i believe the stock slash vxl model uses 23/86 gearing. you should be able to go up a few more teeth on the pinion.the vxl system is a good basher system and handles 7 cell nimh and 2s easily, but if and when you bump up to 3s, it gets sketchy. thats when you really have to pay attention to the gearing and heat.
you hear horror stories about the vxl speed control , but yet again, i have never had an issue with the ones i have had. hope you have fun with it.
