HELP NEEDED: Multi stage dropping

Hi people,

We are trying to make a dropping mechanism for our plane which involves the following sequence

open door ----- (delay for half a second) ---- release latch (drop bottle) --- (delay half second) --- close door.

were trying to get the above sequence work on the flip of a single switch. Cant quite figure out how to do this. Could I get some ideas ?

the sequence descried above is in the video attached.

PS. were using pixhawk, trying to program aux channels to control these servos. Were trying not to mess with the arduplane source code as it might mess up the scheduling.

The video demo was done manually.
