What servo is best for my application?

I'm currently running a cheap traxxas servo on my Axial AX10 for steering. I'm looking to upgrade. I'm just wondering what Hitec servo you recommend? I'm only running a Traxxas TQ3 radio. I want to avoid damaging my servos by not having the option to adjust my endpoints. Should I buy a new radio first or is there a Hitec servo with good torque that can run on my basic radio without any fancy setting?

Thanks

You would be better off upgrading the radio system to something with end point adjustments before upgrading to a high torque servo. Once you do that these are my suggestions.

5645mg- ok
7985mg- better
7955TG- best

You will need a radio with EPA adjustments before using any of the digital high torque servos.

DOH! That's what I thought.
