No power

[London idiot]

Hi guys 4.6 going well suddenly cuts out won't start no battery power put in fully charged hump back no power. Unplug servos plug into another car no power to hole car put it's servo back every thing back on try other servo same thing. So can a bad servo take out the hole car and both go at the same time? ? Or am I looking for a another problem. The one's in the car are the original crap hpi.

I would look at on/off switch first, they go bad easily. then if not the problem then receiver,

Plug the battery directly into the receiver, that will bypass the switch, make sure to follow polarity of course.....
