Adolfo Camarillo High School rocket club flying an M2020 I max. Was simmed to Mach 2.5 and 35,000 feet. They didn't recover the booster, so no verification of actual performance.
My all carbon fiber rocket (the left) going up against Jared's fiberglass rocket at the National Sport Launch on the Lucerne Dry lake bed. Simulator said 7500 feet @ Mach 1.28 I believe it was somewhere around there but i cant verify it because there was no electronics on board. I did end of finding it a half mile away!
