Levity aside, the E26 motors have been a headache for me. I don't know about the other Q-Jet motors, but three ignitors per successful launch is not sustainable.
If anyone has been able to get reliable ignition of the E26, please let me know your secrets.
Yes, I lightly scrape inside with a paperclip to remove oxidation, and, I get the ignitor all the way in. I have tried "enhancing" the ignitor by wetting with thin CA and immediately dipping in black powder. I have also tried securing the ignitor by plugging the nozzle with removable adhesive putty.
Until I get this figured out, I will use the more expensive E6 reloads. I would prefer the convenience of SU.
At least I haven't had one of these blow up. I had an Estes E12 CATO and destroy a rocket this weekend. (Yes, Estes is sending replacement motors and rocket kit.)
