For Viscous Differential
Instead of grease you can use Silicone fluid in the differential for a limited
slip feel as desired for racing. Simply fill the diff up to the top of the gears
before replacing the ring gear. (Be sure to reinstall the rubber gasket).
You may have to replace the o-rings on the outdrives at the same time
you change to this type of differential if the old ones are worn. Team Losi
recommends 5000cs. fluid for the front diff, 7000cs. fluid for the center diff,
and 2000cs. fluid for the read diff.
