I find this one will take the OS or Saito 91 and have more than adequate power for scale flying and even beyond.

In fact, after two I still am looking for their ARF fuse to get one flying again.

The reason I stress 4-stroke is that rather large cowl. You would need to swing at least a 13" prop to get enough out beyond for adequate thrust. With either engine I mentioned the 13/8 or even 14/7 would work fine.
