I think the rear and nose diving is highly driver dependent. I had the opportunity at the dirt nitro challenge to have both Danny of Tekno and than lutz drive my truck. Danny immediately drove it and liked it as I do. Ryan had nosediving issues and wanted more cornering ability (my truck is set up more stable and less aggressive). After a couple laps Ryan still drove the heck out of my truck and was able to stop diving, but for him it required a change to using more throttle up the face of a jump. For me, I let off up the face and still don't dive. That middle where you basically stay constant is where it was a problem. Different setups and mods will change how it works for you and your driving style. For the stay the same speed folks, the battery mod is probably reasonable. My truck has ALL the weight forward though, including receiver and transponder and the back missing some plastic.
