Good day!
I just recieved 2 T1 parts cars and one has a one way in it. Now I know how a one-way works and I understand the fact that you loose the front brakes. What I would like to know is the performance changes compared to a ball diff and would it be a good or bad thing to put in my car? One thing I have noticed with my car is a push under power coming out of a corner.
Thanks Neil.
Neil - don't bother with a one-way on our track. it will be a nightmare for you. It turns in really hard and allows great drive out of the corner - if your lines are great, that is. If not, it's just too much of a handful and it will cause broken parts on your car and others, too. I've tried it any times and ultimately settled on a spool which allows the benefit of outbound drive and late-braking going in. For larger, more flowing track's it's a hoot, but ours is far too tight for a one-way for the most part.
My $0.02.

Niel, is the one way you received a Xray Multi-Diff? If it is you can convert it from a one-way to a spool with just acouple pins, and an o-ring.
A spool is the fastest way around our track, but its hard on the drive train. If you clip boards, or a have a collision with another car it will break the drive cups on the spool. A diff is alot more forgiving in a collision.

Oh! With your push on the power. if you car is balanced coming into a corner, then try increasing your caster angle. This will give you more steering coming out of the corner but wont get you loose coming into the corner. You will also need to run less front camber in the fronts weels too. (say .5-1 deg max).

A front one-way eliminates your front brakes. So, you have 100% brake bias towards the rear.
What this means is that when you use the brakes, the front wheels never skid, but the rear wheels will skid easily, as the weight transfer off the rear wheels causes the rear to have very little traction. A skidding tire has no lateral stability, so this will make your car swap ends whenever you hit the brakes.
To be effective, you need to be able to run with only the slightest touch on the brakes, and even then only in a straight line. They are normally used on carpet due to the much higher traction on that surface, which is thus more forgiving.
It's pretty much a rule all the time (except for electric R/C cars for some reason) that you want the front brakes to lock up just prior to the rear, which retains stability while braking. If the rear lock up prior to the front, you'll be going backwards far more often than you want to.
Thanks for the info, I will stay with the ball diff. As it turns out the one-way that was in the parts car is missing one outdrive so I can't use it without replacing that.
