"Howdy Padner" ! Sounds like you already have the basics. Don't have to add height to the tail feathers. Rock solid plane, you'll like it. Suggestion, add a mounting plate just past trailing edge so you can install a pair of Falcon Floats. Re-inforce the plate good. You wont really have any fun with that plane till you discover "playing in the water". plenty more thread tips here to read about. Seeya, MM
