A33N engine completes first flight on HQ55
On April 17 the A33N engine from Cobra Aero had its first flight on the HQ55 from Latitude Engineering. This was also the first flight for the HQ55. The engine and aircraft combination performed well, easily climbing to 13,000 ft density altitude on the second flight. The A33N and HQ55 are accumulating flight test hours and all indications are that the engine and airframe work well together. The A33N is the first engine to be integrated with the Power4Flight IntelliJect EFI system.
