Dave McDonald might take interest in this shot. It's a shot of the exhaust and plumbing. I used a 2 oz mousse can, tapped for pressure, and 5/16 tubing from the header to the can, and a 5/16 stinger. That size matches perfectly to the Enya header pipe, and I gained an additional 1400-1900 RPM's, as well as muffler pressure (the 80 didnt have one when I got it). It's also much quieter than no pipe.


Next time I have the cowl off, Ill take a pic of the engine install. I have a 91 fx coming, in case this engine doesnt have enough pull, and will put a 8-10 oz mousse can on it for better midrange.


All up weight is under 7 1/2 lbs, and balances around 5 5/8 for its maiden flight this week.
