Delta Thruster General information Type Ultralight trike National origin Bulgaria Manufacturer Avio Design Status In production (2013) History Variant Yuneec International ETrike

The **Avio Delta Thruster** is a [Bulgarian](/source/Bulgaria) [ultralight trike](/source/Ultralight_trike), designed and produced by [Avio Design](/source/Avio_Design) of [Vetrino](/source/Vetrino). The aircraft is supplied as a complete ready-to-fly-aircraft.[1]

## Design and development

The aircraft was designed to comply with the US [FAR 103 Ultralight Vehicles](/source/FAR_103_Ultralight_Vehicles) rules, including the category's maximum empty weight of 115 kg (254 lb). It is German DULV certified and can be flown with any suitable [cable-braced](/source/Flying_wires) [hang glider](/source/Hang_glider) [high-wing](/source/High-wing). The aircraft features weight-shift controls, a single-seat open cockpit, [tricycle landing gear](/source/Tricycle_landing_gear) and a single engine in [pusher configuration](/source/Pusher_configuration). The hang glider wing can be replaced with a [paraglider](/source/Paraglider) wing and requires ten minutes to convert.[1]

The aircraft is intended to be quickly folded into a package small enough to fit into a car for ground transport.[1]

The aircraft is made from bolted-together [aluminum](/source/Aluminum) tubing, with its single or double surface wing covered in [Dacron](/source/Dacron) sailcloth. A number of different hang glider and paraglider wings can be fitted to the basic carriage. A typical hang gider wing used would have a 9.5 m (31.2 ft) span and would be supported by a single tube-type [kingpost](/source/Kingpost) and use an "A" frame weight-shift control bar. The carriage front wheel is adjustable to allow for different pilot leg lengths.[1]

The powerplant is a single cylinder, air-cooled, [two-stroke](/source/Two-stroke), 28 hp (21 kW) [Simonini Mini 2](https://en.wikipedia.org/w/index.php?title=Simonini_Mini_2&action=edit&redlink=1) engine. Without the wing, the aircraft has an empty weight of 32 kg (71 lb) and a gross weight of 200 kg (441 lb). The fuel tank holds 10 litres (2.2 imp gal; 2.6 US gal).[1]

An [electric version](/source/Electric_aircraft) was under development in 2011.[1]
