Design and development

The A3C was designed to comply with amateur-built aircraft rules. It features a single main rotor, a two-seat side-by-side configuration enclosed cockpit with a windshield, tricycle landing gear and a four-cylinder, air and liquid-cooled, four-stroke, dual-ignition, turbocharged 115 hp (86 kW) Rotax 914 or a normally-aspirated 100 hp (75 kW) Rotax 912S engine mounted in pusher configuration.[1]

Air Copter is well known as a designer and manufacturer of gyroplane rotor blades and other dynamic components and they also make their own components for the A3C. The aircraft's 8.40 m (27.6 ft) diameter rotor has a chord of 20 cm (7.9 in) and employs a NACA 8H12 airfoil. The main rotor has a pre-rotator to shorten take-off distance. The aircraft has an empty weight of 250 kg (550 lb) and a gross weight of 450 kg (990 lb), giving a useful load of 200 kg (440 lb).[1][2]

gollark: No.
gollark: I don't like it. We use a BT router with that "feature" at home and I cannot figure out how to turn it off and it *annoys me slightly*.
gollark: Self-driving cars should probably not be using the mobile/cell network just for communicating with nearby cars, since it adds extra latency and complexity over some direct P2P thing, and they can't really do things which rely on constant high-bandwidth networking to the internet generally, since they need to be able to not crash if they go into a tunnel or network dead zone or something.
gollark: My problem isn't *that* (5G apparently has improvements for more normal frequencies anyway), but that higher bandwidth and lower latency just... isn't that useful and worth the large amount of money for most phone users.
gollark: Personally I think 5G is pointless and overhyped, but eh.
