While I will agree that the OP should get some building experience prior to trying to tackle a Warbird build, I would not suggest going as basic as a Kadet or Telemaster type airplane. If the OP is already proficient at flying helicopters he would easily be able to handle an Ugly Stik or maybe even a low wing sport airplane such as the Super Sportster. FYI, CG on a helicopter is just as important as it is on an airplane. A tail heavy helicopter gets very pitch sensitive just like an airplane but a nose heavy helicopter can suffer from boom strikes by having to hold a fair amount of aft cyclic when landing.
