Hello Dazee,

I'm happy to hear of your success! Congrats on making an aluminum chassis! It looks great!

I'm still doing well with these, and often win a race or two within my club.

I usually run a spacer under the motor and tilt it slightly so as to help provide more space between the rear of the chassis, and the track.

This chassis has a brass spacer under the back of the motor to bring the slim line motor shaft in line with the axle.
   

The chassis below is designed for a larger S-can motor. It has a brass spacer under the front of the motor to properly line the pinion up with the crown. The spacer is hidden by the epoxy, but it's there.
   

I try and keep the chassis height 2mm off the track front and back no matter the motor choice, or tire diameter.

Cheers,
Ken
