Chosen Solution

My AR Drone 2 has crashed into water. I put it for a week in a tight plastic bag with some rice trying to dry it out. However, seems something went seriously wrong as when I connect the battery it didn’t respond at all. Now, first how can I tell which part has been damaged? second: what is the best way to fix that? Many thanks

Putting it in rice may have ruined it. Its food not a solution. Find someone that does micro board repair.

I have faced the same situation when my DJI drone has fallen into the water. I have tried some basics steps at my own risk.

  1. Turn the power off and remove the battery.
  2. Check your warranty: If your drone is still covered by the warranty, there’s little more than you can do except put it in a dry, warm and ventilated place until you can send it off to your supplier or ‘best drone repair shop for DJI Drones’
  3. Towel dry the rest of the device.
  4. Put the device in the oven at the lowest possible temperature, 125F to 175F, for several hours. This will dry any remaining moisture in the device. Do this as soon as possible. These temperatures are above the 104F that DJI recommends.
