WOW, super impressed with this truck. Changed the rear tires to JConcepts Bar Codes and left everything else built exactly to book spec.

Main issue is the gearing in the book. It's way wrong. 13.5 with a 21/84 is way undergeared. Ended up running a 25/84. Plenty of umph for all the jumps, way more top end down the straight and perfect temps coming off the track.

One practice run. Took second first heat. DNF second heat, stripped the motor can!!! Screw backed out and then wobbled around. Had to turn the motor, no biggy. Took second in the main with a nice consistent run and ran two more laps than I did in the first heat. Way better than I expected to run (even if it was a slow night at the track).

The truck is AMAZING out of the box in my opinion. I might play with the front suspension a little. Softer springs, heavier fluid. I think everything else is just about perfect for my local track.
