I bought a tough tilt tricopter with a power pack D. I once didn't screw on the nuts of my Emax 2213-935kv motor tight enough and i lost one. I have been searching for a replacement but I can't find any. The one I lost was black and screws on counter clockwise. It would be really nice if anybody has found one of these or a compatible one somewhere like hobbyking banggood, preferably from the european warehouse. This is because I order Products from these stores quite frequently so I wouldn't have to pay somewhere around 5 euros just for shipping.
