Loop a rubberband around
the gear spool. Make sure
the orientation is as depict-
ed.
Experimenting with num-
bers of rubberbands,
thickness etc. might im-
prove the performance of
the vehicle.
Now loop 2 additional rubberbands after the rst one.

Adjusting the 2 screws (E) in the chassis (step 13) will
change the center distance (F) of the idler gears and the
rear wheels.
Moving the spool beams, 4 screws (G), adjusts the gear
center distance (H) of the rubberband spool and the idler
gears.
The goal is to make the gears rotate with the least amount
of friction which will make the vehicle go faster and further.
