RE: Flaps or no flaps...that is the question
Regarding flaps; if you don't want to include flaps, why not?
Granted, you don't need them, but they are fun and add to the hobby. If you choose not to use them, fine. If you want to they're available. I've had so much fun with a "Contender" with flaps it influenced my decision to buy the "RV-4". When I get around to building it, you can be sure I will be adding flaps.
Go for it.
