Depends on your chassis. Savox makes the SH1257MG, but it may not mount centered in your chassis unless you have some type of sliding mount or want to use shoe goo. It's fairly large and heavy for a mini servo and not very powerful compared to other mini options, but is fine for 1/12th scale. It is fast and centers well. I'm using one in my Schumacher Eclipse now, but thinking of replacing it with a Sanwa SRG-HR to shave some weight.
