Description

This is a drop in replacement for the stock frame of a Gaui 330xs. The original frame was cheap and flimsy, and this has proven to be rock solid, better in a crash, and has better wire management.

I've finished design on a few upgrades that make the frame much much tougher. A prop snapped today, and it fell a good ten feet and no breakage on the frame. This is a seriously high performance machine.

Recent test went like this, take it up to ~30' turn on throttle hold, it hit the grass arm first with no damage!

Also, 3 kit versions are coming, along with some minor upgrades.

Instructions

Print all parts at 40% infill
1 main section
4 arms
4 motor mounts

Necessary parts:
8 m3x10 machine screws
4 m3x22 machine screws
Servo tape
Velcro tape
A gaui 330x kit, or equivalent.

Instructions:
Print all the parts at 40% infill
Starting with one arm, place a motor in a motor mount, and bolt the combo to the arm, feeding the wires through the hole. Now place the speed controller in it's pocket, and attach the banana plugs. Repeat 3x
Now mount one arm into the main section by carefully running the wires into the main section, and through the holes in the top, then carefully run a m3x22 machine screw through the main section, GENTLY tighten. This is a tough material condition and is done so on purpose, so that it breaks in the event of a major crash because it is the quickest print.
Add velcro to the bottom, and mount all the electronics to the top with servo tape, and you're ready to fly, no soldering or modifying. Let me know how it treats you! This thing is in progress, and I will release a battery keeper.

Hi I made one.
I scaled it due to production costs. Now it is having 63,3% of size. Around 22cm of span. Now I have to put in all the stuff.
Good work though

Awesome, I'm actively developing kits for this model, when you get it working I'd love to know more about what parts you use. Please post pictures if you get a chance. 

what are the measures of the propellers?

Sorry for the delay, I use the standard Gaui 330x 8" props. Like these http://www.wowhobbies.com/G-21...

I too would be very interested in a kit. controller and all required parts aswell as some guidance about getting everything up and running assuming its not plug and play. I have never flown a quadcopter and know very little about them but if I could get into the hobby relatively cheap then i would be interested.

I really like the idea of coming up with a kit for this thing. The performance has been fantastic so far, and the mark 4 has a few small upgrades that should fix any small problems. I'll start searching for parts, and maybe we can do a kickstarter or something. Anyone who'd be interested, let me know what you'd be looking to spend, and I'll see if it is going to be feasible.

Nice! Is there a cheap kit of motors and electronics that you recommend to be used with the mk3?

No cheap one that I know of, I'm just flying with a standard gaui 330x kit, but if there's some interest, I could definitely be convinced to make some kits up.

How much does it weigh compared to the origninal molded frame?

Well the original frame is lasercut composite with metal struts, and it is ~15g heavier. But infinitely more sturdy
