I got a chance to build one this past weekend and ran it this evening on a dirt track using Hole shots. Totally box stock oils, springs and set up. I was impressed how well the rear stayed planted through the sitchback section and powering out of 180 degree corners, some of which are off camber and even a little up hill. No issue laying down the power onto the straight either, I tried to get the rear end to break loose but she kept tracking straight. It was a bit damp this evening so traction was high for out door dirt but I came away impressed. I'd liked to have tried some weight in the back to see how it would change the feel but it didn't seem to need it. It jumped well, no crazy nose diving or anything weird. I really liked the big shocks too. Nice kit.
