It would need some good motors and gearing I can tell ya. The solid wings with brass reinforcement weigh a ton on this model. On the extra's disc on the blu ray set they talk about how they had to make the wings hollow to keep the weight down for the Mech. That's why you see the warped wings at the exhibits today.
That's why I need the model in front of me, the motor is the trick to making it work.
I wouldn't use the model for mounting the motor, I wanted to use an aluminum plate and attach the entire mechanism to the plate. Including the wing pivots, attach the plate to the hull and use the plate for the mount.
The motor would be a gearmotor(they come in all shapes, sizes and torques), two gears are needed(one is attached to the motor), the other is moving the opposite way. For connecting to the wings I would use timing pulleys or chains. One connected to each gear, so the wings would move in the correct direction. And if set up correctly the wings movement will sync no problem. To stop the wings in each direction I would use a limit switch(only two needed on one wing), then use a 3 way switch to control the direction of the wings, the limit switches stop the wings from moving any further(thus damaging the model). Use a pot(variable resistor) to control the wings speed.
I know this doesn't sound very easy, I'm used to things being more difficult.
Getting it all together is the tricky part. It would have to be relatively precise, like I said, I would need the model to make it all fit.
