Animation Progress and theory of flying machine movement

That thatb the setting is done, I can focus on the movement of the biped and the flying machine within the animation. From the design of the flying machine, it would seem that the biped would have to move in a certain  way for the flying machine to move its wings. From looking at the design, it would like the biped would have to pull his arms and legs in when it wants the flying machine wings to go down and then have its body flat out if it wants to get the wings to go up. This certain way of movement will be interesting to see and entertaining when it flys the flying machine in the wrong angle.

Here is a screenshot of working on the animation of the biped grabbing one of the handles on the flying machine.
