HELP! I pulled my MA2 out of its case yesterday to go fly. Press the power.....nothing. The batteries are all showing full charges and the contacts on both batteries and drone are clean. I tried plugging it into my computer to see if it needed a firmware update. It did and I was able to update the controller, but the drone itself still wouldn't come up so I couldn't update it. Its been a few weeks since I last flew, and it that time its been sitting in its case on a shelf. Has any one encountered this before?
