Hi Gerald.
No sorry, no pix of the pieces inside.. But consists of a rectangular balsa sylinder and ditto piston.
A rubberband in each corner are stretched once the sylinder i pushed back.
The leatherpads are wrapped on top of each other, with a hole in three of them. The fourth has a tiny loop, wich goes through all of them, and are secured by the little pin you see is hanging from the housing. Once the servo activates, this tiny pin is letting the loop go out of the three pads.
And pop, here we go..

When released, the chute pops out about 1,5 meter backwards.
The chute is also wrapped around a rectangular piece of 1mm polycarbonate plastic, to make it withstand the force needed to puch back the piston.
This piece is lost once deployed. No one have ever noticed it..
Thanks. glad you liked it.
