Servo engages when AP is on everything works but it just oscillates around the heading

you select on the AP and oscillates on the gps track as well.

I will try and calibrate it again and see if it is any better.

Hey Guys

need some help quick for a friend. He is flying a jabiru J430 with a Digiflight II VS autopilot, but when we engage the autopilot

to hold heading and alt the aircraft wanders around, it doesn't lock on the the heading or alt and hold it there does the same with gps

steer.

Any ideas what could cause it.
