Thanks Tommy, I appreciate the information. I also think I could reinforce the airframe to run the higher horsepower motor, but I'm just considering the flight characteristics of a heavier plane.

I'm planning on installing DuBro pull-pull on the rudder and elevator. Along with the associated bellcranks, etc. plus flying and landing rigging I think the model will be approaching the upper end of the weight spectrum with these modifications.

I think the RCV will be a good choice. The plane has a lot of wing area (1575 sq.in.) so the lower power motor should fly it in a scale manner even if it ends up at 13-14 pounds. Of course with the relatively small diameter of the RCV, I'll be able to locate the battery near or on the firewall, which will lessen the amount of dead weight to balance the model, especially if I go with a high MAH pack.

By the way, those are some great looking models on your website!
