I had at least nine flawless launches prior to this using a cluster of three C6-0 (plugged) motors.
It is a good thing the connectors I use as ignitor clips do not let go and it never got off the rod. It would have been a short flight and a landing in the weeds.
So now I have a 24mm motor mount and plan on using Q-Jet E26 motors. That is a tad less total impulse than the three C6 motors, but also less weight, so the flight performance should be about the same. Will likely need to move the battery aft for balance.
Frank should be happy.
