Hi,Which motor did you win on ebay?I was keeping my eye on some of the .21s.Do you win it this week? On the .21 your boat need to be smaller then 1/8.you need a 1/10 scale.The 1/8 scale is to big and to much for the .21 motor.Your boat need to be 29-36 inc long. Thats what all the boats that I see that has.21 in them.The shock wave has a .32 motor in it.That the same block size, but bigger cc.I'm running a ABC h-4.I was told that would be a good prop to start with.Here's other props octura x440,x442 prather 215,220.All of these props are hydro's.That's what I got. I don't know what prop to use on the deep v's.But I'm sure the other guy's will tell you and help you out with.
