Ivan's largest and most popular flying boat first flew in April 2001. It features a three-piece wing with the Eppler 197 airfoil and NACA leading edge cuff extending from the outboard motors to the tip. The fin and rudder may also be made removable for ease of transportation. Set up only takes a few minutes and requires no tools. Batteries are accessible without removing the wing. Fuselage is stick construction sheeted below water line and on top.
