It's embarrasing to have spent so much time and energy on a project you can't even come up with a creative name for. If you have any suggestions, please leave a comment.
Later today I will be flying this rocket for the first time in its two-stage configuration. This is the moment of revelation. Will it work?
I took the rocket to a MASA launch a week ago, and got some helpful advice. According to the manual for the electronics, a single 9V battery won't reliably ignite an Aerotech FirstFire igniter. The igniter requires 4.0 amps to light, and at 2.0 amps the voltage drops down to about 3V, and at 5.0 amps it drops down to zero. So to remedy this problem I added another 9V battery connected in series.
It is staged from a G64 to an E16. The entire rocket weighs pretty close to 3 lbs loaded, and the upper stage weighs about 1.5 lbs. The upper stage has at best a 2:1 thrust-to-weight ratio, but with an upperstage it isn't a big deal, since it can be considered as prolonging the coast phase.
