diffs

[IceMike]

is there such a thing as a multi setting diff. i know how you normally set a diff up but was wondering if wit 4wd there is a multi setting one?

What would you expect from a multi-setting diff?

[IceMike]

when looking in the b44 instructions it shows the diffs an loads of settings. bit i dont know wot they all mean as it doesnt have very good descriptions.

i know how you normally set a diff tight then an 1/8th bac but im confused

I have only ever seen two ways of adjusting a ball diff.

One is with a screw/nut/spring that sets the pressure.

The other is with spring washers which is something Tamiya did with their older cars. But in reality these diffs were not adjustable, if you removed a spring washer it would be far too loose.

It would be neat if somoene would come up with a notched adjuster or similar so you would always get the same pressure setting, or a series of different pressure springs that would go in a fixed diff so you could set your diff the same every time.

Unfortunately nobody has done.

So I assume the B44 just needs tightening and loosening by 1/8th of a turn at a time, just like all the other diffs on the market.

I'm actually surprised we aren't seeing cars return to gear diffs (but nitro style with seals and oil), brushless power now is ample so I don't think you need the efficiency gains so much in mod racing.

I know I would change most of my ball diffs to gear diffs given the chance! Ball diffs are a pain in the backside most of the time...

He means how tight should he have the screw as it says tighten fully then turn back how much you want but he is unsure how tight it should be.

a ball diff is supposed to act as a limited slip diff, so it should feel slightly notchy/stiff, there not made as a tuning aid in the way of, back it of or tighten it up to make it do something else,
