The Jolly Logic Chute Release is becoming the standard for dual deploy. I noticed that when it is used, only the main chute comes into play. Does it make sense to have a drogue at apogee then the main chute at 500 feet? Does anyone use it that way?
It is certainly an option to use either a drogue or a streamer if you have a heavier rocket that you want to slow a bit more than just splitting apart with the contained main chute at apogee. Could help with visibility as well. The trade off would be how big a drogue or streamer and how fast/slow you want the descent to be.
My Torrent kit came in on Wednesday. It comes with a 12" drogue and a 36" main. The Apogee site lists the Torrent at 63 ounces. That's nearly 4 pounds which does not even include the casing and reload. This kit is heavier than my Standard Missile II.
I haven't started the build of the Torrent yet but eventually I will have to decide whether to use a chute release or the traditional black powder/altimeter method. I like your idea of streamer for visibility.
Someone replied to my post on the Rocketry Forum concerning the use of a chute release for dual deployment. He had a drogue chute deploy via engine ejection and the main deployed using a chute release. That could be the future of duel deployment. You can still put an altimeter in your e-bay to gather flight data.
