I have a jr 9100s setup for my throttle/brake on my 8ight, i noticed before i ran it the servo will twitch a bit at random times , wondering if anyone has had similar issues or resolutions to the problem. Its being run from a 6v batt that came with my 8ight, thanks for your time and responses.

How much does it move when it twitches?

What radio system?

it twitches alot! might move like 1/8- 1/4 of an inch at its worst. using spektrum dx3s, looking at upgrading system though have been looking at radiopost ts401

That's a lot of movement, there is definitely something wrong there. I'm inclined to blame the spektrum receiver, but it could be the servo, perhaps it is worth trying a glitch buster capacitor. Just search 'glitch buster', they aren't hard to find.

Isn't the glitch buster for elec setups? This is on my throttle/brake servo , I only have a hump pack on the trug

Foxy

They are normally for electrics, but have shown benefits with high torque servos in any application smoothing power delivery. I'm not sure that it will solve the problem, might be worth a try though.

If the twitching also occurs while sitting and powered up, I would swap the servo leads (steering and throttle) at the receiver. If the twitching goes to the steering and the throttle is OK, it's a bad receiver. If the twitching stays with the throttle, it's a bad throttle servo.

That's a good way to test never thought of that lol, thanks
