This is how I'm planning on mounting the thing... The binding post is where I will attach the e matches for deployment, and the wire goes inside the coupler which connects to deployment channel. I'm not sure if this will work.

I soldered a toggle switch to the deployment power, and the toggle switch will go on the bulk plate where I can turn it on by removing the nosecone when the rocket is on the launch pad, then putting it back on. I don't know where to get that fancy rotary stuff that I see a lot of people here use...

The switch only turns off deployment power... main power can't be switched off unless I remove the battery.

I made it so that it is in the main chute compartment, meaning by the time there's an opportunity to bump it the main chute will have already opened.

It was all I could find at radio shack.

The other problem is I don't know how to drill a 1/2" hole into fiberglass. The stuff already eats drill bits, and drilling 1/4" hole was already such a struggle.
