    3 or 4 blade prop

    I've got the riva stage 2 minus the prop. Now I need to purchase one along with some other goodies, should I go 3 or 4 blade and what pitch if I do go 3?

    If you want to lose 1+ mph, but gain midrange acceleration then the Skat 14/19 is the way to do. Bttek is sitting on plenty of them he would love to get rid of.

    You don't sell them? I was hoping to pick up a couple of things all in one shot.

    I have had the opportunity to sell them, but i declined. I sell the Riva-Skat 15/18 or 15/19 3 blades which i have found to be superior thru my testing. Why give up top speed when you can have both better acceleration and a increase in speed?

    I agree, should I go 15/19?

    the Riva-Skat 15/19R is the hot ticket. Pitch accordingly for top RPM's and you will be rewarded

    Jerry, do know if a stock 15/19R three blade would be easier to spin than a stock 15/20R four blade?

    Also, can you add or remove more pitch with a three blade vs. a four blade?

    15/19 is easier to spin than 15/20

    Either is easily pitched. You have to tend to file the outer diameter of the trailing edge down on the 3 blades when adding more pitch to them.
