120 for a .2 is good as long as it's intact, I went for the .3 because I wanted to try geared diffs.
Sunday I sorted a few important things and made it loads better, but then again I was happy with my .2 but like my .3 it took me a while to get there.
Ball diffs in the b44 are adjustable quickly at the track but geared need oil changes for that effect, saying that I think once you have the right oil your less likely to change it so no more messing there,this is how I think it with the bonus of not having to rebuild the diff cos of busted gears or balls.
The .3 does seem very different and I know I will get it running better than the .2, also noticed so far motor temperature's haven't been to bad and I have up'ed the timing on the esc a step.
