WD40 and a good air compresser. or use some simple green first. and yes always remember SLOW is fast. and when jumping land on the down-side of the ramp dont clear it completely. if you do this you will keep momentum for whats up next. and tires are one of the most important things. look what other racers are using and dont be afraid to try something new. i was like the first one to start using the panther switch tires and now everyone is seeing the light. (hard packed dirt kinda loomy on top) and run the chassis LEVEL!
