Default Servo problems?

Ok, I just got into on-road this past week, and I had some major electrical problems at my first race yesterday. Running a spektrum radio, with a novak gts speedo. Jr9000s servo for steering that I had pulled from my truggy. We figured out that the problem was the servo, which was drawing too much power from the reciever, sending it into failsafe mode. I put in a different servo when I got home, and everything worked like it should. Was the servo just too much for the bec to handle? I really like that servo, but if it won't work, I guess I will have to sell it.

Digitals tend to pull more power when running Spektrum this can be an issue. You may need to run the Spektrum Power cap or the one that Novak makes. I run digitals and Spektrum in my sedans with no issues but I am running a GTX.

the gtx has a6volt/3amp bec as opposed to the gts's 5volt/1amp bec.

So it is highly possible that the servo was pulling more than that.

I think the main problem now is the capacity of the receiver to give the right current to the servo..So with the Spektrum Power Cap this problem will be solved.. I've seen this with a lot of racers.

Uh, guys, the receiver doesn't give power to the servo. The ESC gives power to the servo. Your ESC can't handle that servo, simple as that.

Alright, thanks, I figured that the esc couldn't handle the current draw of that servo. I put in another servo I have, and I will be all set for next race.

I first put together my touring car with a 9000s and some old, used ESC I bought for cheap. The car was glitchy, and I burned my finger when I touched the ESC's heatsink. I used a voltage regulator until I upgraded my ESC.
