|  Servo Causing issue with Receiver
So, I have a Spektrum DX4C and a Savox SC-0251 Yesterday, while wheeling on some rocks, the RC just stopped responding and the ESC started beeping like I was no longer connected to my receiver. After doing some troubleshooting, what I discovered was, while the steering servo was plugged into the receiver, the receiver lost connection to the remote. As soon as i unplugged the servo, I regained connection and everything worked, minus the servo of course. Besides the obvious, I need a new servo, has anyone run into this problem, and does anyone know what may have happened here? Thanks. Last edited by w0pgk; 04-07-2015 at 07:08 PM. |

You don't necessarily need a new servo, but you definitely need an external BEC to run it. Savox servos are a bit more power hungry and need their own power source.

RX's weren't designed to handle heavy loads from crawler servos. Wire the + from the bec directly to the servo. Wire the - to the servo and rx.

I just had a servo winch do the same thing to me. When it was plugged in the receiver wouldn't power on like a safe mode or something. As soon as I removed the winch everything worked fine. That was with the srs4210 receiver. I tried it with a different truck which has a sr410 receiver and as soon as the receiver got power the servo would glitch and start spinning and I had no throttle. Once removed everything went back to normal. I believe my servo winch got water damage and the pot went bad. In your case I would start from scratch, set all Trims to zero and rebind the radio/receiver together. Once that's done try plugging in the servo |

I ended up just replacing the servo. I may try to warranty the old one since it is only a month old. Still not 100% sure why it would have failed.

I would recommend one of these. Makes it easy and you don't have to worry about running too much power threw the receiver. Holmes Hobbies LLC |
