How to build Cessna 337 / O-2A Skymaster RC Plane from Depron Foam

In the past I already made this type of model plane 2 times before, but all of them only use pusher prop motor. This is the first time I'm using twin motor for Cessna 337 Skymaster. I also designed the papercraft or paper model version of it, it's a commision project so I don't have the template for free share. But using the 3D model for the papercraft version I modify it into this RC model plane plans. It should have been a smooth process, but I made mistake on installing the tail boom. So I need to re-install the tail boom to get it right and fly good. Also I have learned that using PVC foamboard also a mistake if using for key constructions that need rigidness and strength, so the next episode I will back using 3mm plywood.
