Three things the Losi needs to perform better when it comes to the suspension. 1. Weight added to the rear end of the truck. 2. Heavier rate rear shock springs. 3. Thicker oil in rear shocks. Those three things will help keep the rear end from bottoming out and bucking as yours does in this video.It's the rebound rate that is too fast as well as the actual overall compression damping that is too soft in the rear end. Unfortunately, tiny rc shocks have no adjustments for dealing them in very well. I saw this same situation with the Yeti Score which I used to own. After I changed those three things it was like a whole new vehicle! I enjoyed your little video all the same though. :)
