hosam you will not have any problems flying this plane with a 60 in it and in fact will save you from haveing to add weight in the nose for balance. I had a T.S. 75 in mine and thought it was just about perfect. I don't have mine anymore, I traded it for a 1/4 scale cap and the manual of course went with it but I remember I had the motor mounted at an odd angle so the muffler would line up with the exit in the fuse.
