After many years of having our RC Tuning Guide online, we’ve had many requests to put together a Quick Setup Guide with the most ideal tuning options to cure a problem with car handling.
This is a generic list, meaning it should work with most cars, both onroad and offroad, but please take into account that all cars are different and making one change can affect another (see our Tuning Guide Set-Up Order for more info on that).
Reduce Understeer:
• Increase Ackermann
• Thinner front Anti-Roll Bar, thicker rear Anti-Roll Bar
• Increase Caster
• Lower front Roll Center, higher rear Roll Center
• Harder Shock Springs, heavier Shock Oil, smaller (or less) holes in Shock Pistons
• Increase angle on the Shock Mount Locations
• Increase front Weight Bias
Reduce Oversteer:
• Decrease Ackermann
• Thicker front Anti-Roll Bar, thinner rear Anti-Roll Bar
