[QUOTE=torelentless; correct me if im wrong but doesnt 3 channel have right stick rudder? Then going to right stick ailerons could be fatal. thats just one guys opinion but if my first four channel was a t28 brushless id need alot of parts. good luck whatever your choice[/QUOTE]

Actually you are wrong. The rudder will function in which ever receiver port you choose to plug the rudder servo into. About the only radio systems that may not allow this is the toy grade stuff.

For many years it has been SOP with airplanes that do not have ailerons when used with four or more channel radios to plug the rudder servo to the aileron channel. Now some also for many years even choose to when flying an airplane without rudder with a modern computer radio (almost all are these days) will plug the rudder servo to the rudder channel but also program a rudder/aileron mix and therefore use either or both sticks.
