FWD (Throttle Forward SideEXP)/ BRK (Throttle Brake Side EXP)
This function makes the throttle forward side and brake side direction servo operation
quicker or milder. It has no effect on the servo maximum operation amount.
Advice
When the course conditions are good and the surface has good grip, set each curve to
the + side (quick side). When the road surface is slippery and the drive wheels do not
grip it, set each curve to the - minus (mild) side.
