There used to be a video of a $22,000 1/2 scale Zero on its maiden flight on You Tube. It's been taken off the site and I haven't found it anywhere else.
It looks as though the ailerons were reversed. The right aileron seems to be going down, which causes the plane to bank left. To get out of the left bank, the left aileron needs to go down and the right aileron needs to go up.
Someone probably connected the servo leads backwards.
