Me and my partner are looking for plans for a amphibious four seat airplane. We have a motor, reduction unit, and all reduntant electronics. The motor is a Mazda 13b 6 port turbo, capable of just over 300 hp. Want a high wing pusher. Looking for any plans to use as a starter point. Please let me know if you need more info or have suggestions. similar to bb airplanes mk4
