Very interesting topic..... Dual Rate Adjustment
My understanding is that the Adjusting the Dual Rate only effects the setting existing in the End Point Setting of either Steering or Throttle.
I have been told to keep the Dual Rate at %100 and make the detailed settings via the End Point Setting feature.
For instance, I set my Throttle via EPA as a curve to control the throttle setting very finely. When letting a beginner drive one of our RC Surfers, we often turn the EPA for the throttle down to %50
because often, new drivers use full throttle like crazy the first few times they have a go at the waves.
