Tamiya Ball Diff Help Please! (R/C Car)

[Finchowned]

Hi,

I've got a Manta Ray Ball Diff in my Tamiya M-03 chassis but I don't know how tight it needs to be. First attempt the diff just span and transferred no power to the wheels. Now it turns but it's quite whiney and I dunno how it should feel.

I'm running a 15x3 motor on standard rubbers so it's a bit manic but how tight should the diff feel?

Cheers.

Hi,
The diff should be tight to the point that if you lock both of the outputs the diff pulley itself wont slip, unless a large force is applied. To lock the outputs i usually use two screwdrivers, one through each outdrive and whilst holding these in one hand use the other to see if the pulley will slip.

Hope this helps.
