    stock class is just stock
    gearing might be you biggest advantage

    Battery performance can play a major roll in spec racing so you'd be wise to buy a decent one.

    First thing to replace is the stock pinion gear. They are very soft metal and wear quickly.
    The pinion becomes saw tooth shaped and sharp and will eat the spur gear when if you use reverse too much.

    What type of pinion would you recommend then? I have had no problems with the stock pinion being soft. You shouldn't have any problems if your gear mesh is set correctly in the first place.

    My stock pinion did well for about a month (Untill i wanted to change the gearing). I now use losi pinions, and theyve been great for me.
    Oh yea, about the bearings. Teflon and ceramic bearings will provide much less resistance, but i dont think they will last as long as the rubber sealed stock bearings.

    I'm running Robinson pinions now on all 3 of our Slash's.
    I have never chewed up a spur myself with the stock pinion. But after my son went through 3 spurs I found the problem was worn pinion and his more frequent use of reverse. Both trucks had about the same runtime on them and both pinions were hooked badly and quite sharp on the back side of the teeth.

    How are you sure that it was reverse that caused it?

    There is a lot of speed to be rung out of a bone stock truck but it is not the kind of thing you are going to learn on a forum. You need to spend lots of time and effort toying with different ideas and gain lots of experience in setting up your truck. Things like perfectly balanced tires, dialed in front end adjustments, perfectly smooth running bearings, polished gear trains, balanced drive lines, and knowing where and how to save weight are just some of the things experienced and winning racers use to make their trucks faster than every one else.

    Battery type???

    I have recently purchased a Slash and plan to start racing at local track, I also bought a 8.4v 5000 Nimh battery. Truck runs great for stock, but could I get more out of it with a LIPO pack?

    not as much top speed but more power but you need to see if you track allow lipo or not

    If your track allows it I would recommend getting lipo they will greatly improve acceleration which will make it quite a bit easier to clear jumps. Also they won't take the top end down much. The lipo is lighter and will provide a better balanced vehicle

    Also mantain and properly run-in your stock motor...if you have some titans around, dyno them to see which has the most output..that's the one you should use to race. Spray some motor cleaner, lube all the brass bushings using light bearing oil..and add some comm drop prior to race.
    Myth busted: Blitz is not faster on the track.
