I'm also going to add a drag chute. I've installed the drag chute fairing from the kit and cut and hinged the doors on it. I'm not quite sure how I'm going to open the doors and deploy the chute, but I have a few ideas.
Bob,
Here's some images from my scratch build chute release system for my DerJet Hunter. One servo does all functions, door release and then chute jettison, using a 3 position switch.
The doors are spring loaded to open, and are held closed by the pin, which also serves to retain the chute. One door overlaps the other and a hook on the top door engages the pin and holds them closed.
The chute needs some help getting out into the airflow, so I use a sort of 'trampoline', attached to the doors that lifts the chute up as the doors open. After some trial and error it now works well.
A motivational shot for you - make the chute work, it is well worth it!
