MANUFACTURER: Futaba

MODEL: 9450

TORQUE OZ/IN. : 111oz.(60*)/[email protected]

SPEED 60DEGREE/SEC: [email protected]

DIGITAL OR STANDARD: Digital


COMMENTS: Has more than enough torque to steer the car and being digital, it centers right on everytime. Haven't tried any other brand yet because I've been using Futaba radios and I don't want to mix brands when it comes to radios.

I just bought the JR 8417 digital servo and installed it last night.
This is my first digital servo and I am wondering if they all make a sort of buzzing noise. It's very odd, but I am not sure if thats normal for a digital servo. It says that its an FET servo, but theres no little blue wire to hook it up to my speed control.

Thanks for any response, the servo doesnt seem to be malfunctioning, its just make a lot of noise compared to my other JR Z270 std. servo.

I've been using KO PS2143 and 2123, they boty digital and very happy with the performances.

One question, it also happends to other digital servo even the new ERG-WR from Sanwa, I found the digital servo a bit sensitive to ESC heat temperature. They kind of glitchs a little and can hear the sound its gear moving.

Does it happened to you guys??
