This is an older Stampede, back before Ithink they came with programmable ESCs. At least, there are no buttons on the ESCor anything, so I'm guessing that means there's no programming. If this needs a new ESC, what's the cheapest one that would do the job? Don't want to put too much money into this old R/C, rather than just saving up for a new one that is waterproof, faster, etc.

Thanks
