I have been doing some early beta testing of a classic e415 Ercoupe on skis. They are still a bit confused between the water off Key West and the snow in the mountains of Sion, but the fun factor is stuck on 5+. This is one of the many models intended for AFS2 designed by krzyzk.
The Ercoupe is a pre WWII design with a unique inter-connection of the flight controls to totally eliminate the use of rudder pedals. Every landing is basically a controlled crash until you get used to the feel and sound of touchdown. It was always interesting to watch students or passengers just prior to touchdown in a stiff crosswind. You couldn't crab without rudder input so you just guided the Ercoupe to a spot on the ground and held your breath as it did its thing and correctly pointed the propeller the direction you selected with the "steering wheel" - after hitting the ground.
The e415 was advertised as the "Safest Airplane in the Air". uuh ok.
