Brushless system problems
 

Hi. This all started when I removed all electronics in order to repair the 4wd. When I later plugged everything back in this happened. What can the problem be? The battery is a 7.2v 5000mah NiMh. When I try it with a 7.4v 5000mah lipo it starts up like normal but when you move the controls everything dies. I hope you understand. Thanx :) http://youtu.be/h5j1QPJQqOM
