email and noticed it. The T8VTT looks really good. Thanks for sharing
the design. I have a number of 6' T8 tubes sitting around and would
like to experiment with them. I might have a go building a similar
deployment mechanism based on your one.

Glad the assembly gave you some good ideas. It's kinda the outgrowth
of several things I've been working at. The extending plunger design
is something I've slowly improved over time, The syringe triggering
grew out of an idea Richard W. once mentioned.
Made the Chute yesterday from a 1'square section of plastic shopping
bag. I just used some magic tape to hold tucks in the 4 corners;
forces the square into a dome shape. Braided fishing line is secured
to the darts as shrouds. Takes like 5 minutes to make that Chute.
Was a tricky plan to get it all to fit inside T8 and still use a
minimum length of extra fuselage. I tried to make the frame barely
longer than the altimeter. I'm guessing the 6' T8 is about the perfect
length for these wrockets by the way. I used about 5' for the
pressure vessel this time. 2 gift cards cut in half become 4 fins
Haven't launched it yet... was running sims on Clifford's site, and a
full bore 21mm nozz was showing the highest apogee so I am gathering
up materials to build that internal release design launcher. I figure
I can trial it with that and a Gardena nozz to see if the sim has it
