With a one way, the minute you slam on the brakes or completely let off the throttle, the rear end want kick out pretty quick. You need have to figure out how much to ease back, and how much steering to apply to prevent you from oversteering. So here are some tips on drifting with it.
- you need smooth throttle control. If you feather a lot with a one-way (pulsing your throttle), it's going to be difficult since you're starting and stopping the wheels from spinning constantly. Work on feathering less, and try to keep your acceleration and deceleration smooth. Try to keep those wheels spinning, even under low speeds.
- Take it slow. No need to take the drift at full speed when you're learning. Get the hang of it first, and then gradually start going faster on your entry.
- Don't fight with it. The unit needs to work with the chassis and you. What helps is turning down your brakes a little. Since the one-way already acts as an e-brake, you don't need 100% braking EPA. So ease back a little and let the unit do the brake work.
- Try not to steer too hard into corners. Since the one way makes it easier to pitch out, you don't need to throw the steering hard right or left.
Hope this helps.
