I currently run a Futaba S9451 in my rat, some people i know run Savox's in there rats.
when i 1st built it i stuck a Futaba S3004 in there as that's what i had spare at the time, but i found the 3004 didn't have the strength, often i'd go into turns & the front wheels remained pointing straight when i had the wheel on the transmitter locked over until some of the speed & inertia was scrubbed.
the Ansmann RTR servo's (at least those i've seen branded as AS servo's) are basically rebadged Futaba S3003's which are 3004's with a plastic bush fitted instead of a bearing.
