Any simple 4/6 channel radio can be switched easily by the spring change however what you end up with is crossed trims i.e. the elev trim on the opposite stick. Even that can be changed on some radios But it is no longer a 'simple change'. The old Ace micropro offered crossed trims as a program option.

Many computer radios can be changed now with the spring change and a few key strokes. But not all some have to be returned for a program change to avoid the cross trim situation.

I changed over from mode 1 to mode 11 around ten years ago simply because its far more convieniant to be compatable with the majority of flyers in this country.
