XRAY - Model racing cars

Hello everybody. I have a question for stick radio drivers.

For get a fast setup in carpet, the car is difficult to drive. Sometimes I need set the EXP Steering to -75% in radio. Anyone know any radio setup for more easily driving?

The corners that have very little degrees, it is very difficult for me turn very little the stick steering. Especially in carpet.

Any suggestions?

You need to reduce the steering exponential (EXPO)

This is the curve that can be adjusted for steering speed.

Try turning it down to -15% or -20%

Some radio's call it something different.
