A stock 130 size motor is not for crawling. What you need is a tamiya universal gearbox.(i have it and like it)you need high performance carbon brushes and neo mags for better performance. A hitec hs 55 servo is good too but takes more work to install. There is the hs 81 and hs 85. I wouldn't use the hs 85 because no body has used it. I might use it for a second crawler when(if ) i get my friends truck.
hope this helps
