My Anafi takes off ok... But then.... Lands hard and flips to the front.
Props seem to BE ok and i Have not changed anything.
What can it BE?
You can see it on video
Clearly a lack of power due to voltage drop. I used to have a DJI Spark drone and they used to call it nyut-nyut, or hopy Spark.
Mine started doing the same thing at 2 years old. My logical conclusion was that it was a contact weakness. I disassembled the Spark, cleaned all the connectors (it has a lot of very tiny ribbon cable connectors) and after that all the faults went away.
It could be the same for the Anafi, or the battery could be dead (improper storage, many times it was fully discharged info here: What you should know about Anafi batteries).
