Flight Log - 2012-09-01 - Rich DeAngelis's Bullpup Iris

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’.
