Mine flew great with a OS 40 FS right up till I had it too rich and the engine started to blubber on takeoff then cleared up and torqued hard BUT I kept it flying as it went back to blubbering however it was now heading right over our pits right into our frequency pole, ripped both wings on the right side right off spun around and landed right on the wheels Did not even break the prop... Just the entire airfrane and wings. Gonna miss the little bipe. Was the coolest looking thing on a flyby
