Mach .07 General information Type Ultralight aircraft National origin United States Manufacturer Beaujon Aircraft Designer Herbert Beaujon Status Plans available

The **Beaujon Mach .07** is a single-seat, [American](/source/United_States) high-wing, [tractor configuration](/source/Tractor_configuration) [ultralight aircraft](/source/Ultralight_aircraft). The aircraft is available as plans from [Beaujon Aircraft](/source/Beaujon_Aircraft) of [Ardmore, Oklahoma](/source/Ardmore%2C_Oklahoma).[1][2]

## Development

Designed by Herbert Beaujon, the Mach .07 is named for its top speed of 48 mph (77 km/h). Beaujon Aircraft publishes the plans along with six other designs in book form under the name *How to Build Ultralights*.[1]

The Mach .07 was specifically designed to comply with the United States ultralight category and its [FAR 103 *Ultralight Vehicles*](/source/Ultralight_aircraft_(United_States)) rules, including the category's maximum 254 lb (115 kg) empty weight.[1][2]

With the specified 50 lb (23 kg) 250 cc [Zenoah G-25](/source/Zenoah_G-25) 22 hp (16 kW) powerplant the aircraft has an empty weight of 160 lb (73 kg).[1]

Reviewer Andre Cliche says:

The Mach .07 is a beautifully simple ultralight which is reminiscent of the early designs that gave rise to the ultralight phenomenon in the late 70s.[1]

## Design

The aircraft's wing and tail structure are built from [aluminum](/source/Aluminum) and are covered in aircraft fabric. The wing is [strut](/source/Strut)-braced. The Mach .07 uses no structural cables in its construction. The [conventional landing gear](/source/Conventional_landing_gear) features a steerable tail wheel attached to the [rudder](/source/Rudder).[1]

The controls are two-axis, with a side-stick that laterally activates the rudder to induce roll and which longitudinally activates the [elevator](/source/Elevator_(aircraft)) for pitch control. No rudder pedals are installed and the wing construction is greatly simplified by the elimination of [ailerons](/source/Ailerons).[1]

The open frame fuselage consists of 6061T6 [aluminum](/source/Aluminum) tubing and a single open pilot's seat. The powerplant is installed at the front end of the aircraft tailboom tube, above the pilot. Standard fuel capacity is 2.5 US gal (9 L).[1]
