Sonex Unveils Competition-Capable Sport Acro

April 17, 2007, Oshkosh, WI

Sonex Aircraft, LLC has today unveiled a new aircraft: the Sonex “Sport Acro.” Much like the Sonex Sport Trainer, the Sport Acro is a hybrid of features and option selections for the existing Sonex design, making it suitable for enhanced aerobatic performance, and offering an affordable entry-level aircraft for Primary and Sportsman class aerobatic competition.

The primary feature of the Sonex Sport Acro consists of new, increased-span ailerons. These larger ailerons are expected to increase the crisp Sonex roll rate to a competition-worthy level. Aside from enlarged ailerons, the Sport Acro is a Standard Gear Sonex with a single Center Stick, which is the basic Sonex Complete Airframe Kit configuration. The Sport Acro has a five-point seatbelt harness configured to allow the pilot to sit in the middle of the aircraft for positioning directly on the roll axis, with the added benefit of making the Sport Acro an exceptionally capacious single place aircraft. Upholstery, instrumentation and installed optional equipment have been kept to a minimum in order to keep the aircraft as light as possible. Sonex Aircraft, LLC expects the Sport Acro to achieve aerobatic competition-class performance on just 80 hp, and the prototype Sport Acro has an AeroConversions AeroVee 2.0 80 hp engine under the cowl. Using an AeroVee engine and requiring a minimum of optional equipment, a pilot can build an aircraft for entry-level aerobatic competition for just $25,000 complete.

Sonex Aircraft already are exceptional aerobatic machines. With full aerobatic category G-loading of +6 and -3 G’s at 950 lbs max aerobatic gross weight (1050 lbs for the Xenos Motorglider) and with an above-average load factor margin built-in, Sonex Aircraft represent some of the most structurally-sound aircraft available in the kit aircraft market today. Many Sonex Aircraft customers enjoy the aerobatic capabilities of their existing aircraft around the world, every day. All models and configurations of Sonex Aircraft are also Sport Pilot eligible, and the Sonex Sport Acro will be a Sport Pilot legal competition-class aircraft.

Once flight-testing of the Sonex Sport Acro is complete, and the aircraft has been put through its paces using the International Aerobatic Club (IAC) known Primary and Sportsman class aerobatic routines, Sonex Aircraft, LLC intends to offer a retrofit kit for any existing Sonex or Waiex, and optional Sport Acro equipment for new Sonex Aircraft Complete Airframe Kits.

Sonex Aircraft, LLC is a rising star in the experimental kit aircraft industry, providing a series of Sport Pilot eligible kit aircraft along with the AeroConversions line of products which include the AeroVee engine, AeroCarb and ancillary aviation products. Sonex Aircraft’s Sonex and Waiex sport planes, and the Xenos sport motorglider offer outstanding performance in an easy to build, easy to fly kit package that can be purchased and completed with full technical support at an unrivaled price.
