I have this random Issue when flying some nights, One night I fly ok and the K4 does quite well, But recently the Plane has been doing some strange things when flying.
Sometimes it goes straight into the ground or other times it flys right into Hangers etc, Take last Friday for example, I was flying in the MA and decided to get a Bottle of Guiness and a Jamieson chaser, One minute the K4 is flying fine and the next it went all over the place? This erractic flying got worse after a few more Jamiesons, I'm sure it's a bug in the system somewhere.. I've checked my Joystick and the calibration looks ok?
