Can't really see the drop in the video. Might be my computer.

Anyway, how does it work? Servo-operated hatch opening mechanism?

My concern is strain on the servo connecting a Rubber Band to the servo Arm.
I have tried this before and with the weight I was trying to drop it was to much for the Servo to handle the load directly.

For light weight load this looks fine. Good Job!

$4.99 each. It's ancient - recall fitting on to a model around 1983 or so when they were new in England. All you need is a small servo, there's no real load on it when it actuates.

Here's the way we do it. The "U" shaped plywood unit is an unverted "U" and the horizontal part has Velcro (white panel) to hold it on under the wing. The release pin moves through a ball point pen ink holder tube. The bomb is held on with a rubber band. The bombs are toilet roll inners, the weights are paper clips and the fins are cardboard off breakfast food packets. One bomb, left one, has a green milk bottle top, note, go GREEN, and the other a formed foam nose and streamer. The bomber is usually a Bixler.
