My transmiter is a JR XG8 and has the neat Snap Roll feature where I can specify defined aileron, rudder and elevator deflections when each of the sticks hit full deflection. This basically means I can fly around on docile movements until I want to do a snap and I do not have to change rates or flight modes to get the deflections I need.
A friend of mine has the Spektrum DX9 and we are wondering how to achieve the same set-up (swapping to JR being the obvious solution

thanks
