ACDii comment about the prop being a grass cutter was sort of my concern (field is not manicured short) and John's reply about the diehral angle is something I didn't consider. The plane I have is already built (acquired from an auction) and the wing's angle is fixed (probably per the build sheet), so I won't change that. I just don't see how adding airelons woud be a failure. My plan was to add a single servo in the middle and use bell cranks to airelons cut into the wing. While I could use seperate servos, my intent was to keep this at four channels and let the plane always be a entry level trainer. Thinking is most entry level pilots buy minimum plane and radio to get started.
