Yes, the Jett muffler is red. I removed the 2oz. spinner weight and added "dead" weight behind the firewall to re-balance for the manual recommended CG (125mm behind leading edge at the fuse). I also toned down the throws to 50% of recommended for low rates. I plan to takeoff and land on high rates, which are still at the manual rec. throws and fly on low rates. I need to re-tach the engine, but thought when I bench checked, it was spinning in the upper 17K range with a 10x6. I've put a 9x6 APC on for now and will be more analytical for my own concern, and for those interested. Current "all up weight" w/o fuel is exactly 5.50lbs.
