Front One Way And Rear Ball Diff

Front One Way...

Just as described, the front wheels are only allowed to turn one way... A one way bearing in the diff prevents the tire from spinning backward... While on power, both front wheels get equal power (no differential action)... Off power, the front wheels free spin on their own accord... This give high initial turn in, and allows you to really pull through the exit of a turn, as both front wheels are applying maximum power to the ground... Breaking becomes an issue, as the nature of the one way does not allow breaking to effect the front wheels... In effect, its like yanking the e-brake on a car... With out proper attention, this causes the car to loop out much easier, and makes it twitchier at speed...

The benefit of front one way on RC drifting is to minimize understeer... When using front ball diff, more understeer will occur and it is very hard to drift in tight and S-turn corner... Besides that, the angle that the car make is not that beautiful... The downside of using front one way is the car is harder to drive... But once you master it, it is actually as easy to drive as a front ball diff... Most RC drifters prefer to use front one way over ball diff...

Rear Ball Diff...

So what is a ball diff??? It’s a clever little device that takes up the difference in rotating speed between the left and right side driven wheels... Unless a four-wheeled vehicle is traveling perfectly straight, its left and right side wheels travel on different paths, at different speeds... The diff compensates for this while providing drive force to propel the vehicle... Without a diff, one or both of the driven wheels would be dragged across the road surface, resulting in a loss of traction...
