Third flight, first time using altimeter for deployment. Also left the long delay and ejection charge in the motor for backup.  Nice boost, fast and straight, just arcing over at the top of the climb. Good deployment of main chute at apogee. Long walk, grass landing, no damage. Nose cone shifted in body tube but did not come off.  I had also connected an E-match to the "main" deploy channel set to fire at 500 ft and it lit as planned.  Ready for dual deploy.
