I've been working on a hot wire chute release widget based on an Eggtimer Quark. I'm through bench testing and nearly ready for flying. As is, it fits nicely in BT60. If I used a different hot wire connection, I might be able to slip it in BT55.
Here's the Quark. Jumpers set to 300'
Tucked into a BT50 nose cone base and coupler.
24mm engine tube avbay, 2S 180mAH Lipo and other bay end cap. The tubing is wrapped with a 3M fiberglass tape for some heat protection.
Power end all closed up. No switch for this version. Just plug and pray.
Release band. The cuttable link is 10# fishing monofilament tied across the band. It's wrapped with a nichrome wire. The band is doubled, then stretched around the chute and avbay. It's also tethered, so I'm not littering rubber bands across the landscape.
Chute wrapped, hot wire connected. This Quark has a custom 2 second firing duration. Now that I have a solid connection to the nichrome, it really lights it up.
And finally, the Quark and Eggfinder pair.
