C-172 with AVCON 180 H.P STC Conversion
Recently, I purchased a 1974 172M with an AVCON 180 H.P. Lycoming O-360-A1A engine conversion and a Hartzell constant speed prop. I bought the aircraft with a run out engine, so the first thing I did was to have the engine overhauled. It is running like a top, but I was curious if there are other COO members out there who either own one of these or are familiar with one to compare airspeed and fuel burn statistics. I am seeing airspeeds quite a bit higher than a stock C-172 with a standard O-320, but, as a new COO member, was just interested to chat with anyone experienced with this STC. Your feedback is appreciated!
