Hi, my RC is having problems with the motor. It's the stock motor for evader st. It's PHOTON SPEED MOTOR (20 turn, single wind) from Duratrax. I replaced all the bearings. It doesn't move at all, nothing spins. I have gotten tired of poking at it, trying to figure it out. I don't know if I should buy a new one and or upgrade and if I did what would be the best motor to upgrade to? Thanks for the hell!
