Well, the minimum is for it to not "slip".. so usually if I want to adjust the front diff, I'd leave the rear 2 wheels on the ground.. hole up one of the front wheel, and turn the other front.. and see if it is slipping or it is actually holding up hence driving the rear wheels.. (with some traction on the rear wheels, of course..) And do the same when you adjust the rear, w/ the front wheel touching the ground...
Typically, the front is set a little bit tighter.. as you don't want it to unload when coming out of the corner.. at least that's how on an on-road is set..
Also, usually, people set them too loose in general (front + rear)
If you take a look at the setup sheet for the racers (check those RC article at Tamiya sometimes..) and you will see that they would say something like "rear diff, tight.. front diff, very tight" or something to that effect...

I'll have to re-check the manuals I have on diff tightening - I honestly don't know how tight is "right", or what that should feel like (if the manual doesn't say). I'll have to check the Bosscat manual I found online - much more detail than the paper copy I have. Odd, since they are both for the Bosscat, but mine is weak in comparison (I should print out that online one). I assume my diffs in my cars are proper (since they have held up just fine so far), but I want to be extra sure for BLess.
Heck, I probably followed the manual, but if it was over a year ago, I forgot what I did. I think I'm getting senile. LOL
As an FYI, this site has lots of vintage manuals of different brands. It's not in English, but easy enough to navigate:

Thanks man! I'll double check my stuff tonight (sounds like they're set up ok as is, though).
