ball diffs.

[fasterthebetter]

Are ball diffs generally harder to turn than gear diffs or have i set it up wrong??? cos mines very hard to turn...[!]

[BiggusDitchus]

With ball diffs the rule of thumb is normally tighten em up tight then back off between a 1/8 to 1/4 of a turn of centre screw. Also once fitted if you hold one wheel and spur gear you should be just about able to turn opposite wheel, adjust diff to this and you should be bout right

A ball diff set right will never be as free as a gear diff.

well then whats the advantages to ball diffs over gear diffs?? why is the price doubled?

[BiggusDitchus]

The advantage is that you can tune them to the track or the surface your running on, in effect a ball diff is a limited slip diff. for example as soon as one wheel is lifted when running a gear diff all power goes to that wheel, with a ball diff if you tighten it a tad then the effect can be lessened.

If gear diffs were as good as ball diffs then you wouldnt have all these experienced rc racers using balldiffs (thanks sjoerd ooops lol). []

which screws do you tighten though to adjust them? theres like 40 000 screws in them!

A Balldiff has one centre screw that holds the whole thing together. This is the one to tighten/loosen. The screw is usually accessed through the diff joint

Is that the one that you have to adjust with the tamiya spanner?
