No. Have checked all the possible mechanical issues and everything is good, it is more of an electrical issue . The smoothness of how the motor preforms on the control side of things.
have ordered a few esc's to see if I can take out the choppyness of the brushed motor, if that dosent work maybe a brushless motor will be smoother .
still have a few projects on the go so can use left over bits for other toys, and you can never have too many spare parts.
