Not concerned about rotation or anything else for that matter. I'm watching the suspension. I seen a video of Gene's car and it looked like the car was taking the bumps not the shocks. It's been a little tough for me to get these shocks to feel like Losi or HB. I end up with too much pack or the rear hits hard enough to upset the car bad. The car is there. It's good. Turning some fast laps but something is going on with these rear shocks. A few of us are playing with it so hopefully something soon.
