That's good to hear it's the first and only. The X is a RC on its own level. Get some blue 242 loctite and use that on your grears. And only on screws that go into metal. Use it on your pinon, spur, and on the drive gears in the tranns.. The tires from the factory have a crap glue job on them. You can use super glue or get actual tire glue. Pro-line makes a good glue..just pinch back the edge of tire away from rim and put a little bend of glue under the tire bead..The X is really not made to be ran on the concrete/ pavement but If you want to drive the X on concrete/pavememt. I would get a set of road tires and adjust the ESC into training mode and it will cut the power to 50%. So it will help cut down on the beating and wear and tear on you undercarriage.. Also watch your temps on motor and esc running in the grass. To many speed runs and crap traxxas ESC will be toast.. or anywhere there is more resistance against the drive train... if you need anything or have more questions just post them up we are always around bud
