Hi

Today i prepared my Xray for some racing, i 've inserted the batterys at home and checked some settings.

Everything was fine and i switched the ESC off, and placed the xray in the trunk of my car.

Arrived on the track i took the body off and switched the ESC on but nothing happend.

I' ve tried a pair of other batterys, but the ESC did also not work!

My first idea was a broken powerswitch, but the switch is ok, also the wires and RX-Plugs are fine.

Is there anything else that i can try? Or is that the end of my Mamba?

The funny thing is, i can still connect with castle link

Greets Hi-Fish

Try doing an update with your computer if you have the cable. That has happened to me before. Also you could try this:

Unplug steering servo. Hold throttle wide open. Plug battery in with switch on. Hopefully it should beep or make some noise. Then put to full brake. Noise or beeps. Then return to neutral. See if that helps.

Sometimes the BEC section of a speedo will quit, try a receiver battery to see.

Try putting a needle through the switch wires and see if it turns on. This has happened to my castle before.

Hi Dave

You were right, with a battery pack on the receiver the Mamba works

But there is not a lot of free space in the car, i think i will buy a new ESC.....

Thank you

You could just buy an external bec as well. About 20-30 bucks.

I'd call castle about it. They are pretty good about taking care or their customers.
