Just upgraded my twin 550s to a single 775. Little more torque, but main reasoning behind it was i went through multiple sets of 550s. Anyways theres almost a constant knocking sound from motor. any ideas what this could be?
It might be your diff. Is it coming from the front or rear? Have you check for little twigs or branches? How's your gear mesh?
Oh I'm sorry, I didn't see you said from the motor.
yea its all good thanks for the reply. Gear mesh is good, not sure what it is.
Did you notice any difference in the top end speed?
Did you change the gearing at all?
running 18/68. Top end seemed to die down a bit. was using 19/68 with the twin 550s
Move the motor away from the spur gear and give it some throttle to see if it really is the motor making the noise. It's very strange for an electric motor to make a noise like that. Much more likely to be a diff, those are usually make that sort of noise on a revo.
Using while stupid may cause serious injury.
