Just a little about what I have discovered with sidewinders using CAD. I keep the motor to rear axle distance at 0.445 when using the 18mm spur gear and the 6.5mm Pinion gear. And then the hole for the motor is 0.015 higher than the axle. Then I use the small 3/32 x 3/16 PM bushings since when I used the 1/8 brass tubing, the tubing would contact the motor. Maybe it is the plastic chassis but the gears mesh super smooth and it is really quite.
But really you have a super nice build going there. I can't wait to see how you mount the body onto the chassis.
