RE: GWs A10 EDf55's
The GWS A-10s, regardless of motor, all have ailerons and elevator control. None have rudders, unless someone separated them on the twin tails and found a way to make them functional without making the bird any more tail heavy. Some removed the landing gears to lighten the plane while others are having success with balancing with the gear, but limited control after gaining speed on take-off or on landings.
I don't know what video you are referring to, but A-10Flyr has good footage of his A-10 somewhere in these forums.
