The Hirth F-36 is a single cylinder, two stroke, carburetted aircraft engine designed for use on ultralight aircraft, especially powered paragliders and very light ultralight trikes. It is noted for its extremely light equipped weight of 28 lb (13 kg) including exhaust system, reduction drive and carburetor.[1]
The F-36 was formerly known as the Solo 210, before the design was purchased by Hirth.[2][3]

Development
The engine uses free air cooling, single capacitor discharge ignition, with a single integral pump-type carburetor. The cylinder walls are electrochemically coated with Nikasil. Standard starting is recoil start with electric start optional. A quadruple V belt reduction drive system is an option with ratios of 1.8:1, 2.0:1 or 2.5:1.[1]
The engine runs on a 50:1 pre-mix of unleaded 93 octane auto fuel and oil and produces 15 hp (11 kW) at 6000 rpm.[1]
