I got my rebuild done this last week on my cub.... she flies really nice... I love my new 31" ABW's.... Airplane turned out really nice... The downside is I have been flying a buddies airplane all winter that has a 160 and an 82/41 borer prop.... I still have my 74/56 Sesenich and although I cruise at 107 mph indicated with my 31's I don't have the takeoff performance that I have grown accustomed to..... I am looking at going 160 h.p. next winter with a partial "top" but I need to buy a borer now.... I am looking at a 42 or 43 pitch preferable... If anyone out there knows of any well within limits full length borers I would like to hear about them... I am going to look for used until the first of may than I will buy a new one.... Thanks and Happy flying.....
