Hi I was just wondering how many different servo brands there are and what people think are the best in there experience hope you guys can help

there are MANY (hundreds?) different brands and as many opinions on them. Popular ones I see often are
Hitec, Savox, Futaba, ProTek, Spektrum, JR, Radiopost, Xpert, KO, Reedy, Airtronics.
It would help if you were to give an idea of what you are using the servo for. People can narrow down from there.

Futaba, KO





Everyone else

Nitro off road so would need a fast one for throttle and a one with good torque for steering
