Mark, that servo would be perfect in 1/8. Or you can run an Ace 1015, I ran one in my eight for awhile and then put it in my 2wd.

Its a great servo and you can buy a complete gear set for it.

That Jr is insane though. If you want a servo with a lot of torque, but not that much look at this servo.

I have another version of this servo, but it is almost the same one. I have had it for over 2 seasons in my 1/8 and it is in great condition except for the wire. It was melted a little bit when a reciever pack shorted out in my kyosho. It still works with out a problem.
