I didn't watch any video to install it on my INVADER model. Just a little tape here, a little there, and voilà. My only question is how to recharge the battery. Do I have to unscrew the container and replace the battery? What kind of battery does it use? If it is rechargeable, how to recharge it.
The night flight battery pod is not rechargeable. It should last about 3 hours continues which is approximately 18 flight's. You can replace the battery your self, these are 3X alkaline button cell - AG5 L756 there are available in most hardware stores or pharmacies.
