Mark then demonstrated his EX motor building skills by launching his homemade, single use H motor. The AP motor was estimated to be an H150 and performed perfectly, though parachute deployment did not occur. Fortunately, the rocket fell horizontally, spinning all the way down, and suffered no damage on impact. Grumpy that he couldn't get a chute out, Mark launched his glassed Estes Sidewinder using an F24. Deployment was at apogee for a perfect flight and recovery. Finally, Mark launched his Arcas using an Aerotech J135. The 4 inch rocket lifted majestically into darkening skies, deploying a drogue at apogee and the main at 400 feet for a perfect flight. Max altitude was 2,800 feet.
