Hey guys,

I am building a small twin running two OS .10FP's. I'd like to try and stay scale, so I am looking for a Pitts or similar type of concealed muffler. I know the engine is small and somewhat of a rare bird, but are there any appropriate mufflers out there for this type of application? Ideally, the engine would be mounted inverted with the stacks exiting the cowls on the side(s), however, I could live with them exiting the top or bottom as well.

Also, is there anyone out there who makes 6" or 7" three-bladed props? Smallest I have found so far are Master Airscrew and APC, both of which were 10".

Thanks a bunch!
