1. The gear with straight head and single tail is black race steel, which has better abrasion resistance and is quieter. The accuracy is higher.
It's definitely not the kind of zinc alloy on the market. Why do we not use metal? After a long time of testing, we found that the precision of the straight gear with the head and the tail is not enough, the weight is too large, the precision becomes very poor after running in for a period of time, and the sound is relatively loud. Any transmission gears of small-scale cars must be bitten by Saigang, so as to ensure smoothness and low sound.
2. Straight head and single tail can only be used with drift tires, never run with high grab tires, otherwise it will be easy to sweep teeth and even cause the dog bones to twist and break
3. In order to make the bearing fit more smoothly, the straight shaft will be slightly polished, so that there will be a slight discoloration on the straight shaft, please be aware of it.
4. Front one-way
The head one-way is a replacement or upgrade for the front differential. The head unidirectional mainly uses unidirectional ball bearings, which can make the dogbone cup (outdrive) freely rotate forward relative to the head unidirectional integrally, but cannot rotate backward.
When applying power to the front wheels, the head drives the front wheels in one direction, which is almost the same as using a normal differential. But when decelerating, the front wheels can move freely, so that the car has better cornering ability.
5.Straight shaft Solid axles
The straight shaft is a device that makes the left and right wheels rotate at exactly the same speed without any differential effect. The straight shaft can be a solid metal rod connecting the left and right dogbone cups and the drive gear. It is usually relatively light and strong. It is usually installed behind.
