Ive heard that Copperhead igniters are unreliable for igniting HPR motors. Is that true?
Many HPR flyers do not like the Copperhead igniter, prefering alternatives when they can be found. It is certain that Copperhead igniters are not a good choice for igniting clusters. However, some have found the Copperhead to be a reliable igniter for single-motor HPR rockets. From: dcrcep@mizzou1.missouri.edu (Elmer M. Price) Hi Folks: I have a comment on the reliability of Copperhead ignitors. Our small group has had no problems with these, once we figured out the best way to use them. So, in spite of all the negative comments, we actually really like these things. We have launched composites up to and including I-sized motors with great reliability. For example, two weeks ago, two of us (at the excellent St. Louis launch), launched two I284 birds, one I161, one I211, two H123 and a few F’s and G’s. We had 100% ignitor success. O.K. So what do we do to achieve such reliability? First, open the reload pack and assemble the motor in the usual manner. Second, find the Copperhead that ca
