You shouldn't have to program your Dx3 for the reverse. I have the gtb
and dx3 set it up the first time for profile 1 and when I pratice I switch to profile to . When I first set it up on profile 1 I did the full throttle , then the full brake. When I change to profile 2 I don't set any thing different.
My reverse does havea delay because I don't have the DX3 set to a 50/50 profile. If you want I can post on how to reset your dx3 to default settings?
