Come on dude, haven't you already drawn up & built several planes already? You'll have to start thinking like a designer.
They're all great platforms. Pick one that seems most suitable to use as a pattern to build an uncomplicated RC model. Think about what you'll do with the motor, where you'll mount the battery, etc. Think about the plane's size to match the motor you have. Think about what you'll do for hatch access. Simplify the outlines as needed. Build it like a FT kit.
When it flies it'll be a tremendous success for you. A real milestone.
