Launch Report: P-40 Warhawk Model Rocket

Background
This is the maiden launch of this rocket
On Site Preparations
I used a Nomex chute protector for this rear eject spool design.
For a parachute I used a 28” Nylon chute.
This launch used a E20-4W Composite motor. This is Aerotech’s “White Lightning” propellant.
The supplied Aerotech igniter was used.
The rocket was slid onto the 5/16" launch rod and the controller wires were attached to the igniter leads.
Launch
Wind was out of the East and was about 4 mph at the most.
John stated the sky was clear - launch site was clear and did the countdown: 5-4-3-2-1. Teresa pushed the button on the launch controller.
The motor ignited and the rocket leaped off the pad. It flew stable, deployed the chute, and was recovered 329 feet West of the lunch horse.
Condition of rocket after the flight
The rocket was uninjured and in-flight ready condition.
Conclusions
This rocket has a calculated stability of 0.002 calibers. With the base drag hack it has a calculated stability of 1.04.
A string swing test was performed and the rocket passed that test.
What I learned
This was an awesome flight. Straight as an arrow up, and a nice gentle recovery.
