I am looking to get new servos for my 1/8 E-Buggy and 2wd Buggy.

What is good servo for the 1/8 and 2wd buggy?

Should I get fast servos with less torque or slower servos with a good amount of torque?

P.S I have No budget

Well, what radio gear do you use? I usually like to keep my servos matched to the radio. If you don't really care to match, then I suggest Kopropo rsx series. Steering you want to go high torque (for larger tires since youll be running 1/8) and decent speed. And for throttle a high speed will be fine.

I run a Futaba 4pl radio

If money is no issue Futaba BLS series all the way.

Ive just bought a S9351 for my e-buggy and a S9452 for my 2wd SC

why not just get fast servos with good amount of torque
