Hi, I have an old Estes Phonix that was always a contentious flyer ( especially on Estes Motors ) Needed a lot of umph and a very short delay. Recently pulled from the closet and added a section of body tube to lengthen to make it fly better in the wind... that created a payload section. Then modified the motor mount to take an E-12. Flew great on the E-12 except the delay was too long so I went to a 4 sec delay. Before flying it I had the opportunity and idea of putting in a new Eggtimer Apogee to give a positive deployment at apogee. Fits perfectly in the Payload section right under the nose.
So... off I go flying last week end and NO JOY.... . Flew reasonably well using the redundant 4 second charge on the motor... but 3 separate flights with no Apogee deployment. It preps on the pad ... ready to fire ...cricket chirp... then is still chirping when I recover it. Bench test in vacuum chamber and it works perfectly.... 3 5/32 holes in body tube???? Could the rocket be accelerating too slowly?
Any ideas?
