I'm reentering the hobby after a 15 year layoff. I learned in the popular "Mode 2". There are a number of fliers at the club field that I have decided to join who fly "Mode 4". They swap the elevator and the rudder so that you turn with the left hand (ailerons) and control altitude with the right (elevator). I tried it yesterday and must say that it presented no problems. Does anyone have any experience with this mode after learning in Mode 2?
