Changes to wheelbase can aect the overall handling of your vehicle, since it adjusts the distribution
of weight on the wheels as well as the angle of the driveshafts. Shortening the wheelbase at the
rear will give you more steering into a turn and o power, less steering out of a turn and on power.
Lengthening the wheelbase at the rear will yield the opposite results.
Shortening the wheelbase in the front will land jumps a little better and lengthening it will be better
through small bumps. In general a longer wheelbase is better on open and/or bumpy tracks and a
shorter wheelbase is better on tighter technical tracks.
This chart shows the recommended starting ratios for the common
motor winds. Please consult the motor/esc manufacturers recom-
mended settings to ensure you start with the best final drive ratio
(FDR) for your equipment. When setting your mesh you want to be
able to slightly rock the spur gear back and forth without
moving the pinion gear. Tekno RC is not responsible for
damage done to your electronic equipment or gears due
to improper gearing or mesh.
* For bearing maintenance, please refer to page 30.
Softer springs will increase traction through the turns by allowing
more roll, slow down the responsiveness of the vehicle, and can
be better in the bumps. Stier springs will increase corner speed
if traction is available and will also tend to jump and land better.
Once you find a set of springs you like you will typically only
change them for tracks with dramatically dierent conditions.
Sway bars are used to adjust a
vehicle's lateral grip by resisting
chassis roll. A thicker bar
decreases roll more than a
thinner bar will. More roll means
more grip and less roll means
less grip. The front sway bar
aects mainly o-power
steering at corner entry. The
rear sway bar aects mainly
on-power steering and stability
in mid-corner and at corner exit.
Pistons with smaller or fewer holes work well for smoother tracks with large jumps, and pistons with larger
holes or more holes, work well for rougher tracks with less jumps. Smaller hole pistons will typically use
thinner oil than larger hole pistons. Shock oil is also aected by the ambient temperature so a change in
viscosity might be necessary with a change of 5°C or ~10°F.

Front: Changing front di oil aects overall steering response. Thinner can increase o-power steering but
the vehicle may be twitchy and harder to drive. Thicker can increase on power steering and stability. We
recommend 10k to 20k in the front di.
Center: Changing center di oil aects the front-to-rear drive balance. Thicker will reduce o-power
steering and on-power rear traction but increases on-power steering and acceleration if traction is available.
Thinner will increase o-power steering and on-power rear traction but reduce on-power steering and
acceleration. We recommend 20k to 40k in the center di.
Rear: Thinner rear di oil increases o-power steering and reduces traction into a corner. It also reduces
on-power steering and increases traction out of a corner. Going too thin will make your vehicle inconsistent,
however. Thicker rear oil will have opposite eects, and once again, going too thick will make the vehicle
inconsistent. We recommend 7k to 12k in the rear di.
