If My Radio has Expo, I use it, then I can get gentle response, but have full control if I need it. If I'm using one of my many radios that DOESN'T have Expo, but DOES have Dual Rates, I open the back of the transmitter and adjust the rates to full regardless of switch position. I will not use D/R due to two crashes that I witnessed, both involving not being able to pull out of a loop. The first guy forgot that his D/R were on and the second turned it on accidentally. If I accidentally hit my D/R switch, I still have full control.
