Servo causing total powerloss?
 

hi all, really need advice,

over the last week my truggy has been causing me some frustration, first the ESC stopped functioning so I replaced it with an Orion 1/8 ESC, was out bashing today and the truggy would stop responding. Power was on, the ESC's fan was running and if I switched it all off and back on again it would work for a few seconds then stop. On closer inspection the receivers light goes out / flickers during the issue.

If I remove the servo from the receiver everything else works as expected. Could the steering servo cause such a problem?

thanks.

Yes, the steering servo can overload the ESC's BEC (Battery Elimination Circuit). This is a circuit meant to power the servo. I had a similar issue and stepped up to a Futaba Transmitter and receiver to take care of it.

Some people will add a separate BEC circuit that bypasses the ESC and reciever to power the servo directly.


You can also add a "Glitch Buster" to help take care of the problem.

thank you for the quick response.

I might go looking for a "Glitch Buster" not to solve my problem just because of the cool name :D

Its also possible the servo is bad. They do fail in that manner occasionally. If the problem occurred only recently that might be the issue.

I've had this exact same issue. Every now and then, the servo would work and the car would be ok, and then all of a sudden, the servo would not work. Sometimes the whole car, esc and everything would shut down. I tried using a receiver capacitor, aka Glitch Buster, and that still didn't work.

Turns out the wires inside the servo were torn and were no longer connecting with the servo board. It would also short itself, which was causing the random shut downs.

I resoldered the wires to their respective slots and everything is perfect.

I run a separate life battery unregulated direct to the Rx.
