This is a test of my mechanism to raise the Blast Deflectors. It has some issues, so I need to make it more reliable or come up with a different approach.
The way it works is the styrene bar raises the three deflector panels by pushing them up, and then the deflectors drop by gravity. I may actually end up using paper hinges, because I need zero resistance for the deflectors to drop back down. The angle of the bar causes them to rise in sequence.
The problem with the twin motors is they get out of synch. The possible solution I found is that if the limit switches are on only one motor, with each up/down cycle they can realign, because the bar hits the motor on one side and is forced to a stop, while the other motor catches up and hits the limit switch. (I need to add a second force stop at the top of one thread.)
But I have a couple problems with this solution: 1) The motor on the right sometimes locks when the bar hits it and forces the motor to stop (I ordered small springs to see if that prevents the locking). Even if I switch motors, the locking still occurs on the right side, so it might be an unlevel platform or a slightly off angle (The threads have to be perfectly parallel). 2) I don't know if this forced stop for a couple seconds while the other motor catches up will burn out the engine.
I am using a boring 1/72 Trumpeter FLight Deck, but trying to add some details to spruce it up, and photo etch tie-downs.
