I bought a 2nd hand Hangar 9 Corsair that needs repairs so I'm not shy to hack it up with custom mods. After looking it over I was wondering why the engine mounts are diagonally mounted. I can understand this for a 2 stroke. I like to mount my Saito inverted, any objections?

I am aslo planning to mount the muffler insider the cowl to exit behind the cowl flaps like scale. Which leaves me to the head venting, how have you guys done it?
