Use the following formula to calculate the overall ratio:Īll models equipped with Velineon Power System and upgraded drivetrain components. This temperature test assumes that the model is close to factory stock weight and operates freely with no excessive friction, dragging, or binding, and the battery is fully charged and in good condition. This is an optional spur gear for the Traxxas Rustler VXL and Bandit VXL. Traxxas includes a massive 28t pinion for high speed running, but thats literally only for straight-line speed runs on pavement. But at that point, the top speed is so slow, its pretty boring. For a 3900Kv motor, and not buying any pinions right away, I'd go with the 16/86 combo (pinion/spur) when running on 2S. You can't expect the motor to last long if used continuously. For more low end, you could try going down to a 17t pinion or getting a 90t spur. That optional gearing that's included with the Rustler is meant for doing speed runs. If the battery is extremely hot, and/or the motor is too hot to touch, your model is probably over-geared and drawing too much current. The stock gearing, 19t pinion and 86t spur is fine for most running. When using higher gear ratios, it is important to monitor the temperatures of the battery and motor. Use a higher gear ratio (numerically lower) to increase top speed. Use a lower gear ratio (numerically larger) to reduce current draw and temperatures. For other applications, refer to the model manufacturer’s documentation.Ĭhanging the gearing allows you to fine tune the speed of the model and control the temperatures of the battery pack and motor. The following gearing options cover Traxxas Rustler, Bandit and Stampede models. A sign, that more Amps are going through.Battery choice and gearing determine the speed of your model. Keep in mind, most of these models have many variations. Models Here is a breakdown of the some of the more well-known models Traxxas sells now. If you choose 3S it should already be reduced to 10/54 or 9/54 unless you drive on road.įor me I still use 11/54 with 3S Lipos and 5" wheels (3" rims) off the road and have so far no heat issues.įor now I don't worry too much with the current outside temperatures. The X-Maxx was a game changer for Traxxas. ( Create a multiplier by getting the ratio between the old and new wheel circumference and apply it to the pinion size )ġ1/54 is the standard for running 2s on any terrain. I was going to try the high speed pinion, but until I can find. The tsm helped on dirt, but holy crap this thing will go. I put a 3s in it and it was honestly too fast for me. It would require some measuring and calculations to translate the larger wheels into a comparable pinion/spur combination. Let me tell you, unless you have nothing short of a runway, the stock gearing on 2s is plenty fast. Larger wheels is the same as changing to a pinion with more teeth. I just had a look at the Rustler VXL manual.Īround page 27 is a table that shows recommended pinion/spur combinations based on your chosen battery and the terrain that you plan to drive on.

The Traxxas motor (blue) with 30T/76T gearing is very close to the Castle 5700kv motor using. Motor And Gearing Traxxas 71054 1 User Manual 28. Speaking with msuk and there suggestion going down teeth if I'm getting over heating, so from my 11/54 they are suggestion 9/54 that does not sound right tho to me?. So grab your gears, turn on your calculator, and buckle in.
