My carbon fiber rocket with GPS transmission from t' prototype G-wiz avionics bay screams t' Mach 2.17 on a CTI N2850 motor, arrr, reachin' about 33K ft. It was a perfect flight, with computer deployed airframe separation at apogee, and main parachute deployment at 800 ft. T' GPS readings show us hittin' high winds aloft as we drifted back down through 20K ft., which took t' rocket horizontally at 55 MPH. Begad! But that luckily brought it back closer t' t' flight line for an easy recovery.
