I have to agree on the "second plane theory" before a pattern ship type plane.
One of the most important things we have to learn is "AUTOMATIC RESPONSE" IF YOU HAVE TO THINK TO MOVE THE STICKS, THEN IT CAN BE TOO LATE.
I like to put someone in a second plane such as the ones mentioned above or the old R.C.M. FUNSTER or even THE BRIDI R.C.M. TRAINER. top wing semi-symetrical wing.

THE NEW GUY NEEDS MORE TIME TO TRAIN HIS AUTOMATIC STICK RESPONSIVENESS.
YOU DO NOT LEARN HOW TO DRIVE AND JUMP INTO A "FORMULA 1 RACE CAR"
