Yea, I would say if you like the way the front end is reacting but not the rear try to increase the oil weight in the rear first.
Does anyone sell a battery tray that fits in the front of the losi 3.0 chassis without needing to be cut or trimmed? Does the 4.0 battery tray fit nicely up front? I have my 3.0 tray up front now but I had to trim and cut around the fly wheel etc and it's made the tray thinner and weaker.
