Piston System Kit
The operation of the piston system is quite simple. The piston sits in the airframe "over" the motor and "under" the parachute. It is attached to the motor mount via the nylon strap which is epoxied to both the motor mount and the piston itself. When the ejection charge goes off, the pressurization between the motor and the piston bottom pushes the piston upward, which separates the rocket and pushes the chute out. That`s all there is to it. No special prep needed, nothing to do...just push in the piston, load the chute, and you`re done.
First, I want to say that the piston system isn’t for all rockets. Cardboard rockets and dual deploy rockets I would rather not use the piston system. Cardboard doesn’t clean up well, alcohol soaks right into it. However, quantum tube and fiberglass are a breeze to clean BP residue after a deployment. I reiterate, the piston system doesn’t lend itself to dual deploy rockets where the electronics are placed in the coupler; you can’t run your ejection charge past the piston, though, you can easily use the piston system in the payload section to deploy the main chute.
