This is the standard Estes Bullpup 12D kit, modified with a small payload bay between the forward fins and the nose cone, and a engine mount pulled slightly rearward to allow for a metal spring-clip for the motor. It is internally modified with a Kevlar shock cord mount and a much longer shock cord.

This was the first ever flight of this rocket. When I completed it, I was surprised it was so small yet weighed so much. I suppose I was in denial just how heavy it was and how much that would affect performance. Still, to be on the safe side, I skipped the recommended A8-3 and moved up to the B6-4. I’m glad I did.
The motor lit right up, and the rocket went nowhere, maybe 4 inches up the rod. The motor clip caught on the clothespin used to hold the rocket above the blast deflector. After about 5 seconds, the chute popped and the whole thing was over. Such a waste of a good B6 motor. Failed flight. That was the 13th launch of the day for the club. Just sayin’.
