Nathan Palmer 6 Posted December 23, 2017 Share Posted December 23, 2017 Could be pilot error so heres what I got. Two flights both end with the prop just stop spinning while on short final. Carb heat on, Cowl flaps closed, throttle retard but not closed mixture rich...the normal setup for final. Cant make out what would be causing the prop to stop spinning. Any idea?

Nathan Palmer 6 Posted December 23, 2017 Author Share Posted December 23, 2017 Will try that. I did it once on one of the flights but just one time. Link to comment Share on other sites More sharing options...

Developer metzgergva 210 Posted December 26, 2017 Developer Share Posted December 26, 2017 Undercooling is more an issue of descent with colder outside temperature and still speeds in the 150+ range. Once you turn final and decent to the runway you need to open flaps to 3/4 as with the low air flow and a bit of power you should keep them above 150C.
