I am not 100% familiar with the DX5 but are you binding with the throttle at lowest position? The problem could actually be with your ESC programming or even a bad ESC rather than the radio.
Yes, lowest position.
The TX and Rx are brand new.
I have another problem that might be connected!?!?
My Rudder servo continuously makes noise like it's trying to move. I can wiggle it and it will stop sometimes but as soon as I move the stick and then let go, itkeeps making the noise. It will also "creep" just a little when I cycle through left/right rudder and letgo. It's either a bad servo oris a symptom of a bigger problem.
