Inverza 33 from hangar 9


From a project that began as a "what if" with acclaimed full-scale builder Kevin Kimball and Quique Somenzini, the Inverza is a contemporary concept designed to harness the power of the radial engine with the potential only possible in a monoplane platform. For the finishing touches, Mirco Pecorari shared his expertise by complementing the modern concept with a stunning color scheme.

Although the full scale Jim Kimball Enterprises Inverza™ airplane is yet to be built, you can enjoy the most balanced aircraft ever to be introduced for the aerobatics community. The Hangar 9® Inverza 33 aerobat has been developed to take advantage of both the emerging 30cc gas engine and 180-class outrunner electric power system popularity. Designed by the master, Quique Somenzini, whose pursuit of precision elevated him through the Extra and Yak aircraft series, the new Inverza concept promises to become his next great contribution. With its modern outline and features, the Inverza offers "no compromise" precise aerobatic capability for both scale aerobatics and aggressive 3D. Its massive control surfaces and generous wing area makes it very stable and predictable during the most demanding 3D maneuvers such as those that occur at slow speed, or while in a hover. The design also takes advantage of all the previous designs Quique worked with before making the Inverza not only a new benchmark in precision, but also an evolutionary step toward achieving an aircraft with balanced maneuverability. When setup correctly, no matter what attitude the Inverza is flown, very little to no control coupling is evident whether the maneuver is upright, inverted or knife-edge. The result is a flight experience that's pure even when you're control input is aggressive.

Covered in genuine UltraCote®, its balsa/balsa-plywood structure is strong and light, while Mirco Pecorari's original color scheme offers stunning looks, incredible ground presence and high visibility in the air. Its two-piece wing connects with a carbon fiber wing tube and the ailerons and elevators are pre-hinged with a tight seal so you can get flying faster. The oversized hatch features a tinted canopy, scale instrument detail and an ideal location for the pilot figure of your choice. Other great features include a factory painted aluminum landing gear, plus a factory painted fiberglass cowl and matching wheel pants.

Power it with the Evolution® Engines 33GX 30cc gas engine, the Inverza 33 is ideal for entry-level aerobatic pilots and giant-scale fans looking to modernize with a sensibly sized airframe bursting with performance. For those who prefer electric, the E-flite® Power 180 outrunner on a 10S Li-Po battery system can deliver unbridled performance.
