just wanted to point out something about this airplane and using a 1.20 four stroke..............there was one at my field this last Sunday, it had an older style OS 1.20 on it. this engine powered this thing like it was a typical sport plane............had more than enough power even at 1/2 throttle.
i can't imagine why anyone would put a big gas motor on it and spoil the characteristics of the bird by adding all the extra wieght, not to mention the vibration.
To each his own.
Since the SS, powered with a 1,20 foure stroke, requires added nose weight, I'd prefer to add the this weight in the form of the addittional power that a gasser provides.
