02/28/2014. Remarks by Walter van Tilborg: "The Grizzly Cub (also seen as GrizzlyCub) was a two-seat Piper Super Cub like aircraft built by Arthur and wife Charlotte Andersen of Fargo, North Dakota, USA. It was in fact a highly modified PA-18 and many of the special features were developed in co-operation with Scott Warren (Warren Aircraft, LLC). The aircraft offered a very good STOL performance and the large oversized undercarriage with so called tundra wheels allowed operations from rough and unprepared surfaces.
The slotted wings were designed and built by Dakota Cub Aircraft, Inc, a company specialized in wings for bush aircraft and had larger than normal flaps and ailerons. Another feature in the Grizzy Cub was the recontoured vertical tail with a larger rudder. N88WY was completed and first flown late-December 2007. The one-of-a-kind aircraft was powered by a 230 hp ECI-Aero (Engine Components International) IOX-409 engine, driving a three-bladed propeller. The Grizzly Cub was being offered for sale during 2013."
