Could I use a Quark to trigger a simple circuit like a hotwire deploy method? The rocket would use motor ejection for drogue deploy, the rocket splits in half with the nose and parachute compartment hanging by the coupler. Quark triggers deploy channel > resistance wire heats up > cuts nylon...

Merry Christmas DavidMcCann! (Anyone can reply, pass it on to someone)

Since I can't post my EX project here (It is at Rocketry Center though), I will post development of my live test stands. I also invite anyone else to post about their live or static test stand, homebuilt or not. More to come... (Loadcell attached to anchor plate, 1" thick milled steel...

Could propellant types be mixed, ie, (aerotech) black jack and redline, to create interesting smoke/flame pattern or thrust curves? BuiltFromTrash

Has anybody ever built a transparent rocket?? BuiltFromTrash

Come and post the best rocket videos that you have seen! Here's a few to get started: https://www.youtube.com/watch?v=rvDqoxMUroA https://www.youtube.com/watch?v=5wpmPgUQ0X8 https://www.youtube.com/watch?v=0qzOzjRJpaU I thought that the bottle rocket was really cool.:p BuiltFromTrash

Looking for new/used Aerotech RMS-29/40-120 Hardware and new/used Aerotech RMS-24/40 Hardware. Trying to get into higher power engines particularly reloadable engines to advance in rocketry. Thanks, BuiltFromTrash
