64stang,

It can be done but remember you are converting a rubber model that is structured for lightness to a model that must withstand much more stress and vibration.

I would suggest putting some drafting vellum (or equivalent) over the plans and redesigning the plane. Formers can be where they are now but you should go with the 1/16" planking as planned. You might want to use 3/32" or 1/8" on part of the sides to support the engine bearers or plastic mount. A plastic mount would be easiest, with a 3/16" firewall.

The wings will need to be redesigned for more stress due to more weight and maneuverability.

The stab and elevator must be greatly reinforced. You are no longer just using trim tabs.

For goodness sake, don't try to just add an engine and controls to a rubber model.

I guess I'm suggesting building a plane LIKE the kit. Then perhaps build the kit as a rubber model.

Of course this is only a suggestion. You have the kit and the engine, and must make the decisions. Good luck.
