I've only flown this motor a couple of times a few years ago. It was in a BT-20 model. The motor blistered the paint on the rocket around the motor.
I flew a D10-3 yesterday (new pack) and the ejection charge burned the BT20 stuffer tube clean in half in front of the motor. The casing itself was solidly stuck in the BT20. I had to use pliers to get it out of the remains of the model. In this case, the BT20 was not blistered where the motor was located, just burnt to a crisp in front of the motor. The delay also seemed a lot longer than 3 seconds.
So my question is, have others had these kind of issues using this motor in a minimum diameter model? Maybe I am missing something. If this is a general problem with this motor, I don't see how people can use it.
Thanks,
Don
