Best training airplane - Sig LT 40. After 35 years of flying everything with wings called a trainer, it is the best.

But just because you can take-off, herd the airplane around, and return to the runway with an airplane that can be flown again does not mean you have learned very much about flying. Using the rudder and throttle is also important, yet if you walk down the line of the average RC field, most pilots won't even be holding the left stick while in flight. Very sad statement about their flying ability. A slight cross-wind on take-off or landing and they aren't controlling the airplane, they are just an observer without control. As in full size, technique and practice makes the difference.
