While not suggesting that a warbird is a good choice I thought I would answer that question for you. The general consensus is that both the FW190 and Spitfire are easier to fly than the p51. On the spitfire they also built some hand holds into the wing which makes is much easier to hand launch her.

W.r.t. Stryker B lots of people say they learned on these. When you push them on the subject you usually find out that they crashed them more than a dozen times, but the plane is fairly tough. Only thing is, you are back to Aileron/Elevator/Throttle. But it will certainly loop and roll. If you can fly it in FS One you can probably fly it okay in the real world - just make sure you have a *big* open space for your first flight. And personally - I'd still push you towards a 4 channel plane - with your skills (such as I can assess them over the net) pretty soon I think you will wanting a rudder...

Best of luck.
