In the RC world, one of the common debates is whether to go with a sensored or sensorless brushless motor. On the surface, both deliver the speed and efficiency that made brushless tech such a big leap forward from brushed systems, but the way they behave on the track, trail, or water can feel very […]

If you’ve spent time in the RC world, you’ve probably heard people talking about sensored brushless motors. For a lot of hobbyists, especially racers, this setup is the gold standard when it comes to smooth, precise power delivery. But what exactly does “sensored” mean, and why do so many of us swear by it? What […]

On an RC car, the relationship between the pinion gear (on the motor) and the spur gear (on the drivetrain) determines your gear ratio. When you run a larger pinion with a not-so-large spur, you’re gearing the car toward higher top speed at the expense of torque and thermal efficiency. Here’s what that means in […]

The stock BT01 motor mount can break VERY easily upon higher heat from the motor. Fortunately you can use third party metal motor mount for MB01. Some plastic on the bottom chassis must be filed away for this metal mount to fit in.  

Chasing the Sweet Spot: Pinion and Spur Gear Combinations in RC Ask ten RC hobbyists about the “best” pinion and spur combo, and you’ll probably get ten different answers. That’s because there really isn’t a single “perfect” setup—it all depends on your motor, track, battery, and what you’re trying to get out of your car. […]

For the Tamiya BT01, this is the max (36T pinion, 55T spur): If there is a gear module (mod) or pitch mismatch between the pinion and spur gear, the meshing of the two gears will be flawed, leading to a number of mechanical problems—some immediate, others more destructive over time. The module (used in metric […]

Using a large pinion gear on an RC car changes the gear ratio, which can significantly affect the vehicle’s performance and durability. While it often leads to higher top speed, it comes with several drawbacks. When you install a larger pinion, you’re effectively increasing the gear ratio, which means the motor has to work harder […]

Stock is 61T, and we changed it to 55T. Pinion stays at 25. Stock 540 silver can. Mild speed improvement over 61T + 23T. Seems like upgrading to brushless can give more. No doubt you can use a 29T pinion, and that should make quite a difference, but then the motor will get overheated very […]

The TL-01 is well-regarded for its balance between affordability and performance. It was widely used for both casual street racing and light off-road driving. While it has since been succeeded by newer models like the TT-02, the TL-01 remains a classic among RC enthusiasts. The TL01 by default allows you to use 19T, 21T or […]

One very good thing about the BT01 gearbox module is that you can test fit the gears and make sure they mesh well before plugging it back into the chassis. With TT01, TT02 and TA02, easy test fitting of gears is diffult if not impossible. With BT01, it becomes real quick and easy.
