It's very hard to guess.
Both the aircraft and the batteries were bought last year NovemberConsidering you might have tried all of the above, the only other thing i can think of is that your Battery might be compromised and the intelligent flight might not be working 100%.
How old is the battery ? Have you updated them ?
I have only had this hover drift once and it was a bad battery that would not let it hover niclely.
Still no answer without the logs. The answer and solution is in there. Please try. We are also interested in the Why. It’s how we learn, from others mistakes or successes. ✌Both the aircraft and the batteries were bought last year November
It sounds like the OP really isn't interested to find out.Sounds like you might be in ATTI mode... Check switch on front left of controller. Make sure it's on P
