liquid nos for your xmod and other good info
 

go to your local Slotcar track . ask them for a bottle of COM Drops . then drill a hole in ur endbell on your motor where you can gain access to the commatator when you take the body off . then put a 1 or 2 drops on the com with that liquid . don't use to much or it will bog down . but 1 or 2 drops will give you a huge burst of performance for a short time . good for when you want something on a start of a race . com drops give you double the performance for a short time . also look at the slot car motors . would be a very good upgrade . since you can adjust the timing from the endbells .

also take a extra set of magnets there with you or find someone that has a magnet zapper . so you can charge the hell out your magnets and get them stronger than you think . better performance there 2 . slotcars have the parts to make these thing blistering fast.
