Hello Kostas. That engine will be more than enough. For a 60 size plane it is VERY light. I have a 91 2 stroke and it rips through the sky. I only fly at half throttle and full doing fly bys down the runway. A lot of the guys it seems are running 71 Four strokes and have plenty of power left.

I will have to say that you really need to go back and read the posts about the plane. There are some modifications that absolutely have to be done. For instance change the front landing gear. The one that came with the plane is way to flimsy and the plane has a nose up attitude so it will take off way before you want to. So you have to change the front landing gear wheel to a smaller size and the rear landing gear wheels to a bigger size to give it a nose down attitude. I also highly suggest changing the mounting screws. I can't believe a company would even think that wood screws are a good idea for an engine mount.

Please feel free to ask any questions. We will be glad to help you out.

Joe
