In 2013 Currawong partnered with Cobra Aero (US) and Power4Flight (US) to create the Corvid-29 engine, a fuel injected version of the 3W-28 engine with a low noise exhaust.
Currawong also designed and manufactured its own engine dynamometer (due to the lack of a precision dynamometer on the market) in order to properly test and calibrate the engine. The Corvid-29 has been successfully integrated into eight airframes.
