have been looking for a way to fix it.

You can insert Reference Geometry -> Coordinate System.... with X Y Z oriented in the way you want it to lie on the print bed and then Save As STL file with option selected Coordinate System you have just created.

Perfect! Replacing all the STLs now.

alternatively you can also create an assembly and mate to the front plane.

Nicely done. Love it. John

Hovership Is there a site that You could find everything you need for the copter except the 3d printed parts? I just want links to everything you suggest for getting this thing in the air Just a line of links. I dont have any equipment but a 3d printer so I dont have anything. handheld Controller/radio, controller, Motors, props, batteries. you kinda give us a good Idea of what to get but I want to know What you hands down recommend for me to buy to get this in the air.

I am working on a list, will be posting an extensive shopping list on http://hovership.comhovership.com

Has anyone had any luck finding any of the suggested motors IN-STOCK for shipping in the US? I have looked everywhere it seems and can't seem to find them. ugh How am I to get this amazing little beast flying if I can't get the motors on them :-)

Thanks, I'll keep watching them and have signed up for stock notification's as well. I'm looking forward to getting mine in the air.

Is there such thing as a website that doesn't have everything out of stock? Really hard to find any of the correct parts.

I feel your pain. This size of copter has become really popular recently and parts are hard to find.

Do you think you will ever sell a electronics kit for this copter?

Eventually, starting to talk to some manufacturers now.

I found 5 of these for sale. Are they the same ones as you suggested? SUNNYSKY X2204 1480KV Outrunner Brushless Motor.

Also would this ESC work?http://www.ebay.com/itm/New-1-Afro-ESC-12-Amp-Multi-rotor-Speed-Controller-SimonK-quadcopter-UBEC-12a-/141238355565?pt=Radio_Control_Parts_Accessories&hash=item20e276466dhttp://www.ebay.com/itm/New-1-...

And finally what would be your most recommended Controller?

No, those are the wrong KV motors. You want these and I am told they will be back in stock soon: http://www.multirotorsuperstore.com/motors/70/sunnysky-x2204-2300kv-brushless-motor.htmlhttp://www.multirotorsuperstor...

Yes, those ESCs are good. The new version comes with thinner wires and 2mm connectors which is good for this size quad: http://www.hobbyking.com/hobbyking/store/__53764__Afro_ESC_12Amp_Lite_Multi_rotor_Motor_Speed_Controller_SimonK_Firmware_Version_II.htmlhttp://www.hobbyking.com/hobby...

Flight controller, if you are on a budget go with the Naze 32 or Flip controllers. Both run multiwii code.

Printing AWS, just wondering about the lift capacity, i guess not all of the gopro models are good to go or will a Hero 3+ Black at 73 g work?

Don't go with the multistar motors if you want to carry FPV gear and a GoPro. They aren't very powerful. You can lift a gopro with the Sunnysky and maybe RCX motors.

Can confirm the RCX motors can lift a mobius so can probably lift a gopro too

I am using a 9mm dampeners at the moment. The only ones I have at the moment. Are there any benefits of using larger or smaller dampeners? I would think larger dampeners would remove vibrations more?

The bigger dampeners will give you more height space for the ESCs. Bigger will mean you have to use softer dampeners because of the added material. The softer ones tend to pull out easily. The small grey ones I use are a medium hardness and stay in the frame quite well.

Will printing in printing in nylon be a serieous option for printing 3d printable copters?

I have some nylon on order to test this frame with. From what I understand, nylon isn't as stiff. So most likely the design has to be beefed up to use more material and thus more weight.

I've gone through many roll of nylon and generally speaking you are correct about it not being as still. Though that doesn't necessarily mean it will need to weigh more. It just needs to be designed differently. Maybe thicker with a lower fill percentage. Taulman has some new "Bridge" nylon which is pretty cool stuff.

Yep, got the bridge coming in the mail. Will be seeing how it compares.

I just ordered some Taulman 618 yesterday. I was hoping to try it for this as well. Let us know how it works out when whoever gets it printed first in nylon.

Hey, will you sell the non printed parts as a kit eventually in your web?

The hardware for the frame? If so, I already do: http://shop.hovership.com/frame-spare-parts/http://shop.hovership.com/fram...
If you are referring to motors, escs, props... eventually, yes.

estimated project cost? I think this would be a useful feature on thingiverse

Depends, you already have a radio control set? Batteries/charger? Video gear?

If we have nothing and are totally new to this. I am also interested in this question.

I plan to do a blog post about this soon on http://hovership.comhovership.com - I have an older post on there about getting together a quadcopter kit but I need to create a new list tailored to this frame.

How many cubic inches of material does this use?

A full set's volume is about 105 cubic centimeters. My slicing software estimates about 4085 cm of filament.

I have no experience with drones, and I'm looking for a simpler build to start myself with. Would this be a good choice?

For learning to build, yes it is a good small size. But if you want to just learn to fly a quad. Look at getting a cheap ($40) quad toy to practice on first.

Do you have an estimate for the cost for the entire BOM?

If you fly this near anyone or near property it is a threat to safety and property. Be advised to not use this near where people live.

Thank you very much for sharing!!
Very nice work!

Thank you and you're welcome!

I have a controller board with vertical connections so my top plate is a bit to high for the battery. Instead of placing the battery on the controller deck i'm planing to place it underneath, between the landing gear. The Zippy compacts 1500 are only 14 mm thick so this should work. Anyone tried this?

It will be too long to fit between the landing gears. I have been considering revising the base plate so that the landing gear can be further apart. The 1300 batteries fit but are closer to the ground.

Link to your video tx please?

Thanks a bunch that helped, hopefully I will test print tonight. Keep leaving the files at work.

What kinda flight time do you get on this with a 1500 mAh LiPo?

I may have another motor source, once I get them in I will let you know what I think.

I get about 8-9 min with all the FPV gear and flying around fast like in the demo video above.

awesome, I got the modified top plate printed and it worked great. The bottom deck worked but I made another change for ease of printing. Once I get it printed I will post the modified files. Thanks again for the iges file. I hope to have all the parts printed and test fit by this weekend.

You wouldn't by chance be able to add a stp or iges file set could you? I work in an older version of solidworks so I can't open those files as I would prefer. But I should be able to make the edit I need if I had a different format. I need to split the deck into 2 pieces to get it on my print bed. I was thinking an overlapping section to either glue or bolt together. Its just a bit too big to fit on my printer.


This looks fantastic! 2 questions, would this be able to be printed on Up Plus/Afinia H with 140mm print bed? Also would a KK2.0 board fit on this?

You will need at least a 200mm bed. A KK2 will fit the mounting holes but it is a heavy board and it is recommended to use a controller with righ angle header pins.

Unfortunately it looks like someone does not know how to read the "non commercial" license. Also did not link back to this page.


Congratulations. Neat, simple, working. Magical :-))

Took mine out camping and got some nice shots of it in the air as well as some video testing altitude hold


Does this have the power to lift a GoPro?

Yeah, I tested that out with a 1800 mAh battery and it flew fine. Didn't get any video though.

Came by way of DIY Drones... looks like a sweet design, I'll be downloading it and trying it out. Thanks for uploading!

What sort of flight time you can get with your setup and your AUW? Really interested to build one but already have too many quads!

I am getting about 9 min flights with all my fpv gear and a 1500mah lipo. This is when constantly racing around as well.

second this request! is the 1300-1500 the cutoff weight, do you think 2200 3s would be too heavy and have no benefits?

3rdeyepro was nice enough to make me one of these. I have to say so far it flies really well. Got it doing a little return to home this weekend.


Got some more flying done with mine and video from onboard camera.

This is testing some altitude control code: https://vimeo.com/88439963https://vimeo.com/88439963

And this was out camping. It was great since I could just throw it in my backpack: https://vimeo.com/88023020https://vimeo.com/88023020

i would also want to know can i sell this but only charging material cost?

That is fine

beautiful quad! I had someone contact me asking me how much I would charge to print this for them. I do not want to profit from your design. If I do print it for him I would only be charging for print time and material plus shipping as well as a donation for you. Of course I would like your permission before I even print this. If this is ok with you let me know, If you would rather print it for this person I will be happy to put you in touch with him! Let me know and thanks!

I will be selling kits printed by me soon, until then it is ok for you to print one for someone else and charge for materials. There is only so much you could charge on top of all the materials before you are getting near the cost of the more expensive, similar frames. Which defeats the idea behind this design.

This quad looks great. Will a naza flight controller fit? Maybe with larger stand-offs?

Should fit fine

Beautiful design ! Did you try to print plastic washers to ?

Print Deck Cam oriented 45 degrees and it works!!!

Hi, thanks for the tips , after careful adjustment, I manage to print Deck Cam plate 45 degree . thanks !

just printed al;l parts accept deck-cam plate, seems longer than 200mm, my print bed only 200mm max ;-( anyone who shorten it a bit please share the STL thanks !

I can do it in a few days, out of town right now

Do you use the Mobius camera to record and for FPV?

To record, using a nano CMOS can for live view

about how much does the chassis weigh before adding electrics to it?

Wonder how much it weigh using shapeways white strong flexible any ideas?

Not sure, but I can bet it will be expensive to print through them

Heey, i am using slic3r and i am not able to turn the deck over the x axis so i cant make a gcode from it ?
what are the dimention's of the biggest part im using a Makibox

Sorry I am out of town for a week and am unable to modify any files. Maybe try an app like this to rotate it http://replicat.orghttp://replicat.org

Hello, Can you please release the CAD files? I would like to modify the design a bit.



This is a beautiful design!
Do you have any flight videos of it?

Please share any changes you make

Not yet, still getting it tuned well. Just been doing a lot of testing. Good news is the footage is jello free!

Hello, Can you please release the CAD files? I would like to modify the design a bit.


Solidworks OK?

Yes, that is fine.


Please share any changes you make.


I have 3S 2200mAh batteries, will them be too heavy?

I tested mine with a Turnigy 3S 2200mAh battery - it flies pretty well, but I only tried it without FPV gear/camera.

Might be ok with no FPV gear or camera

I flew mine in exactly that configuration since I was testing nav. No problems and good flight time.
