RE: New SPA projects
One short flight on the Mustang X today. CG seemed about right, needed a little down elevator and 2 clicks aileron trim. Seems to be a pretty nice flying plane. Elevator and aileron were both too sensative so they need dialing back a little. OS-55AX started up on the first flip and the idle mixture is pretty close - a little rich I think but I had the HS needle sloppy rich for the first runs. I ran one tank on the bench and then one flight. It was very windy and gusty making it difficult to determine what trimming it needs so I just put it away and I'll wait for a nicer day.
Cockpit is a little small but it was a canopy I had from some kit I didn't use and I didn't have to search for a source of something larger.
