With each build I learn something. Fendered cars need tire clearance for fenders. I thought I could slam this car nice and low. Then came the F1 learning curve. This is the first Shadow DN1 build thread so I had little to dig up on the subject.
The crown gear is the hurdle to lowering the rear of this car. I already know that the motor likes 3/1 gear ratio from the F1 cars we race. 9×27 is typical of the F1 gears. Anything outside 3 to 1 is an experiment. However the 9×27 tooth gear is much larger than an 8×24 combination. I went with a 9×28 to experiment. I had to raise the back of the body to accommodate the large crown gear.
The front body height is limited by the tire diameter. I left too much meat on the front tires to lower the front more than it is. The car has body float. But bearings almost touch the inside of the body.
If I were to build this chassis again. I would shave the front tires down to 16mm or 17mm diameter and run 8×24 or 8×25 gear ratio. I might actually make a new chassis for this car after all the classes are filled (getting close :wacko: ).
It runs, but needs a number and decorations.
The wire from the motor to the guide did not fit over the front axle because the body is too close. Crossing the wires at the guide allows the guide to move freely with the wire under the axle, and out of the way of the body post. Pinching wires under body posts shorts out the car. I figured that out the hard way.
This is a simple and fun car to make. The hardest part will be choosing where to put stripes. I look forward to racing a Shadow DN1 for the first time! Thanks for looking. Ken
