Micro H-Quadcopter by ukarmy04 Feb 25, 2013

Description

This is my second revision of the micro h-quadcopter I have been designing. I've made a few modifications in order to improve the rigidity and durability of the frame. The arms are still angled outwards at 25 degrees in order to take on loads more axially in a crash. The motor holes are designed for the Turnigy 2900KV motors and the controller board posts are designed for 50mm boards with 45mm hole spacing.


You can find a build log of this quadcopter on my website:

rctutor.org/3d-printed-micro-h-quadcopter.html

A brief overview and some flight footage of the quadcopter can be found here:

I believe someone made a remix of this frame that could be printed on smaller printers. The files should be here on Thingiverse

Well, just looked at the spec of the makerbot. It shows [9.7 x 6.0 x 6.1 in]build area. Guess it's 1" to short.

Can this be printed on a Makerbot2x? I loaded the file and it said it needed to resize for the machine.

What radio controller setup do you use?

1. Just bought my Turnigy Micro Quad..

http://hobbyking.com/hobbyking...

2. Buildt it, flew it crashed it.

3. Printed this:

Layer height: 0.2mm

Shell thickness: 0.6mm

Bottom / Top Thickness: 1mm

Fill density: 15%

Speed: 75

Time: 1h 40 minutes

4. Drilled the hole 2mm all the way on the arm mounts so i could use zipties on the motors.

5. Drilled 4 holes (3mm) under to fit the legs from the micro quad.

6. much better and stable frame. Hovers easily! Thanks

Result? Speedy mother fucker.. :)

Step 2 also included "broke" it? I see the price comparison for individual parts to the kit you mentioned is very close, within a couple of dollars. Basically you get it assembled on the frame?

Love this lil guy!

Printed at 2 outside layers, 3 top/bottom layers, and 40% infill. Ended up hitting a tree and snapped an arm. I'm re-printing now w/ 3 outside, and 60% infill. lets see what happens.

Very nice! Your build looks very clean and that 3S battery must give you a lot of power.

Got the 'copter assembled and the receiver test on the KK2 says the transmitter is talking to it. But the motors won't spin up even at full throttle. The motors do pulse at a 1s interval during receiver test so they are getting power. Is there an "engine start" button I am missing?

Follow this video series. It will help you set it up.

Very nice design! I saw KapteinKuk's print of this. You are doing a good job when someone like him says good things about your work.
I just loaded the model into MakerWare, and it seems that as provided the model is too big to fit on the MakerBot Replicator 2 bed. Is this what you would expect? I'm printing it now (using "fit to maximum size") and am going to measure how far off the size is.

ukarmy04 on Jun 20, 2013 said:

Thanks! Yeah, the overall dimensions are supposed to be ~6.3" x ~6". Right now I'm printing these on my friends Printrbot and he can fit the entire frame on the print bed. There should be a remix of this frame on thingiverse that can be split into four smaller segments and printed on smaller printers.

Might sound silly, but how did you get the props you mention on your parts page to fit on the Turnigy 1800/2900kV motors ? The props hole are really, really too small as far as I can tell.

ukarmy04 on May 28, 2013 said:

Yep that's exactly right. The prop holes are way too small for them to be tension fit without modification. I used a small file to ream out the center of the prop hole until it was just big enough to tension fit. It was pretty difficult to consistently reproduce good results, though.

shmorgan on May 16, 2013 said:

Can you provide the KK2 Settings and are you running the latest 1.5 firmware?

ukarmy04 on May 17, 2013 said:

I think I was using 1.4 when I built this quad and my settings can be found here:

I just built the frame and it looks great. Ordered the parts from HobbyKing and now the waiting begins... I used PLA with a 25% infill and it seems very strong yet lightweight.

ukarmy04 on Apr 30, 2013 said:

Good to hear. Yeah, 25% infill should be more than enough for a quadcopter this small.

guhl on Feb 26, 2013 said:

Hi,
Which print parameters (infill, solid layers, perimeters) did you use to print this model.
Thanks - Guhl

Nice! Looks much tidier then my 3D quadrocopter :-)
