@Murat Kece 1 I am super pleased to find this thread. I am about to embark on the same restoration project so this helps a tonne. I also contacted George from 4-max and he recommended the same motor set up.
One thing I was concerned about is that the frise (?) ailerons seem to have very limited throw. Knowing yours had flown in the past it would be great to have validation of how much throw you have. I was contemplating mounting servos next to the flight surfaces. Waiting your maiden (and CG experience) with anticipation!
