Here is how my B42 looks at the moment..
I reduced the ballast from 87g to 52g.
Since I'm using a rather thick anti-roll bar, I softened the rear shocks: oil is Losi 27.5, pistons Losi 55, springs Associated BB white.
..And I am running foams on carpet.
The rear upper plate is made out of fiberglass, same weight, better looks.
Feels so good!!
