servo twitch

[v8thndr]

I have a Blue Bird servo for the throtle 89oz @ 0.06 sec. It works great for the throtle, but when I apply the brake it starts twitching or chattering! Is it the servo or is it an ajustment?

While there are numerous causes of servo glitching, you could have a dirty potentiometer in either the servo or your transmitter. My sailboat had dirty or corroded potentiometers (probably from water), and a couple shots of motor spray into the servo and my transmitter's right stick made all the twitching go away. The symptoms were similar to yours. One servo twitched as soon as I gave it any input from the transmitter, and the other twitched only when I tried to move the servo in one direction (like your servo).

Also make sure there's not some loose screw rattling or something when your engine is running.

I found the problem. I have an M8 radio W/DSM and I had the ABS on and did not know it. The radio is new to me. Thanks for the input.

Hey, ABS...that's pretty sweet. I don't have a fancy radio so that didn't occur to me! :)
