RE: Finished My GP Eagle 580
Probably not. If you don't let the engine have enough air, you'll have all kinds of problems. The engine DEFINITLY won't last a full flying season. I would suggest cutting out the vent on the other side of the prop to start with. Next I think I'd go under & open up the bottom of the cowl from your ( I guess your fill tube) straight up to the exhaust cut out. The cooler the engine runs the better. ( within reason) Let us know how it goes. Something else I noticed. It might be a good idea to replace those metal bolts on your landing gear with nylon. It might save a serious rebuild on a hard landing. Nylon will shear off, not take part of the fuselage with it. Good Luck
