I tried running equal scale weight on all four wheels ready to run. For me at the time (with a stick pack setup, 540 2pole motor) it was adding 5oz to the front around the servo and front bumper area like Craig said and removing the rear bumper stuff. The truck jumped very nose down and I actually found myself throttling up to keep the noise up for level landing. It drove decent but was crazy under hard braking lifting the rear off the ground all the time. Also at times the rear felt to lite on power whipping around the corners. Much like the problem the Durango has sometimes. It was too spot on to drive and I could get good laps with it but just not easy to push hard and battle in the front of the pack with. Might be not as bad on a bigger track.
