RE: Is my plane underpowered?
The subject is not nor has it been teaching full scale.
My opinion remains: The idea a three control airplane cannot be used for intial training because it does not have ailerons is indeed absurd!
I can assure you I and I doubt the original poster could care less what the 'Model Aeronautics Asssociation of Canada' or you may attempt to "Stipulate" means nothing to me an American.
Have I good evening Ed.
