of the most important areas of R/C is making sure
you have your gear mesh set properly. It is one
of the most difficult items for those new to R/C
to understand and to get properly set. Every time
the motor is removed for servicing we see even
experienced racers struggle to get the gear mesh
the gear mesh is too loose, it can cause stripped
gears. To tight of a mesh can cause poor performance,
gears to wear out, excessive bushing and bearing
wear, motor overheating and in some cases motor
failure. This is why getting it set properly is
important. Follow these simple steps to get your
gear mesh set just right.
the motor in your car or truck.
a small piece of notebook paper between the spur
and pinion gear, position the motor so the pinion
and spur gears pinch the paper snug and then tighten
the motor mount screws.
the paper out from between the gears (with the
wheels off the ground). The paper should pull
from the gears without tearing. If it tears, the
mesh is too tight and you need to try it again.
a close look at the clearance between the pinion
and spur gears. The gears should just barely have
clearance between them but yet not be too loose
as to allow the gears to strip. After you use
the "paper" method a few times and see
what the proper clearance is between the gears,
you will be able to adjust the gear mesh without
using the paper.
luck and happy racing,
