XRAY - Model racing cars

I run a T2 and T2R and would like advice on the Front Multi-Diff of the T2.

One a carpet circuit with a 10sec lap, what setting would you run the front diff on, at the moment it is a OneWay but I am getting this feeling I should be running a normal diff as I did seem to find the T2R slighty more stable on the corning on tight tracks.

What advice would you give in choosing between the two ?

I assume we are talking rubber tyres right?

If so then generally I would run a one-way indoors on carpet to get enough turn-in for tight corners. Having said that, it does mean the car will be harder to drive that way. At the recent IIC in Vegas Frans Heinsbroek tried a spool in the front for that very reason. It did not look bad, but his car did suffer massive understeer after the change so perhaps the solid one-way setting or a normal diff would have been better for his setup.

In my opinion indoors it will either be a front diff (set tighter than the rear diff) or a one-way. The one-way will normally be faster, but if your laptimes are inconsistent you might be better off running a front diff. The fornt diff will create more understeer into the corner, so you may need to run less caster or make other changes to your setup to compensate.

tony am i reading thet right?
he fitted a spool and got massive understeer, and then you say fitting a diff will give understeer?

Fitting a diff will give less steering compared to a one-way. But I would expect a diff to give more steering than a spool. Hope that clarifies it.
