I bought an unopened box (8 4 packs??) of B4-3s from a fellow rocketeer a couple years ago. They are -awesome- in the original scale Estes Blender, or my mini Photon Disruptor.

I have a 13mm based downscale of the Little Beth X2 that I've tried a longer delay in - but I've had poor luck staging recently - it keeps blowing out the booster motor mount. I only had 1 B4-7. Would really like a couple more -5s or -7s.

I fly them at Bong. Once the WOOSH sked is posted for the year, I apply for the Expired Motor Program permission for all the launch dates. (Yes, I note it on the flight card, too.) The staged one was flown by a friend at a TWA launch as a research flight. A 3xA+B research flight :-)

I've had no delay troubles. I've been counting them out, and they seem run about a half second long. I also notice that the smoke is thicker, yellower and distinctly more sulfury than current motors.
