The closer the pinion & spur are in tooth count, the higher the speed. There is also a metric variant on pitch, the module, and the common sizes there are 1Mod, 0.8Mod, and 0.6Mod. I figure why not do some rc wrenching videos. This makes sense; you're nearly halving the Kv, but doubling the voltage — one basically cancels out the other. Without doing the math on the gearing, someone might spend lots more money … The Traxxas motor (blue) with 30T/76T gearing is very close to the Castle 5700kv motor using the stock gearing of 23T/86T. When we start discussing motors, we'll be referring to the Kv of the motor, which is a short way of referencing the motor's RPM per volt applied to the motor (when spinning without a load). This tends to be the most difficult aspect of gearing for people to keep straight, and I find it helps to think of it in a relative fashion. Imagine that five-speed bicycle you had as a kid. This is gearing in action, providing you with a mechanical advantage, whether you wanted to use as little effort as possible to get going, or wanted to get the fastest possible speed. In fact, the popular gearing for a Slash 4x4 with a Sidewinder 8th system is a 20T pinion gear and a 50T spur gear. Traxxas Telluride 4X4 (67044) Transmission & Gearing My Orders Help Shipping Info Contact Us Coupons Hot Holiday Deals! 167 0 obj <>stream Rather, if you can multiply and divide, and are familiar with how ratios work, you're fully equipped to handle the task. One gear doesn't really do you any good by itself, and if two gears have the exact same circumference, they don't help out much, either, so for our purposes, gearing will refer to a collection of gears of varying sizes working together toward a common goal. We usually don't worry about the gearing of the transmissions and/or differentials, because they usually can't be changed — it's rare a company will offer multiple differential gears or transmission gears. Sometimes there is a transmission, like our Traxxas Slash VXL has. First, it's notable that with just a change in gearing, you could gain almost as much speed with the stock motor as you could by changing to a new motor. Finding the right gearing can be a lot or trial and error, but there are many advantages to having a proper gear setup. The tooth count is how many teeth are on the gear, and the pitch of the gear refers to the number of teeth per inch of the gear's diameter. This gives you plenty of speed, but still keeps the temps down overall. We have to work out the math to determine our RPMs going into the transmission. However, it's hard to have this conversation about gearing without addressing another major factor in determining your overall RPM: the motor. If you have a link or picture that says what each gear combination is Forum Traxxas Electric Traxxas Slash Anyone have the gearing chart for the 2wd slash There is really … However, if you wanted to upgrade to a larger battery and larger motor, you're likely to have wanted some more speed and/or performance as a result. As with most things in the hobby, the key to gearing is a healthy amount of trial and error. The most common gears you can change on an R/C vehicle are the pinion gear, which is the gear directly connected to the motor's output shaft, and the spur gear, which is the main drive gear in a vehicle, and usually interfaces with the pinion gear (a pinion can also be a gear associated with a differential assembly, so make sure to use context to deduce which is being referred to). A differential is a collection of gears designed to allow two tires on the same axle to spin at different rates — check out this amazing video from the 1930's for more information on how differentials work; I've never seen a better informational video. I know, I know — the word "math" leaves a bad taste in your mouth, but this isn't high-level trigonometry we're talking about. As long as you are paying attention to the temperatures of your motor and speed control, there isn't a wrong gearing. h�tRak�0�+�M�&*auk)��T?�gCq�����M����q��w���H����兾����-q���•�>��Y���j��V]��p&1rO8K}�|�����=?���d���3k�o�R8.ݪc�>��ZEn;�ݫQ�L�F�Y�6��vʁ�A�4�(��ݮ+�ZWY��O�r��>�H��4&�U�o7p���� � ��� �$ � � "�@��� egtW)���ۊ��n��ҞTyp�A�O>lK(M�]�%�&�ϡSp�C��}��{_B���(B/$� ����WuΖ�ߒ�͔'3��v�Fk�_�޳��zRE1����r���&K��A��_� ���� Let's say we want to change our stock Traxxas Velineon motor out to something with a little more top end, like a Castle Sidewinder 4 with a 5700Kv motor. 4 • TRAXXAS All instructions and precautions outlined in this manual should be strictly followed to ensure safe operation of your model. To maximize your rc crawler's off-road capability, gear the front axle so it spins the front wheels faster than the rear wheels. It's worth knowing 32-pitch and 0.8Mod are the same thing, and can be used interchangeably. You would gear your vehicle one way if you want a lot of low-end power, like for a rock crawler, and another way for a super-fast speed run with a sports car. Second, the more appropriate gearing for the Castle 5700Kv of 16T/90T is practically identical to simply increasing the pinion gear a single tooth for the Traxxas motor. Aside from the fact most R/C vehicles don't have the ability to shift gears, the concept is the same. endstream endobj 168 0 obj <>stream And now the new motor with stock gearing: That increased the RPM by 4,942 overall; a sizable increase, but as I said above, the increase could lead to an overheating problem. With extra time on my hands and no work for two months. We have to keep in mind the pinion and spur gears usually aren't the only gears in the vehicle. Thinking about it this way, it doesn't matter which gear you change - it's applicable to any vehicle, any gear pitch, and any tooth count. If we just swap motors, we'll certainly gain a lot of speed, but we also might have an issue with overheating due to the reduction of low-end torque. Everyone knows what a gear is, but "gearing" refers to the way that the individual gears work together to gain a mechanical advantage. %PDF-1.6 %���� Copyright © 2009-2020, Roger's Hobby Center. Play around and find what works for you! To determine your gear ratio, you divide the spur gear tooth count by the pinion gear tooth count: A Guide to Traxxas' Batteries and Chargers. The Traxxas Hoss 4X4 VXL unleashes extreme RC monster truck fun with the speed and style only Traxxas can deliver. Parts Department Battery Finder Sign in Cart (0) call toll-free 866-729 … (This means the spur gear will rotate once for every 3.74 times the pinion gear, and therefore the motor shaft, does.). Whether you want more speed, or more bottom end, the motor is another point of change when we're talking about RPM. Traxxas Slash 2WD Transmission and Gearing Complete Traxxas Slash 2WD Parts List - Sort By: Quick view TRAXXAS Traxxas Complete Transmission for 1/10 2WD Slash, Rustler, Stampede, Bandit, 3695 … For the purposes of this article, we'll use a Traxxas Slash VXL 2WD truck, though the concepts we're discussing can be used on almost any vehicle. If you wanted to get more speed for this truck, you could either 1) increase the pinion gear's tooth count or 2) lower the spur gear's tooth count. Grab the throttle and feel the Velineon 540XL motor deliver massive torque to … This gets a little more complicated, because you're likely to also switch batteries as well, since the Sidewinder 8th opens you up to using higher voltage packs, which will in turn affect the calculations and final RPM. When you put it in first gear, it was easy to peddle the bike, but you never got going very fast. We also need to know that, to figure out what the initial RPM without any gearing is, we need to multiply the Kv of the motor by the voltage of the battery. Now that we have the equation, we just have to pop our numbers in and determine the outcome. There are some that believe 48-pitch and 0.6Mod are also identical, but that is incorrect — while they may be very similar, over time you will notice some wearing on the teeth where they don't fit together exactly right. The Traxxas X-Maxx forever changed the face of RC monster trucks. Let's begin. If you drop the 2200Kv Castle Sidewinder 8th in your Slash 4x4, use stock gearing, and upgrade to a 4S LiPo, the performance will be almost the same as a stock truck with a 2S LiPo. This is known as overdriving the front axle, and you can do it with your Traxxas … Both of these options will decrease the low end power of the truck while simultaneously increasing the overall top speed. The Velinion system will run for years, but only if you don't stress it. First the stock numbers for a base line. So grab your gears, turn on your calculator, and buckle in, because our first stop will be to look at some jargon and concepts you'll need to know before we really dive in. Let's look at an example using our Slash VXL. As said already, go back to stock gearing and run it as Traxxas intended, or get your wallet out. Other times, there isn't a transmission per se, but maybe a couple of differentials and even a center differential as well. A gear ratio is a measure of how many times one gear spins compared to another one (something we'll get into later). Experiment with your gearing. However, changing a motor will sometimes also require you to change your gearing as well. Without doing the math on the gearing, someone might spend lots more money than they had to just to gain some speed. All rights reserved. The stock gearing is important to know because it is useful to have a baseline to go back to in case you get too extreme in your gearing. One of the questions we get asked a lot has to do with gearing; how it works, what happens when I put this gear on that, can I get better runtimes if I change the gearing, etc. The nice thing about the Sidewinder 8th is the heavier-duty electronics and larger motor and both handle more heat, and dissipate the heat faster, meaning you can increase your RPM and not worry as much about overheating. GEARING CHART FOR CASTLE 1/10TH SCALE MOTORS (Continued on the other side) All motors can be used with either Sidewinder Sv2, Sidewinder 3, Sidewinder SCT, Mamba Max Pro, or Mamba Max SCT … What feels good to one driver might not be great for another. Let's calculate the gearing based on using a 4S LiPo, with a voltage of 16.8 volts when fully charged, and staying with the 2S LiPo for the stock Velineon motor. It all depends on the vehicle. We also need to know what battery we're using. Based on the results from the gearing chart, there's no good reason to upgrade motors if speed is the only consideration, as you can mostly get away with just changing the gearing on a stock Slash VXL and achieve largely the same results. There are a few common sizes we use in R/C, such as 32-pitch (32P), 48-pitch (48P), and 64-pitch (64P). If we wanted to increase our speed, but not as much, we'd also have to adjust our gearing. The best place to start is always the manufacturer's stock , or default, gearing set up. For this example, we'll use a 2S 7.4v LiPo, which should be 8.4 volts when fully charged. Conversely, if you wanted to gain more power, you could 1) decrease the pinion gear's tooth count or 2) increase the spur gear's tooth count. All of us at Traxxas want you to safely enjoy your new model.

If you stopped, however, and forgot to shift back to first gear, if was nearly impossible to get going at all in fifth speed from a dead stop. The reason we use gearing in vehicles (both in real life and in R/C) is because of the inverse relationship torque has with how quickly something is spinning. Trademarks, logos, and images are property of their respective owners.Use of this site constitutes acceptance of our Terms of Use and Privacy Policy. One of the more common aftermarket changes a consumer can make is switching out an electric truck's motor. Its radical new design, massive size, brutal strength, and unmatched power transformed X-Maxx into the stuff of legends. here is a complete guide of traxxas rustler, bandit, stampede, and slash gearing options, and how to change and adjust your gears, demonstrated on a traxxas rustler. But let's say you had a Slash 4x4 and wanted to upgrade to a Castle Sidewinder 8th motor and speed control. As you went through the gears, you were able to go faster and faster with minimal additional effort, reaching top speed when you shifted into fifth gear. So because the only modifications we can do to the gearing of the vehicles usually concerns only the pinion and spur gears, that's what we're focusing on. It can be a bit of a nightmare to figure out how best to gear your truck, but with a little math and a calculator, you can be a gearing expert in no time — or at least good enough to achieve what you're shooting for. So if you wanted to get more torque and less top speed out of our example Slash VXL, you could either up the spur gear to the 90-tooth option Traxxas offers, or lower your pinion gear down to, say, a 20-tooth gear or any other tooth count lower than 23. Quote Link to post Share on … This works out to be very little difference between the two. GEARING CHART FOR CASTLE 1:10 SCALE MOTORS All motors can be used with Sidewinder 3, Sidewinder 4, Sidewinder SCT or Mamba X except for 1415 which is for use only with Mamba X and … So let's try to find some gearing that gives us a little more speed, but also doesn't lose as much on the bottom end. Operate … FIXED GEAR ADAPTER REFERENCE CHART KC2553-R01 Rev 171006 STOCK GEARING SPEED GEARING Model (Model No.) Gearing up refers to decreasing the gear ratio, and gearing down increases it. There are a few key takeaways here. I need one please. Slash VXL Stock Gearing23-tooth pinion & 86-tooth spur.
