First thing is to relax. Easier said than done I know.

Now lets check the following...

First make sure the ESC connections are secure to the receiver.

Next make sure there are no breaks in the power wires.

Let's also check the servo wiring, make sure there are no breaks in the line.

Then check the antenna on the receiver, make sure it is standing up and not broke.

After that, do a google search for * ESC Lipo cut off on Exceed RC car, how to disable*

No, does the problem happen if you have the car up and you are right beside it?

or does it happen when the car is away from you a few feet.

Battery's in the controller are they good.

Go through this checklist and get back to us.

Thanks.
