Original Design:
Here the piston would be mounted on two bracket and hold the drop arm to the body using a 1/4" aluminun shaft. To release the arm from the body the piston would pull the shaft from the drop arm with about 27 N of force.
Here the red part were replaced.

New Design:
This design push with 36 N instead of pulling with 27 N, it also is more compact saving space and eleminates extra pieces
the trigger for the drop arm module is the sol. a simple plate hold the arm up until it is in position to fall.
and the end result a tested and working piece
