The American Champion Scout 8GCBC is a development of the Citabria. All of the changes made to the original Citabria design to make the Scout were aimed at making the Scout a much more capable back country utility aircraft.
Probably the most obvious difference between the Scout and Citabria is the Scout's lengthened undercarriage and larger tyres. This change is aimed at making the Scout able to fly into the roughest of bush airstrips. It also features a more powerful 180hp IO-360 with a constant-speed propeller, giving it improved takeoff acceleration and a higher climb rate. The Scout wings are lengthened versions of the Citabria wings. These longer wings combine with larger flaps to give the Scout short field take off and landing (STOL) performance over-and- above the already good STOL performance of the Citabria.
Included in this package are three variations of the Scout. There is the original, standard Scout with taildragger undercarriage and standard-size tyres, there is a version with taildragger undercarriage and massive 31" tundra-tyres (pictured), and finally there's a version with amphibious floats.
The 31" tundra-tyres look almost comic at first, but they give the Scout the ability to take off and land on almost any unprepared surface, such as creek beds, unprepared grass and beaches.
The amphibious Scout has the ability to take off and land on both water and normal runways. The floats on this version of the Scout have retractable wheels, that are set down for landing on the ground and up for landing on water and during normal flight.
