Frame for UDI U816 Quadcopter by CarryTheWhat Nov 8, 2012

Description

This is an add-on to the greatest helicopter toy I've ever played with: the UDI U816.

You can buy the copter on Amazon prime for $60:
amazon.com/UDI-Axis-Stablized-Quadcopter-Helicopter/dp/B0095BXACK/ref=sr_1_1?ie=UTF8&qid=1359084783&sr=8-1&keywords=udi+u816

Or if you buy more direct ~$40: banggood.com/Wholesale-Udi-U816-2_4g-4ch-4-axis-Mini-Rc-Remote-Control-Ufo-360-Eversion-Helicopter-p-48619.html

And to support the development of new designs, I have started selling the completed thing on etsy and Tindie:
etsy.com/shop/CarryTheWhat?
tindie.com/shops/CarryTheWhat/rc-quad-copter-3d-printed-frame/

It comes with a 2.4ghz radio transmitter, and a decent one at that. 2 batteries, extra blades... but a flimsy plastic circuit cover.

The quadcopter itself is about 30g, and about 7 inches from tip to tip.

The printed frame in it's current form is about 15g -- the quadcopter has plenty of surplus thrust to carry it. The extra inertia is actually pretty useful for keeping control.

I was unable, however, to successfully print any of the blades that have been uploaded...

That's odd! What SCAD are you using? I used OpenSCAD version 2012.02.28 -- so, that might be out of date at this point..

Are you able to use the STL files? Would you like my generated gcode?

Instructions

Print the full frame, if your build space is large enough.

Neither of my printers could fit, so I split it into quadrants.

Print 4 of the quadrants separately, no raft or support necessary.

Then flip them upside down and align the four quadrants together. Add acetone along the edges that come together. I used a pipet to dispense.

To attach to your helicopter, remove the original plastic UFO decal. There are 4 slots in the frame which will fit snuggly over the crossbars extending out to the motors.

You will probably have to re-trim (for some reason, especially about the yaw) because of minor changes to the balance.

Scad crashes when I try to open your scad file. Any ideas?

Does not appear to be manifold in slic3r 0.8.4... and netfabb is down for maintenance :(
Oh odd! It could be several reasons... I only sliced it in delta micro factory's up! software so far. I will try it in Skeingforge later -- But I will also upload the openscad in case it is helpful.
I had to go buy one of those quadcopters. Its the cheapest looks to be best flying that ive ever seen. I will most likely be printing one of your frames when it comes  glow in the dark abs mite look cool. Thanks for sharing this.. 
 Great, let me know how it goes! I meant 'best' in the class of 'toy helicopters' that it's in... but I have no real experience flying the super nice RC helis -- just sort of the sub $100 range.
Nice!
greatThis would also be a great idea for my printable quadrocopter :-)
