Two new drones with the same error? That is really strange but am glad that you are satisfied now and the third drone doensn't have any issues. Safe flying!

Thanks.  Similar errors.  First had a power failure in sport mode and dropped like a brick.  
Second one did a vertical take off after a few seconds in sport mode.

Thankfully my replacement seems to behave well but i must admit, I am very cautious now.  I need to get over it and get lots of practice.

Replacement arrived.
Tested and behaving normally.
Finally, after two faulty drones time to start flying.

Many happy landings with your replacement craft!
