Flight Description:
Sub-optimal flight.
First attempt saw brief smoke from the nozzle then a spit igniter (FirstFire Jr. igniter). Pulled the igniter and installed a new one. Had to guess at the installation depth since the first attempt burned away the tape at the top of the propellant grain that is installed at the time the motor is built to ensure the igniter is not installed too far into the motor.
Second launch attempt again saw it slow to ignite/come up to pressure but eventually got off the pad. Next series of events were quick, but it appears that on the way up the ejection charge fired.
