Long Startup Time

The motor took significantly longer to light than previous tests, including the second P motor test that used an identical igniter with significantly more propellant surface area. During static fires the igniter was retained by gravity until the motor had built up enough pressure to eject it. Video evidence shows that the igniter fell out of the motor within a second of firing.

Future efforts could faster-burning gas generators igniters (pyrogen or BKNO3), higher surface area propellants (pixie dust), or additional mechanical retention. While chffing chuffing represents a minor issue on this flight, successful, rapid, and complete ignition is a necessary technical milestone for multistage flight. Care must still be taken to respect the structural limits of the motor casenot over-pressurize the case or clog the nozzle with a large igniter.
