Great gears, like spur gears and pinion gears, can help your car run faster and with the right combo of spur gear and pinion gear, you can even get longer running time with the same battery. What's the secret of getting high efficient gears? The secret is super simple – decrease the friction as much as possible and ArrowMax can help you achieve that.

Some people might think that using a bigger spur gear generally gives you smoother engagement, since there are more teeth making contact, more teeth in mesh which helps transfer the power more efficiently as well as spreading the tooth load, through which the possibility of striping a gear is decreased as well. And also in that way it tends to be quieter and less wear. Is that true? When we want efficiency, the closer to each other the gears are, the more efficiency you will get for sure. Friction depends both on force and contact area. As the gear count gets closer, the teeth move into and out of mesh with the least angle and thus the least friction. Well, spur gears and pinion gears from ArrowMax are all well-designed, providing suitable tooth angle and strength for your car.

There are other ways to minimize friction, for instance using special materials with intrinsic low friction coefficients. Just like how ArrowMax did. Except for the traditional plastic material, ArrowMax applied aluminum to their spur gears and steel to pinion gears, which not only effectively decreased the friction but also provided more strength.

Last but not the least, if you are not sure about the spur gear and pinion gear you've got, keep an eye on motor temperature. It will tell you if you're too high geared and speed to tell you if you're too low. Choose the right ArrowMax spur gear and pinion gear combination. It will give you the best set-up for your car!
