ESC issue

[92fox]

Having an issue with my stock ESC that started today. Took the rig out to play, and out of nowhere it would go slowly in reverse with no throttle input. I took the body off, and tried to turn the ESC off with no luck, so I unplugged the battery. When I plugged the battery back in, the ESC blinks rapidly with the green LED.

The manual tells me that this means the ESC is not getting signal. I checked the wires from the ESC to the receiver, and all are good. All other servos work fine. Battery is good. Batteries in the transmitter are fresh as well. I've checked the neutral setting on the controller, and its in the normal position (50/50). I've never touched anything in the menus before, but reset the transmitter and end points to be safe. No luck.

Is my ESC fried?

Try rebinding you radio to the receiver. Basically your TX isn't talking to your RX.

I'll give it a go

That didn't work either, but thank you.

The transmitter and receiver seem to be talking on all channels except the on for ESC, as all other channels perform as they should.

Try switching your servo plug and your esc plug in your receiver and see if your throttle will operate your servo, if it does you can be pretty sure it isn't your radio. If it does work, check your esc plug and wires going to the RX and see if that they are all intact.

I had the same problem and found the receiver was defective. On my Spectrum receivers there is a tiny orange light inside that was not on. Replaced the receiver and all is good.

CODYBOY - Tried that this morning, with no luck

penguin - Is there a way to verify it's the receiver? I'm still a relative noob to all this.

I tried the ESC on my Slash's receiver this morning with the same issue. Also tried all other servos in CH2, which is for the ESC, and they all worked. Leaning towards the ESC being the culprit, but still open for suggestions.

Thanks for the help so far guys

If you have a known good receiver just install it in the culprit vehicle. That will tell you if the receiver is bad. Don't even have to remove it from your other vehicle. Just plug everything from the TRX4 into another receiver and see if things work properly.

Got it fixed...called Traxxas and somehow the throttle trim lost calibration. Spent a minute with the support rep on the phone and got her fixed.

Always!

I have to say, I am amazed how this thing has held up. I'm on all stock electronics. The only thing that broke from the factory was the servo horn, and that lasted a long time. I've had it for 5 months now, ran over 50 batteries (low estimate) through it with this being my only major issue.

The only things I have done to the truck are Proline F100 cab with Axial Honcho bed (custom diamond plate flat bed) with some scale accessories, SSD beadlocks with Proline BFG tires, and a Dravtech battery tray.
