Ive had my revo for about three years now and just about every hop-up that I like on it. It is dialed in and runs awsome around the local track. When I run around the back yard and the ditch down the street it turns fine. When I run at the local track I have to slow way down around the turns or I will run off the track. I removed the bump stops, 200oz servo, and tried several weights of oils in the diffs. I have the center dif with 500000 dif oil. I am running 1000 weight oil in the real diff and 30000 in the front. The 200oz servo has the grunt to keep the wheels turned. I notice that when turning the front wheels are turned but the front end just plow strait. Why? Does anybody have some sujestions?
