Mini brushed quad copter.

I designed this with the idea of learning how to fly these things from the comfort of my living room.

It is slightly on the heavy side at just under 60 gramms with a 400mah 1S lipo, but with the prop shield it can handle some impressive collisions and crashes so is actually quite robust. I designed it to print as much as possible in the X-Y plane for optimum strength.

Parts list:

4 x 8.5mm brushed motors (2xCW, 2xCCW)
4 x 55mm props (2xCW, 2xCCW)
1 x HappyModel SP Racing F3 EVO Brush
