I was running my less than one month old merv today, one 7.2v nimh, when suddenly it stopped. I noticed the esc and reciever lights are rapidly blinking red and green with no pattern. Pressing the button on the esc does nothing while the transmitter is on. When I turn the transmitter off the lights go back to normal and im able to turn the car off with the button rather than just unplugging the battery. Any suggestions?
