1.2 size plane is too big for standard (hitec 311). I would use Hitec 645 on the elevator and rudder and 2ea 485 on the ailerons, use the 311 for your throttle.
I disagree, the airplane is a warbird and when flown properly, a standard servo is fine. Isee guys doing aerobatics with 90" Cubs all the time on standard servos and they do fine. A bigger servo like you suggest won't hurt anything, but I don't feel it is an absolute necessity.
