Open source 450 rc helicopter

This is an open source (almost fully) printable helicopter. It should be compatible with any of trex-450 rotor heads. DFC rotor head included with this model is fully printable, but it needs to be tested yet. If you would like to print and fly it, consider using DFC swashplate to avoid damage caused by blade holder linkage coming off the swashplate. Direct drive fixed pitch tail rotor is used to reduce mechanical complexity of the frame. I printed everything except a motor frame (which had been printed in ABS so it would not melt) in PLA, and it seems rigid enough. THPA20S 90w 2800kv motor fitted with a 5x5 propeller is used for a tail rotor, you can change it to any similar one.

To assemble this, you would need m3 and m4 hardware of various sizes, aluminum square pipe 400x10x10x1mm, aluminum round pipe 8x1mm, 4x8x3mm bearings for the head, 5х11х5 bearings for main rotor shaft, trex450 swashplate, main gear assembly and a 5mm main rotor shaft.
