These are some basic set up
notes for a
"First Time" Drag Racer
Basic Drag Car Set Up:
Gearing: put on a spur gear, and then
put a pinion gear on the motor. Next run the car and then go up or down from
there with the pinion gear size to get the E.T. , and speed, that you are
looking for in the bracket classes.
Typically keep going up with the pinion gear
size until your E.T. drops works for the head to head classes.
Remember that your rear tire diameter plays
an important role in the final roll out of the car!
We use a motor spacer between the motor
plate and the motor so that the pinion gear is easier to align with the spur
gear without being at the far end of the armature shaft.
Before your first pass roll your drag car
on a flat, level surface without any gear mesh to test your radio setup.It
should roll on a straight line, if not,adjust steering until it rolls straight,
Your car should be in a "ready to run" condition with all electronics and body
mounted..
Use 1 line of 1/8 wide traction compound
of your choice around the rear tires, and then rub it into the tire across the
face. We completely clean all traction compound out of the tires after a pass
with lighter fluid and then start over again. Keep notes! You should have a
little tire spin. Change the number of lines or compounds until your
traction is correct for the track conditions.
We run a tire diameter of 2.25 inched to
2.45. We would true them once per day minimum.
Make a few short passes to check the
weight distribution, your batteries are critical to the setup of the Drag
Car.

GOOD LUCK!
