The prop is a super bug smasher which makes burping the Rotax engine a nasty job. I washed off the bugs and tried something I learned from an old A&P…. I “oiled” the prop. I took a little Mobil 4T on a paper towel and applied a thin coating to the front and back surfaces of the prop. Mobil 4T is full-synthetic so it doesn't oxidize and has stayed on the prop for several flights.
So, I flew this morning and I see higher airspeed. Looks like a few mph... Granted, I flew solo with minimum fuel, but even so… I have never seen much over 135 TAS in level flight. This might be an anomaly or wishful thinking, but at least the prop is staying cleaner….
