After racing Losi cars since 1999 or so, I switched over to the B4 this weekend and tried this setup at Thunder RC in Nashville. Don't have the .5 degree hubs, started without weight (1386 grams) and the car felt pretty good but had a little mid corner push. After adding weight to bring the car up to 1510 grams, the car was absolutely on rails. It felt much more planted and had loads more steering than anything I've felt on the XXX platform.
