I think the 12.25x3.75 is a good 3d prop but the 63s will turn it well over the high RPM limit that YS recommends....Mine turned the 12.25x3.75 at 13,500+ the 14x4w APC worked good but I didn't have much ground clearance that is why I went with the 13x4w APC ...even with this prop it reaches the upper RPM range ....Be careful when you start the 63 as the prop wash may test the 155mph roof and the 140mph shutters....JW (pic#1 is with a 12x4 wood prop ..it turned way to fast)(pic#2 is with a APC 14x4w) (pic#3 is with a APC 13x4w)

JW,
Thanks for the tip on the prop. What do you think about a 12.5 X4 APC?? I think I have a couple of those laying around here somewhere. It will probably be after the holiday obligations are over before I can get started. I did alot of research you know comparing the YS 63 vs the Saito 72, 82 and 100. I decided to give the YS a go and see what happens. Most complaints I have heard are from higher altitude folks. At 15' above sea level (did anyone say storm surge), that shouldn't be a problem here. I would like to get the UCD 46 done first as I am trying to save the 110FZ for another UCD 60 that will hopefully be done over this winter. If not, I'll stick her in Miss A instead of the Saito. Now that we live in the Bastille with our 155MPH rated metal roofing system and our 140MPH rated accordion window shutters, I should't be getting my planes busted up by flying debris
