Comments
The ejection charge did not ignite and we had a lawn dart, destroying the rocket and electronics. We fear the below freezing temperature caused the issue. We tapped the ejection casing to be sure the charge was loose before we flew. We blew out an igniter with a launch attempt, 10 minutes before the failure, and then went with a new igniter. The engine was purchased in December 2015 from Tower Hobbies or February 2016 from Wildman Rocketry.
