Dave,

I'm about to trade in a Saito 91 on another YS 63S. The only reason why I bought the Saito is that my uncle gave me one that turned out to have some problems but I had already bought the set up for it. So now i'm spending even some extra money to get an engine I can count on. Anyways, I bought some Pro Zinger 14x5 props for the 91, could I use them on the YS 63S? How do you think the 63S compares power wise to a Saito 82 or 91? I've heard they're just as powerful as a 91 despite the fact they can't turn as big of a prop.
