Squirt, go to www.apcprop.com Good luck.

Speaking of the 17/4 prop, I finally finished balancing and got it on board. WHOA!!!!! Its like putting my truck in low range. I see what you mean about it settling right in to a harrier, even on low rates and will bite into a hover right off. Still, I see alot of stick time to get used to this. Everything is way different with a +. I'll get it back out tonight if the winds quit. Joe
