FS2002 Cessna 206 Turbine Amphibian. In 1971, Edo Commercial bought a set of floats originally developed by Tritan, the Flying Dolphin. These were pretty big floats, and getting a Cessna 185 or 206 off the water with them was a bit of a trick. This modification replaces the Lycoming IO-520 with the Allison C-20S turboprop. The airplane cruises at 140 knots at 7000 feet. Mikko Maliniemi's file C206_CHZ.ZIP is required. By Terry Richard.
