Tnx for answer. In battery info in djigo4 app say that batter date is 9month 2019. So i asume that if update neded it will warn me by message. So im good to fly.
I got 2 new batterys for my spark. I charged them then turn on spark. And i got none update battery message. My spark is on lastest firmware. Is this ok or i need to do something manualy?
You are right. It didn't go over lake. I dont't like that feeling ''what will happen if it accidentaly fall in lake'' :) Over ground i got more confidence :D
