Short-field performance is where the STOL CH 701 aircraft truly excels: It is airborne in less than 120 feet of unprepared grass, or 90 feet of hard surface, at gross weight. Rotation is possible by the time full throttle setting is applied, and lift-off can begin at 25 mph (in ground effect, with no wind) - all within less than four seconds from stand still. Of course, any headwind shortens the time and distance required for take off.
