This was supposed to be an entry for a folding plane challenge. The problem is, this is a failure, it can't actually fly - the hinge rotators aren't strong enough to hold the tail in place when this is in the air. Still, it's an interesting failure, so I'm sharing it as an experiment.

Instructions:
The jet engines are on activation group 8, so are on by default.

To fold the plane, activate group 1 and move the VTOL slider up to the top. This folds the tail up and rotates the main wings. Next, activate group 2. This will fold the wings back along the body. Finally, deactivate groups 1 and 2, return the VTOL slider to the centre, then activate group 3. This activates the car engines to drive the wheels (throttle for power, yaw to steer) and the tail turret (use the VTOL and pitch sliders to aim it).
