OK how to determine what engine to use when you enlarge a plan. I have a 40" wingspan model that uses a .15 engine, and I am enlarging it to 80" span sooo do I go by weight of the model?

I would look at wing loading and what type of performance your expecting. I'm currently building a blown up Piper Pawnee from a Traplet Magazine drawing 52" up to 80" and am planning on a 30cc gas at 4hp. color sceme to be Dusty from the Dysney Cartoon. Modified nose from a P-51 cowl. I'm not expecting 3D performance. I'm a fly on my wings pilot, need more than 1ft for take off.
