I dropped the Ryobi cylinder in my 1/4 scale Cub last night to check on the JB weld plugged decompression slots. It's still hanging in there OK, looks the same as when I first put it in. I haven't had a chance to fly the plane as much as I'd wished, but it did have several tank-fulls through it. The motor is down a bit (200 RPM) from what it could do in the early spring, but that might be due to the warmer, humid ambient. It still hauls the 17 pound Cub well enough that I think I'll build floats for it this winter.
