Thanks for all the advice regarding the outlet air opening. So much itchy fiberglass sanding that I just stopped and didn't get to it yet. Will make em similar to the ones in the manual. Cockpit as per manual.

I like all your ideas for the choke. I'm shooting for light, since I'm using a DLE 20. I'm going to run it stock to see how much power I have, and if there's plenty, I will put a silencer on it. But that's down the road.
