It's Throwback Thursday, so here is a blast from the past. This is the Estes Partizon at the National Association of Rocketry's National Sport Launch hosted by FLARE and SMRA in Almagordo NM. I'm estimating from the flight simulation that the Partizon got over 3000 feet. I trimmed the parachute ejection delay from 14 seconds down to 11 seconds based on the simulation. Jolly Logic Chute Release was used to allow the chute to inflate at 400 feet. I used the Aerotech H135-14a White Lightning DMS motor. Don't worry, I'm certified for this.
