Worked fine.

Igniter wouldn't ignite with the 6 volt Estes controller

I was not able to ignite the igniter using the standard Estes controller (6 volt). I therefore couldn't get the engine to ignite. The controller is working based on a voltage check. Yesterday I was only able to get the igniters to heat if I bypassed the controller and used 9 volts with a 16 awg wire. I hope to try it this week with my son (who received the rockets for Christmas).
