Hoping you can assist. I've been upgrading my TT02 based on your awesome guide. As I'm getting back in to this after a 30 year hiatus the help has been very appreciated. As my 17.5 Justock motor is on the way, I decided to go with your gear recommendation of an 82t spur and 49t pinion. Both are 64p. I'm using the high speed set to attach the spur, alum Tamiya motor mount, and used the 16t holes per the guide. The issue is the mesh is def too tight. Not locked up solid tight, but nearly so. Any idea on what might be the issue? I took it out for a spin regardless (I'm dumb for an old guy) and I really love the feel with this gear combo.
I had this same problem running this gear combo and solved it by rotating the motor to the next hole going clockwise while looking at the pinion side of the motor. You should always be able to rock the gears and have just a tiny amount of play between them regardless of the pitch. To much and they strip, to little will be noisy and create drag which will create extra wear and heat up and possibly damage the motor.
