I get what you're saying. You're trying to reduce the wing-loading, right? I don't think you need to go all the way 2x, but use LAR, (looks about right) and see what happens. More power will ultimately make sense. I'm trying an old .35 OS Max on a .25 design. I'm not too worried about it if it flys ok. I will not be flying any combat. I just want something I can throw into the air and have fun with.
