I finished building my G pig but it won't fly! It weighs about 1.1 kg with no battery (recommended is 1kg), has 1000kv motors spinning a 10x45 prop and I think the motors are the problem but I don't know for sure. When I throttle up slowly both motors spin fine but I don't think they reach their max rpm. On the other hand when I throttle up more quickly one motor spins really fast while the other does nothing. Another thing, the one that does nothing spins freely when I turn it with my hand but the other has more friction, not by a huge amount though. Another-nother thing the motor which has more friction's bell comes out a bit, by about a mil. My friend says the my G pig could just be to heavy, I have put it on a diet, removed some wheels and cut off some extra glue (not that there was very much) but it still wont take off. It wants to, its very close to taking off, but it doesn't fly. Does anyone have any advice?
