AVID RC has released a direct drive system for you Team Associated B5 and Losi 22 owners. The Triad Direct Drive is geared towards stock/spec drivers that can benefit from zero slip, boosting acceleration in high bite conditions.
This unit has also been tweaked to be currently the lightest direct drive unit on the market, using a hard-anodized plate and gutted post for an overall total of just .8g.
I would only suggest this system to those completely comfortable with their car as it does dramatically change the way your car responds. But if you can handle it, expect much faster lap times!
