why would i want a front one way in my drift car?

and also what exactly is a one way diff/ what dose it do?

one way diff  is like locking your diff both ur tires will spin at the same time

in correction to moezer, no, a one way does not work like locking the rear diff. that is achieved by a solid spool, a ball diff or of course, locking the diff. the one way would act like a handbrake when u get off the throttle. it locks the rear tyres, making the car achieve bigger drift angles more easily. it is something many people like to use but many dont as it is a b**** to learn to use as the car will be a whole new beast to master. if u do have the patience to learn how to use, it would be a great asset as it helps u recover from understeer and also do longer sweeping angles that look even cooler

Front one ways allow your front wheels to spin in one direction. While on power, your RC will drive like a 4wd car, and off power or braking, it will act as a RWD car. When you break or slowed down, the front wheels will free spin as the bearings only allow them to spin forwards. This makes it act kind of like a super powered spool, where you still have differential action, but neither wheel spins slower then the other. The result is the front gets dramatically more power to the ground. giving you a lot of turning power. Also, as it was said, off power and breaking, you RC will act like it has E-brakes, allowing you to kick the rear around when you otherwise wouldnt be able to.

To clarify about how they still act as a diff, as a spool, both wheels spin at the same rate, no matter what, which will always cause slippage and under steer. A diff works by differentiating the friction or grip between the wheels, and slowing down the wheel with the most grip, while the wheel that slips will speed up. This makes sure theres always equal traction between the two, but the result is a net loss in power on that end, but also the car will wish to pull straight by doing so.

A front one way allows neither wheel to spin slower then the other (as they act like a spool going backwards) but, because they free spin forwards, they will be allowed to speed up. The result is that both wheels cannot spin slower then the front one way, but when they enter the turn, the outer wheel will speed up (rather then either lose speed in standard diff action, or slip in spool action), so you maintain more power with out the front slipping. The end result is that your car will be aggressively pulled through the turn. However, because of how they work, you lose your 4wd breaking on them, which is a perk and a downfall depending on how you want to use it.

I love front one ways personally, but you have to understand that they accommodate a different drive style. You dont have an effective way to brake anymore with out spinning out, but you can achieve a drift at much higher rates of speed, or in situations where you would otherwise not be able to break loose. Also, they allow a greater control over your drift angle mid drift. Say you enter a turn too hard, or at the wrong angle. Rather then either slowing down or slamming into the wall, you can tap the break, increase your angle, and power through the turn.

thank you blue shade zero for that VERY well explained piece of info...!! havent seen a write up on one ways quite as good as yours and believe me, ive seen loads until i (thought) i understood one way diffs, which i realised i havent understood before now btw...!!!

many drifters use a front one way..........a front one way is not so much for high speed, large sweep drifts, at high speeds you could drift a brick, momentum keeps it going. A one way's effectiveness is in tight back to back S turns, with a one way you will be able to switchback from one direction to the opposite direction in a heartbeat. It is not extremely hard to master, if you have decent skills and control and want to drift on a technical layout in tandem with other drifters a front one way will give you the control you need.

Sorry yes, "at higher rates of speed" was a flawed statement. What i meant was closer to, or at your max RPM, where you otherwise wouldnt be able to accelerate to break loose. Thats the perk i meant about being able to break loose at higher speeds. I run HPI super drifts, or old racing tires, so i can get going pretty fast without the worry of loosing control, but with out the front one way, i'd never be able to enter a turn sideways since i wouldnt have the extra RPM to break loose. The front one way forces that.

Yes, it also enables you to perform tighter, more technical maneuvers. Because of the front one ways aggressive impact on steering control, you have the ability to transition very quickly and effectively. Something i over looked since i dont have a track to drift on.
