About DLE170
DLE170 is a 170 cc twin-cylinder petrol engine for large radio-controlled aircraft and related aviation platforms. DL Engine rates it at 10.77 kW at 7,500 rpm, with listed thrust of 35 kg at 100 metres altitude using a compatible propeller configuration.
The engine supports 30×12 and 32×10 propellers and uses an NGK CM6 spark plug. Installed performance depends on propeller, airframe, altitude, cooling, fuel mix and integration; the engine is the propulsion unit, not a complete aircraft.
