I've got the Dynaflite PT-19, and it would make a GREAT second plane. It will fly fast with a more powerful engine, and it will slow down too. It has a flat bottom wing so it wont fly inverted very well, but the guy I got mine from would knife edge it, loop it, and I'm guessing he did rolls too because I saw him to an emlemen(SP. Anyway, the half loop followed by a half roll to level). I saw one at a scale competiton a few months ago in the expert class. It will tipstall with enough up elevator, but you have to be going REALLY slow to do that.

I've also got the World Models P-51 40 sized, and I LOVE THAT PLANE!! It flys like a sport model, not a warbird. It will go fast like a P-51 will, but it slows down just fine for landing. It's got retracts so you have to be careful on landing, but I've landed it in 3 inch tall grass with the tiny wheels it comes with before without a problem. It just stopped fast and took half throttle to taxi back... The retracts dont colapse like alot of mechanicals will, and mine havent bent yet. Just make sure your servo arm is paralell with the the pushrods and that it is a long one. That'll put the least stress on the clevices and make sure they dont pop off. I had a problem with my arm moving too far and making the clevices pop open even with the fuel tubing around them.
