    Good prop, might be slightly too much pitch.

    14/18 would be better for CC.

    +1 might be too much pitch. If you're buying a new prop anyway you might consider having Skat make you a new 3-blade setback prop. That would be good for cc racing.

    last time i tried a 3 blade 14/19.. could get the rpm up 8120.. sometimes 8200.. midrange was good but top speed wise was not so great as the speedo meter only could do 68... maybe 66 on average.. whereas the stock prop would be able to hit 70 quite fast..

    too much pitch means less acceleration or less top speed?

    whats the difference between a normal skat prop and a set back skat prop? the prop sits closer to the vanes?

    15/19 or other 3 blade prop don't Works good on X models. Try a 15/22r with 2mm set back. After install it, your rpm with 4 kanaflex and free flow: 8080rpm, very good rpm to closed course. Oh, don't forguet the R&D intake grate for closed course or Riva. To flat water use the best with this setup on Rxp-x is r&d +3mph intake grate. 74mph on sea level...

    Good luck!!

    Top speed in CC is less important then hookup and mid range. Dont trust the stock speedo, they are highly unaccurate.

    All this being said the best performing stock RXP-Xs I have seen run the stock 4 blade prop. They have been worked abit but its still the stock prop.

    +1 worx for CC is good
    15/19 skat is too big for cc
    it has good midrange pull, but is worse than stock prop from the holeshot
    try 14/18 IMO
