like_a_g6 Posted July 17, 2013 Share Posted July 17, 2013 I had an exhaust spring come off & hit my prop on my Polini 110 Thor engine at about 50 Hours. Turns out the root cause was that one of the exhaust springs had sawn through the bracket: Keep an eye on your bracket if you have one of these engines, or consider feeding retaining wire through the springs in case one of them does break free. I was lucky not to add a sunroof to my wing Quote Link to comment Share on other sites More sharing options...
