I am looking to get a new servo for my 12th scale and was wondering which ones you would suggest

Futaba S9650

Depends........how much you wanna spend? I put a Hitec 81MG in mine and have been very happy with it and it's cheap. Try and go small if you can. Doesn't make much since to have a little 1/12 scale car with a big ol' honkin' steering servo in it. :)

I've used these:

In fact I have one NIP for sale for $18 shipped.

Futaba S9650If you can afford this(not much more than a coreless bb servo) than get this, you won't be sorry.

I am not really worried about price

I have a JR 3650 and I really like it,

The JR 3550 is also a good 12th scale servo,

does airtronincs make a good servo for 12th scale?
