    Downgearing the Telluride

    Will the 90 tooth spur gear from Slash 2wd fit into vehicle?
    I've just ordered a Telluride and 12/90 gears, planning to do some light crawling and mostly hiking..
    From what i can see the stock gearing is 12/83, and the motors are still fried

    First off welcome to the forums!

    It should fit on the telluride as far as I know.
    And we thought toy grade RC's where cool...

    NO it will not fit in the Telluride. 83 is max with out having to mod the chassis. I tried an 84 and it's a no-go. You can change the spur gear down to an 11t and with the stock 83t spur you will get a 7.5:1 ratio, which is the same as your 12/90 gearing.

    Just a heads up for ya. Even with 11/83 gearing keep a close eye on your motor temps.

    I think it also depends what motor you have on if you can use an 11t. the motor i have has the flux sleeve and it just barely touches the floorpan with the 12, but a motor without the sleeve has a little clearance.

    If you know where to look there are 10t 48 p 3mm shaft gears.

    Thanks for your response, a 10 tooth pinion will be ordered
    I will most likely go brushless when the titan dies... Any recomendations?
    Sensored is a must and waterproof would be nice

    NAH. 32p = 9/54
    48p = 11/83

    11t 48p here... http://www.trinityrc.net/shop/index....&product_id=96

    11t 48p pinion will mesh with the 83t spur. I used 1 sliver of posted note for a gauge. I can force 2 slivers into the mesh but the Telly will not roll. I never tried anything smaller then an 11t. Oh, be sure to clean out the slot where the motor plate stop slides down into the chassis. 32 pitch 9/54 meshes with out issue.

    They haven't looked too hard cause, 7t 48p is the smallest I've ever seen....
    Made for slot cars so I could not tell you what the bore size is.

    Here's a thought: the ring and pinion gears in the brushed Stampede 4x4 differentials are lower to allow for the larger chevron tires. If you swap your ring and pinion gears with those, you will be lowering the gearing of the Telluride in addition to the pinion/spur combo.

    Interesting, I saw those (6779&6778) I thought they were an overdrive gear-set for a slash though. I didn't realize that was front and rear.

    Id just switch out the 12t titan motor for a 21t titan from the emaxx and your down gearing problems and small pinion searches are over. I run 21t titans in all my Axial trail rigs and they are awesome for the price. They handle 3S lipo with ease (if you have the esc for it).
    You could gear the 21t up quite a bit if you wanted the speed, however they seem the most happy with more volts than more gears.

    This is what I was thinking too, but has anybody tried to use a 32p, 56t spur gear on the Telluride yet?

    It'll take the same gearing the slash4x4 and stampede 4x4 will take. I believe 50, 52,54 are the 3 spurs listed for the 4x4 slash. I had one a while back but forget the spur size. I know the stock spur was a tight fit so I would make a guess that the 56 won't fit without some dremmel work. It may not even fit with grinding work, there's not a lot of material to work with there.

    One of my customers ar work was going to try the 56t in a Slash or 4xPede, but I haven't really seen him since he bought the gear last week to ask.

    I did stuff a 90T spur in two tellurides with a little cutting of the case but it was not really worth it. Use the 86 and get a 19 to 35 turn brushed motor to slow it down. We trail run a couple with higher turn motors and they work very well for us.

    If you don't need to go faster than a quick walk when on the trails, you might want to try a gear reduction unit. I tried this on my Stampede and it worked great for hiking on the trails at a local park.

    NAH. 32p = 9/54
    48p = 11/83
    The 9t 32p gear is actually bigger in diameter than the 11t 48p gear...

    Its the same chassis as the Stampede and I run a 56T spur. It fits with no mods but to get the slipper assembly in and out you have to take off or loosen the driveshaft cover to get the angle right. It was the same with the stock motor mount and the STRC mount I upgraded to. It does take a bit more wiggling to get it lined up with the aluminum mount because the bearing fits in there tighter but it does fit.

    I dont mean to bring a dead thread back but I have a question hopefully someone can answer. I am new to RC wife bought my first one for christmas, I have already stripped the spur gear after 5 packs with minimal bashing. I am guessing the mesh was not set right at the factory. luckily enough they are easy to replace, but here is my question and I need to know asap as I want to order these tomorrow morning so they are here in a day.

    I have heard of people going to 32p for the strength? Is this worth it. also I am putting the Castle sct 3800 in it and was wondering what gear ratio should I use, 32p or 48p if that is strong enough. I love the get up and go it has and would really want to keep is burn out happy especially 'drifing' in the turns on baseball fields I dont want it to go stupid retard fast but a 45-50mph max would be great, I will be running 2s lipo batteries most of the time, but it may see a few 3s when Im feeling crazy.

    Anyhelp?

    Whenever I gear a new setup, I plug my values into this calculator with my intended tire size, kv, and voltage to see what gearing gives me my target speed. I'll start there, then adjust by temperature . If going to a 3800, I would swap to 32p gears personally.

    The 3800 is awesome, but 45-50 may still be tough to get on 2s.

    Thanks you for the input. I have no idea about this stuff yet but the addiction is growing fast lol. Is 40 possible? It does probably over 30 right now with the 12t and 5000 nickel batteries.

    And I'm definitely putting the slash slipper with 32p in just need to know what spur and pinion to use.

    I was hoping someone on here has already done the mod and can help me without all the trial and mostly error.

    That site is cool but I have no idea about the pinion gearing or transmission gearing that is in these?

    You just select from the drop down menus. I don't believe it has an option for telluride transmission, because there isn't a transmission really. So plug in a value of 1. As to pinion, you put in whatever size pinion, and whatever size spur, you intend to use. So, if you want 40 mph, you plug in different spur and pinion combinations until the output is 40mph when calculated. Actual will be less than calculated, so play with the calculator until it gives you maybe 43 mph or so. Then I'd install that gearing in your truck. Maybe start out with 15/52 pinion/spur in the calculator(if swapping to 32p) and see what that gives you. Larger pinion will calculate for more speed, as will a smaller spur.

    I believe 40 mph on 2s would be entirely possible.

    I run the 3800 in a slash, but on 3s, and can't tell you right off hand what it's geared. But you k ow what they say, teach a man to fish....

    I appreciate the help lol. Fishing isn't my problem, I own an offshore lure company haha so the analogy fits well. Www.luremin.com

    I'll give the calculator a shot and see what it comes up up with.

    I don't know what the diff gearing is but u picked the Stampede as I think they are the same of 1 I may be hacking something up because I'm getting around 100 Mph with a 10/54 setup lol.

    Yeah, stampede vxl, or slash vxl diff gearing would be identical.

    This should get you close, if the battery is very high c rated and at least 5000mah. That's pretty high gearing though, but the 3800 May do it.

    I messed up on the diff gear ratio I beliebe which makes sence because I was getting about double that number. the voltage though shouldn't that be 8.4V?

    I was putting in for a 2s Lipo. If you'll be using nimh, yes. But, be warned. That system is an amp hog. I think you'll find it won't run right on nimh. I have trouble with mine on a cheap 2s pack. It stutters on takeoff. With a higher quality 2s pack it's fine. Or with 3s it's fine. I think nimh might be even more prone to do that.

    oh ok I wastn aware a 2s was that voltage. ok I think im going to order an arrangement of pinion gears. Seems weird though I talked to a guy at trassas just a moment ago and he has a telluride running on 2s with the trassas brushless 3700 motor? and he said he gets his up to 50 with stock gearing?

    What would be some good batteries for it that aren't crazy expensive as well as a charger?

    The traxxas motor is 3500Kv. But, at any rate, I would doubt anything else that fella ever told you, lol. 50, on 2s, with the vxl motor, I doubt.

    For a budget charger, I really like the 6 amp ez peak traxxas charger. Some of the best, and cheapest, 2s lipos would be from spc. They have an awesome hard case, 50c, 5000 mah pack for around 35$. You could always get a 3s as well and really push your speed up . The 3800 is pretty quick on 2s, though.

    You might wanna spend some time in the stampede 4x4 forum. There is more brushless activity there.

    Thanks man, Im going to get some of those as well. I will probably have a few 2s, and just one 3s when I want to really mess things up lol.

    I ordered the slipper from the slash, it comes with a 54T 32p gear, Im going to keep that on there and see if I cant dial it in with the pinion gear, I ordered 13T 15T 17T and 19T that should give me a good range to try out yes?

    Yeah, that'll be a good range. There isn't much difference in a 52 tooth and a 54 tooth spur. Either will do just fine. A tooth on a pinion makes a much larger difference than a tooth on the spur. If you go with the larger 2.8 tires, you'll pick up a little speed from that too.
