We’ve begun shipping our new Q2 'Generation Two' (G2) igniters. These are absolutely the best igniter we’ve ever produced. The Q2G2 is made from a pair of twisted and insulated lead wires with a welded micro bridge wire. They are very durable and are very well suited for cluster ignition.
The tip is virtually indestructible. The long insulated lead wires really help prevent shorts caused by the wires touching each other and… the lead wires are actually long enough that they sit outside (not under) the engine exhaust, so your micro clips stay clean!
You’ll need to use caution when using Q2G2. They are specifically designed for use with the Quest 9V launch controller. Other brands of controllers may fire the igniter when the safety key is inserted. This is because the all-fire current on the Q2G2 is very low at an average of 150ma. This is close to the same current that flows through light bulb filaments. SO BE CAREFUL and always do a continuity check with your system first if it is not a Quest launch controller.
Why make the igniter so sensitive? Simple… by far, the largest users of Quest rockets and engines are youth groups like 4-H and Scouts. Keeping the current needed to fire the igniters lower increases the success rate for launching. We’ve been doing this for twenty years now and by far the largest customer service issue has always been ignition problems. Most of these are tied directly to the type and condition of battery used (people tend to not follow directions and don’t use fresh Alkaline batteries).
If your hobby store doesn’t stock the Q2G2’s yet, they are available on the Quest website
