RE: using rudder
I made myself learn to fly the rudder after watching a plane lawn dart after the aileron servo wire vibrated loose. Not a good time to try and learn it then. Now I'll sometimes fly around with out using ailerons just for the practice, in case that ever happened again. I always use the plastic clips after that too. Any way, once you get the feel for it, you don't even realize your using it, but you are.
