RE: First step to a corsair
Welcome aboard, RJV. You have made some good decisions so far, and you're getting some good advice. I hope you sort it out and make some choices that make sense for you.
I will only suggest that there are some excellent 60 size trainers out there. One fellow I know put a Tower .75 on a Trainer 60, and learned at about a quarter throttle.
The second plane should probably not be a warbird, either. Maybe a Goldberg Tiger 60 or some such. After you convert it to a taildragger, and fix it a few times after abrupt landings, you'll be closer to building that Corsair. Maybe a 1/8th Pica or some such.
But that's all getting a long way ahead of the game. Enjoy the learning experience. Maybe your tastes will switch to 3D or Pattern, or Giant Scale, or biplanes! Or maybe you'll want a Mustang. Go for it, but take your time. Safety first.
Good luck!
