What came up Tony? There was no attachment. But my aerobatic planes were equipped with special inverted oil, fuel, and prop controller systems that would maintain oil pressure 95% of the time even when the plane was upside down for an extended period. Straight vertical up oil pressure would be lost after 2-3 seconds but nothing was harmed as long as oil pressure resumed after 5 seconds or so. Fuel pickup flop tubes in a special aerobatic tank would keep gas flowing in any attitude. The prop governor had a secondary oil pressure canister because a constant speed propeller needs oil pressure 100% of the time.
The Husky has none of those systems and it's not an aerobatic plane so during a roll I need to maintain a fraction of positive G (centrifigul force) to keep fuel and oil flowing at all times. My Glasair III was safe at +9/-6 G's, the Husky must stay below +3.8 G's (I've never had it above 3 G's).
I was looking up the Boxers and the Lycoming aircraft engines also showed in the searches.
Thanks for the other info.
I had a couple of friends in Longmont, CO that flew stunt planes. One moved to New Zealand and took his plane with him.
