Changes to wheelbase can affect 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 off 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 types.  Please consult the motor/esc 

manufacturers recommended settings to ensure you 

start with the best final drive ratio (FDR) for your equip-

ment.  When setting your mesh you want have it set as 

tight as possible, without any binding.  Tekno RC is not 

responsible for damage done to your electronic equip-

ment or gears due to improper gearing or mesh.

* For bearing maintenance, please refer to page 28.

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.  

Stiffer 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 different 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 

affects mainly off-power steering at 

corner entry.  The rear sway bar 

affects mainly on-power steering and 

stability in mid-corner and at corner 

exit.

Pistons with 

smaller holes 

work well for 

smoother tracks 

with large jumps 

and pistons with 

larger 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 affected by the ambient temperature 

so a change in viscosity might be necessary 

with a change of 5°C or ~10°F.

Front: 

Changing front diff oil affects overall steering response.  Thinner can increase off-power steering but 

the vehicle may be twitchy and harder to drive.  Thicker can increase on power steering and stability.  We 

recommend 30k in the front diff.

Center: 

Changing center diff oil affects the front-to-rear drive balance.  Thicker will reduce off-power 

steering and on-power rear traction but increases on-power steering and acceleration if traction is available.  

Thinner will increase off-power steering and on-power rear traction but reduce on-power steering and 

acceleration.  We recommend 30k in the center diff.

Rear: 

Thinner rear diff oil increases off-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 effects, and once again, going too thick will make the vehicle 

inconsistent.  We recommend 5k to 10k in the rear diff.
