Summary edit

Description

My carbon fiber rocket with onboard GPS transmission screams to Mach 2 on a CTI N2850 motor, reaching 33K ft. (final details to follow when I get the <a href="https://www.flickr.com/photos/jurvetson/5035200076">flight data</a> from the two G-Wiz avionics computers and the flight data from the ground station).

That’s a 10 ft. tall plume coming out of the tail. The motor has an accelerated burn from o-ring spacers between each of the six propellant grains.

It was a perfect flight, with computer deployed airframe separation at apogee, and main parachute deployment at 1000 ft. The <a href="https://www.flickr.com/photos/jurvetson/5239784773">GPS readings</a> show us hitting high winds aloft as we drifted back down through 20K ft., which took the rocket horizontally at 55 MPH. But that luckily brought it back closer to the flight line for an easy recovery.

Here's the <a href="https://www.youtube.com/watch?v=dygIlRFe8Jk" rel="noreferrer nofollow">launch video</a> compilation.

The only damage was to the vinyl stickers, which melted off.
