Personally, I dislike gas engines. They smell bad. Sometimes they are rather difficult to get started no matter what brand of motor.

For glow...yes a saito 150 would be enough. I flew the 80" stuka with a 150 and it was more then enough. I have a 180 in my first esm me-109e. Nice combo.
Even a saito 125 would fly the p-51b, but yoyd be happier with the 150.

I have the esm p-51b, but put an electric power 110 in it.
