I recently launched a 29mm SU on these ignitors, and could not be more pleased. I used a 6V system, yes that is correct. You can use the standard Estes control for these, knowing this saved me a ton of money in the long run. They do take a delay to fire, but so do all others. The only con is the price, 3 for $8 is a bit expensive, but for how well they work, I will take these anyday.

Fellow rocketeers tend to hate the old copperheads for their poor reliability. I found that if you just treat them gently, they work quite well. At my local club where it is usually quick and easy to change out an ignitor, I will usually start with the copperhead that is included with the reload. It would be too expensive to throw out the copperhead and use a First Fire in every motor. However, when I am at a big event and want the best reliability in my E-G motors, I will pull out the First Fire Jr. Nothing worse than waiting 30-45 min for the launch cycle and then have your ignitor fail. I have yet to have a properly First Fire Jr fail to light my motor. Well named.
