while taxiing my wings pop up and down. they go into the flight or flexed position then return normal every couple of seconds. mike davis

CONFIRMED:- Wingflex during taxi makes rapid jumps.

It's an issue they are aware about.

It will get fixed then. I did not know if it was my setup. Mike Davis

The 747X has that too sometimes - minor issue really :(
