Based on the success of the STOL CH 801-HD as a commercial spray plane (a.k.a. the CH-8000), Zenair has quietly been working on an even larger and more capable STOL aircraft than the currently available HD model. Among other modifications, this new CH 801-EX has 4 feet of additional wing span, a larger tail, a sturdier cabin frame and a beefier landing gear - all for an increased design gross weight of up to 2,700 lbs.
The new design is a “Special Project” being assembled together with a US-based builder and will feature dozens of top-of-the-line accessories and custom-features; it is not intended to replace the CH 801-HD. No "upgrade" kit or instructions are planned to convert the smaller and lighter original or HD models into this larger “Super STOL”, but the new CH 801-EX should soon be a new option for builders/pilots wanting a larger 4-seat aircraft with more power and additional weight-carrying capability.
The first North American STOL CH 801-EX will be finished later this Spring, in time to tour this year's major summer fly-ins including AirVenture in Oshkosh, WI.
