<font size="2">Recently got a FasTech nitro well worth the money(under $150)with a half gallon Blue Thunder Nitro.It wsa a lot better experience on my first run reading some of these threads before I took it out.The only issue was the coolet slipping which was a easy enough fix.This little boat ran great,been through about 8 tanks so far with no problems except for the prop which is to be expected not being metal and also debris in the water on Lake of the Ozarks.Did order more fromHobby-Sports.com and received them today.Will get a metal later.My question is.....which prop is better,the x435 or the y535?</font></p>
