TUNING & SETUP TIPS
THESE STEPS PREPARE YOUR TRUCK FOR MAXIMUM PERFORMANCE
There are several different adjustments on
your RC10GT truck can help you adjust
steering, traction , and the handling for dif-
ferent track conditions.
CLUTCH ADJUSTMENT AND ENGAGE-
MENT
When the engine revs increase, the
clutch shoes, attached to the flywheel on
the shaft within the clutch bell, are flung
outward by centrifugal force. The shoes en-
gage the inside of the clutch bell to turn the
bell and accelerate your truck. The shorter
the clutch shoes, the higher the engine must
rev before the shoes engage (a shorter con-
tact patch contributes to this too). A clutch
shoe at stock length engages the clutch bell
more quickly than the short ones (we rec-
ommend using the stock clutch shoe length
for most conditions).
To adjust when
your clutch engages, you can change the
number of clutch shoes or alter their length.
Changing your clutch shoes mainly depends
on the track conditions.
In general, the better the traction, the
longer the shoes (quicker clutch engage-
ment, quicker acceleration).
The slicker the track, the shorter the
shoes (slower engagement), which prevents
tire spinning.
To decrease the clutch engagement, try
cutting the Teflon shoes one hole shorter
using a hobby knife. Do not trim away more
clutch than necessary, or engine damage
may occur.
For best performance, try the Associ-
ated 4 shoe clutch #7611 (requires two sets
of #7601 clutch shoes, see photo). This
clutch will allow it to accelerate harder than
a 2-shoe clutch and engages more
smoothly. The four shoe clutch shoes need
to be trimmed before using them. We rec-
ommend cutting the shoes between the sec-
ond and third hole.
Maximum cut, for slowest
engagement.
Middle.
Standard, for quickest
engagement (recommended
for most conditions).
CASTER
Caster de-
scribes the angle of
the kingpin in relation
to the vertical plane,
when looked at from
the side of the truck.
30° of caster means
the kingpin leans
rearward at the top.
30° caster blocks.
To get this:
Use this:
5° caster
#6211 front block carrier
10° caster
#6212 front block carrier
15° caster
#6213 front block carrier
20° caster
#6214 front block carrier
25° caster
#6215 front block carrier
30° caster
#6210 front block carrier
30° of caster (stock caster blocks) will give
your truck increased steering exiting cor-
ners. It will also be more stable when ac-
celerating through fast bumpy track condi-
tions. Less caster (changing to block carri-
ers with 25° of caster) will decrease the
amount of steering in the middle and exiting
corners. It will also tend to be less stable in
fast, bumpy conditions.
Recommended:
CAMBER
Describes the
angle at which the
tire and wheel rides
relative to the ground
when looked at from
the front or rear. Negative camber means
that the tire leans inward at the top. Posi-
tive camber means just the opposite. (Posi-
tive camber should never be used.) Increas-
ing negative camber (more than 3 degrees)
will decrease traction and improve stability
in bumps. Less negative camber (0 to 1 de-
grees) will have maximum amount of trac-
tion but will be less stable in bumpy condi-
tions. We suggest using between 1 and 3
degrees of negative camber at all times.
FRONT TOE-IN AND TOE-OUT
Toe-in will make your truck easier to
drive by improving stability during accelera-
tion. Toe-out will increase steering when
entering corners but will be slightly more
difficult to drive. The front toe can be ad-
justed by adjusting the steering turnbuck-
les. We suggest using 0 degree toe on your
gas truck.
REAR TOE-IN
Rear toe-in affects front and rear trac-
tion. Decreasing rear toe-in decreases rear
traction and adds steering . Increasing rear
toe-in will do the opposite. Your Team and
Factory Team kit comes with 3 deg. toe-in
in each rear arm mount and 1.5 deg. toe-in
for each rear hub carrier. The RTR comes
with 0 deg. toe-in in each rear hub carrier.
These combinations work best for almost
all track conditions.
For less rear toe-in for your Team or Fac-
tory Team kit, change to the #7365 hub car-
riers. For more toe-in for the RTR, change
to the #7367 rear hub carriers.
