If you really want a warbird for a second plane look at the kyosho spitfire and the world model mustang. Both of these are arfs and are very tame. Like skier said these are not aerobatic planes but will do the basic loops, rolls, immelmans, etc.

The WM mustang is a little bit cheaper htan the kyosho. You can get it from Quantum models for $169.00 and it goes together in about 8 hrs. A good 46 would pull this plane around just fine.
