20180429_171223-1.webp MY REDCAT RAMPAGE XR STEERING SERVO STOPPED WORKING so I sent for another. Same. After installing it, it ran a bit and within half of an hour, it locked to one side, and won't budge. It stopped working, dead. The eBay seller offered a replacement: same kind: Redcat-Racing steering servo. Same fate: it stopped receiving signals. Dead. The seller was kind enough to refund me.

I then bought another steering servo: a Track star fifth-scale steering servo, installed it and began to rip around my backyard track. Then just like that it stopped working and the vehicle was running straight off a bend. No steering input. It stopped responding to steering-wheel input. Then after a few minutes it kicked back into life. This keeps happening on and off.

So, I trouble-shot the receiver. (Maybe there was something wrong with the channel #1 slot on the receiver.) I plugged the throttle servo into the steering channel, and then I rotated the steering wheel left and right. The throttle servo worked excellently. For good measure, I plugged the steering servo into the throttle channel, and worked the trigger to and fro. The steering servo worked a bit, began glitching and then stopped. That told me that it was not a servo issue, that IT WAS THE STEERING SERVO.

Then I began to wonder if the problem was my FLYSKY FS-GT3B transmitter?

I have contacted eBay and requested a return, but I'm not sure where the problem emanates from?

Is it the servo? The reveiver? The transmitter?

CAN ANYONE SHED SOME LIGHT?
 
Could be a bad pot on the TX, saw that a number of times during the two years I worked as a service tech at the LHS.

Try moving the trim when the servo stops and see if the servo responds to trim.

I did EXTENSIVE research and came upon a guy with a somewhat close issue of servo-glitching. One of the things he tried was attaching FERRITE BEADS to the wires of his glitching servo. I did the The same: I took the ferrite bead from my killswitch cable and attached it to my steering servo wires. Then I filled my car's tank and ripped until it was empty, AND NOT ONCE DID THE STEERING SERVO GLITCH OR CUT OUT!

I think I can say, problem solved. And thanks for your suggestions of help, Guys. PEACE!
