Proud fellow 410 owners, I'm hearing a lot about nose diving with this truck. I ran this truck in 6races in the last 3 weeks. On the last race it started that nose dive crap. My setup has been exactly the same, my driving well I hope it's about the same. So I went to change diff oils, not that it needed it. When I did I noticed the front coupler had come loos a Lil bit, that allowed pinion in diff case to move forward and make contact with the diff case. After resetting it and tightened it back , I noticed it doesn't nose dive anymore. I'm not saying its the problem with nose diving but it is worth lookin into if you are haven this problem. Oh way this truck ROCKS.
