So, If I know that I need 7"(minimum) for tank and engine then that gives me an idea where the LE should be. I' ve already figured 52" ws, 10"ribs with a tapered(3" root,1" tip) TE, and guessed at 14"tail moment.Does this sound about right?
One other question.
On a nonflapped model what tail volume percentage , I've seen where some had said 14% or even larger.I guess if it's to large you can always decrease it.
Thanks
Steve
