One of my more recent air brake rockets twice failed to deploy the blades, something relatively uncommon for my birds.
Here is a “hat” to put on the motor (which will also have a streamer on it so I can FIND it!)
The upper cylinder has a piece of aluminum can facing the motor’s ejection charge, the sticks are carbon fiber rods. The idea is the that ejection charge will be directed OUTWARD, so it should assist the rubber bands (which work 99% of the time, I think the displacers on the rocket are just too small and not giving enough leverage.
