Hi anyone have a good condition 582 side mount muffler? The one with the 180* bend in the pipe?

Due to my previously posted incident, I got a new propeller. An Ultra Prop 2 from Competition Aircraft.
Does anyone have experience with one? The owner, Bob Davis, is super helpful. He shipped fas ...

Thanks Richard. The prop was a Kool prop. Identical to Luga prop. Company in Canada. They are very light weight, hollow cf. The company seems to specialize in paramotors……

Richard thanks for the detailed report!
