Took advantage of the light winds to stretch the BB0 out a bit.  Nice long straight boost put it way up there.  Arcing over, still nose up at ejection.  Good chute, long time coming down.  Landed on the field, shortish walk, no damage.  Nice!  This rocket has always had a "tight" motor mount, and today I could not get the Estes E9-6 to fit.  I finally peeled the label layer of paper off the motor to get it in the rocket.  Post flight the motor was extremely hot and the outside layer of paper was charred and smoking.  Obviously not much margin for containing the heat on that long of a burn
