power... and charger...

I spent some time during weekend to find battery LIPO pack. I didn't order it and need more time to understand this part of drone. I feel this is one of the most complex part of quadcopter, you can not choose correct battery if you do not have charger for it. In my case I have to buy 4S battery and price good charger exceed battery :(. I didn't know about it before. So finaly I need to by battery + charger + box to keep battery safe if unused. Hope will find a time during week to complete it.
