I think the ideal bomb drop system would allow the doors to be closed and a latch keeps them closed. to drop the load release the latch and let the doors free fall. Then have a servo that just pulls them closed.
This design could be accomplished by using strings on the doors to close them and a latch that the servo arm releases by rotating down also making the strings loose. This would allow the doors to work with one, pretty small servo but could carry a pretty heavy load.
I have 2 skinny doors on this one and I have not really given any thoughts to closing the doors, since each door is 8 inch X 1.25 inch, I was thinking letting them dangle... If you know this may be an issue, advice welcome.
I was basically going to put a loop in the center of both doors that a rod would just pull out of and let um swing. I have the dang manual here somewhere <it was a print version> and I am sure it has detailed instructions <grin> that will walk me through a simple install and configure.
