I have a Spectrum DX5C transmitter. I have begun racing onroad after years of offroad racing. When racing I find that the car is very "twitchy" or when turning the wheel, the car responds too fast for my driving ability. I know what the exponential adjustment does but am a bit confused as to the "rates" adjustment and "speed" adjustments do and how they differ.
What I want to accomplish is to make the car react a bit more slowly with steering inputs and not react so quickly to steering.

Any help or advise is welcome...........
