There is alot more to the real thing then these models, I would never try to compare the two on the terms of difficulty. Being a aviation mechanic for several years and seeing what pilots must go thru in terms of certification and training is something an RC pilot will never have to deal with. However trying to control a aircraft from the ground requires alot of practice coupled in with trial and error, but the good news is crash a model and walk away something full size aircraft pilots cant say.
