      Hopefully this will get finished in time for the next race. This car was painted at the last paint workshop. Then stripped and repainted. Second time was the charm. Quite the challenge to fit an aluminum chassis under this body.

      The body had to be sanded to get the chassis to fit. Using a nail-file, it took about 20 minutes. But it also prevented removing too much material too fast. That kept the tolerance close. I thought I would have to give it more clearance for body-float. But the body lip at the bottom lines up with the pivot-point on the post, so it never touches. Luck was on my side.

      It took a small piece of brass to align the pinion with the crown. The motor shaft does not go through the pinion. The bearing takes all the side-load of the low power motor.

      It took a little extra chassis trimming to get the guide to fit under the front axle and still pivot. Almost half the bearing support had to be removed. The guide screw almost touches the axle. Tight fit.

      A little extra material also had to be removed from the back of the chassis to fit the body.

      The solid body posts were removed in favor of #227 Evergreen hollow tube and 4-40 brass inserts. The empty body weighed 8-grams before adding the rest of the parts from the kit. The car now weighs 68-grams in total. Thanks for looking. Ken

      I forgot to to say… The wheelbase is a bit hard to figure out with such a large opening for the front axle. After examining what felt like a thousand pics on Google images. I came to the conclusion that the wheelbase for my 1936 Type C would work out to be approximately 87.75mm.
