I was flying a quadcopter in mission mode and experienced a power loss for about 2,3 seconds. And dropped some altitude. After 2,3 seconds I was able to take the drone into manual control by the RC.
firmware v1.10.1 release. it’s not a customized firmware just stock.
This is the log. I was testing the quadcopter 6,7 times before for around 20 mins flights, nothing like this occurred before.
