The rectangular fuselage section offers maximum usable space for occupants and cargo. The 4-seat
STOL CH 801-HD cabin is long enough to fit a stretcher along the right side of the aircraft
across the folded co-pilot seat, while still providing adequate space for the pilot and
one passenger, or two 50-gallons drums can be carried in the rear. Of course, for those
using the STOL CH 801-HD as a utility plane, there’s enough room inside for two to
camp in, and more than enough baggage area for extended cross-country trips.
The large doors offer easy access to the cabin for occupants and bulky baggage, and the aircraft can be operated with the doors removed for maximum visibility and ‘outdoor’ feel.
While it’s maybe not the most aesthetically pleasing, the square fuselage is very simple to build and helps to provide good yaw stability and spin dampening (resistance) due to its flat sides and distinct corners.
