Sonex Aircraft announced at a press and customer briefing this morning that orders are now being accepted for the long-anticipated AeroVee Turbo, with deliveries to commence in the fourth quarter of 2014!

The AeroVee Turbo is rated as a 100 horsepower engine at sea level, and yields significant performance enhancement to the Sonex line of aircraft without breaking the bank. Price of the AeroVee Turbo is $10,995, and an AeroVee Turbo Upgrade package is being made available for installation with existing AeroVee Engines, even those already installed and flying, at a price of $3,995.

In a Sonex Aircraft, the AeroVee Turbo will yield a rate of climb up-to 1300 fpm, and a TAS at 8000' of 175 mph. Two Sensenich fixed-pitch propeller options are being offered for AeroVee Turbo installations on Sonex Aircraft. A 54" diameter x 50" pitch prop is intended for those wishing to maximize climb performance while still retaining a very-respectable 170 mph TAS cruise capability at 8,000'. A 56" diameter x 52" pitch prop will maximize top-end speeds, measured as-high as 187 mph TAS using WOT at 8,000' (38 in HG MAP) during Sonex/AeroVee Turbo flight test. Designed with simplicity in-mind, the AeroVee Turbo is intended for use with fixed pitch, or ground-adjustable propellers, keeping the package Sport Pilot Eligible by not requiring a constant-speed propeller, and with sea level cruise just under the Sport Pilot maximum speed at 135mph TAS at the Max. Continuous RPM specification for the AeroVee Turbo under 5,000’ MSL, 3200 RPM.

The AeroVee Turbo is a pull-through turbo arrangement utilizing the standard AeroVee-sized 32mm AeroInjector. As a "free-floating" system, boost is controlled only by throttle setting limited by a fixed waste gate and power still diminishes with gains in altitude, but losses are not nearly as-drastic as those with a normally-aspirated engine. This allows the cruise speed of an AeroVee Turbo in a Sonex Aircraft at-altitude to eclipse the performance of the 120hp Jabiru 3300 engine.

New From AeroConversions: The AeroBrake Hydraulic Braking System!

AeroConversions AeroBrake
Hydraulic Braking System:

Packages Starting At: $350.00

Sonex Aircraft, LLC is excited to announce another addition to the AeroConversions product line: the AeroBrake Hydraulic Braking System! Due to popular demand, the AeroBrake is the first hydraulic brake product specifically designed for use with Sonex Aircraft airframes. The versatile AeroBrake design may also be used on a wide-variety of other experimental aircraft designs. While Sonex has had great success with the standard Azusa mechanical brake system over the years, the AeroBrake offers improved stopping power and smooth braking action in a head-to-head comparison of the installations.

In-keeping with the Sonex and AeroConversions tradition of providing simple and elegant products for sport aviation, the AeroBrake employs a unique non-caliper design that allows convenient and easy removal of the wheel assembly for maintenance of tires, wheels & bearings. The AeroBrake uses a simple disk as a bolt-on addition to standard Azusa-1137 or equivalent wheels. The AeroBrake assembly retains the same axle-to-wheel spacing as the traditional Azusa drum brake installation, and the entire installation weighs the same as a drum brake installation using AeroConversions Machined Brake Drums. Designed to use a 3/4" axle, builders may use bushings to adapt the AeroBrake for use with smaller axles.

Full installation kits are available for Sonex/Waiex/Xenos or Onex aircraft installation, including a simple and robust master cylinder, allowing builders to retain Sonex Aircraft's trademark universal braking with the existing brake handle form & function, including use of the parking brake detent. Universal (non-differential) braking, combined with Sonex Aircraft direct-steering nose wheel or tail wheel, offer the most positive control of the aircraft while making Sonex Aircraft tail wheel aircraft some of the easiest tail draggers to fly. Builders may use their own alternative master cylinder(s) to mount the brake control to the stick, or if differential braking is desired. Installation kits also include new laser-cut wheel pant mounting plates designed specifically for AeroBrake installation.

The AeroBrake is competitively priced, with packages starting at $350. Upgrade price for new Complete Airframe Kit or Sub-Kit purchase is $300. AeroBrake packages will be in-stock and available for shipping during the month of February, 2013. Place your order today to receive the earliest shipping opportunity!
