    Gearing for VXL

    I have rustler VXL and I most do wheelies in the street or ramming in the back yard. Lots of on off throttle. Is the stock gearing safe with 2s 4000's?The motor seems to get hot but I don't have a temp gage. I just kind of assume that this is how the stock truck would be set up since I think most people would run like this. Is it safe or should I drop a couple teeth on the pinion or what?

    What you should do is drop a couple of bucks on a temp gun and measure your temp. That is the only way to know for sure and a good way to tell if you ever develop some sort of issue with a bind in the drive line. Other wise all you will get is a guess if it is safe temp wise or not.

    You DEFINATELY need a temp guage. That is the ONLY way to see if you have the correct gearing or not...

    I was sort of hoping to hear what others have found with the stock gearing

    Stock gearing generally works in most situations. Odds are you are safe but for the cost of a temp gun ($15-$25) wouldn't you really like KNOWING you are safe or not?

    I bought my temp gun at Harbor Freight for $10. It's pretty much the same as the Duratrax one that tower sells for $25.

    I think I remember the esc can get 150 but it also has thermal protection, but don't rely on that, use your temp gauge you buy in the future and use that. Traxxas says keep the motor under 200*.

    Someone, check me on the esc.

    I wanted to wait until the $59 harbor frieght gun went on sale again but I stopped in the store anyway and they had a neat little temp gage the size of a stop watch. In fact it also has a stop watch. It was on sale for 9.99. I also picked up some additional gears from the hobby shop and asked him about it. He said target temp of 160-165 and that 185 is to hot. When I got home I read the manual again and also saw the reference to 200 and they mentioned a traxxas temp gage to mount in the car. Does that gage have a surface temp patch that you place on the motor or is there a built in thermister in these motors? I ask because if an internal temp of 200 is allowed I would suspect it it something less on the out side of the case.

    well I dropped 2 teeth on the pinion and measured 155. I am guessing it was a lot hotter with stock.

    I'm with dad on this one. With stock gearing and 2s lipo you SHOULD be just fine for most circumstances. With that in mind, $20 for a temp gauge is one of the best investments you can make.

    Is it just me or do those two thermometers look eerily similar?

    The Cen-tech has a fixed emissivity whereas you can adjust it on the Duratrax.

    I take mine with me every time as well. I have some how collected 3 different temp gun and my son has two I think. I use them for my reptile tanks as well as my Rc cars and they are great for messing with the Pizza delivery guys.

    Not to get too off topic but what reptiles do you have dad? We use our temp gun for herps too. We currently have a bearded dragon and fire bellied toads.

    That snake can go a long time w/o food especially the bigger it is. Of course he would make short work of any rodents he found I'm sure but I bet dad will chime in soon...

    Nice dad! We have had several herps over the years and only recently the bearded dragon. It is definately my favorite!

    Hey Dad - you ever take all your temp gauges and see if they all read the same on a single object? What's the old proverb;
