Q2G2 3.5 Igniters (6) HAZ

These starters/lighters/igniters are fantastic and are very versatile. I have used these in clusters and they have never let me down. I find them to be easier to use than the Estes Solar igniters in clusters since the wires are a bit more flexible and don't tend to shift the pyrogen end around as much. They are also fantastic for use for dual deployment. The only drawback is that they use so little current that a standard estes launcher will light them up when you insert the key. As a previous reviewer has mentioned swapping out to a LED will correct this or use a different device to launch. Price/per is outstanding and they are extremely reliable.

This is the best, most reliable low-current igniter available today. Firing current is about 125 MilliAmps-about 1/10 the current required for Estes igniters. Can be fired easily with a 9 volt battery. A word of caution: Do not use these with any launch controller that has a light bulb for continuity!! Most light bulbs will draw enough current to fire the igniter. You need a launch controller that has a continuity LED. LEDs will only draw about 25 mA, giving you a wide safety margin. These are not only good for ejection charges, but it's the only igniter I use for clustering. Be sure to wire the igniters in PARALLEL for clusters. They ignite about 3 times faster than Estes igniters, which is both a pro and a con. On the pro side, they will fire before the rocket leaves the pad. The con is, these igniters not only fire fast, they burn fast, producing more of a pop than a sustained burn. On some aged Estes motors, I have had the igniter work but the motor fail to light. If your motors are not too fresh, it seems the propellant gets a thin oxide film on it that can make ignition more difficult. The next time I do a cluster, I'm not only going to test continuity beforehand, I'm going to use a small drill bit to abrade the propellant a bit and create a fresh ignition surface. Another trick that will help is dipping the igniter into one of the pyrogen compounds that are available.

Q2G2's for Cluster rockets are fool proof. I have launched 2,3,7 and 12 motor clusters using these igniters with no problems. This was done on a 12 volt power supply. All in all with over 250 flights in single and clustered motors not one has failed . It doesn't get any better than that.
