RE: 3W 75---anybody have one--?
I have the 75i and am breaking it in on a 24x10 like Cactus aviation recommends. On my very first run it tached at 6400 rpm slightly rich. Now I have 10 flights on my CA extra 31% and it will hover at about 1/3 throttle (the plane is 21lb. and the field elevation is 5300 ft.) The engine is now taching at 6800 rpm and getting stronger all the time, awesome. How soon can I go to a 26x8 or 10?
