The premier igniters used to be the Quest Q2G2. Sadly, they also switched to the non-pyrogen formula. However, they use much less current than the Estes and even the new non-pyrogen version is more reliable than Estes starters (as they are now called). Even more sadly it seems all Quest igniters are very hard to come by. I believe there was some sort of production issue.I was using a club launch system using a car battery so I doubt the controller is the problem. Is there not some other brand I could buy? I really don't want to do the pyrogen dip myself if I don't have to.
This is exactly our assessment, as well, after hosting lots of large group launches since the new Estes igniters (or whatever) came out. Without guidance, visitors have failure after failure, but once we talk about, and demonstrate careful igniter placement, reliability goes up to nearly 100%. Igniter must touch propellant, and folks must be careful when manipulating the igniter and leads. If you want to bend leads, it helps to support them by holding firmly across the paper tape. It's very easy to cause invisible damage to the tip as you move leads, especially once the igniter is in the nozzle with the plastic plug in place.The new "starters" no longer have pyrogen on the tip. You need to make sure the tip of the ignitor is actually making contact with the BP.
Correct. See my previous post for an explanation.I have better success with the new igniter by pressing and staying on the launch button until rocket leaves the pad. They just don't have the quick flare up like the old ones. So stay on the button, don't bump it but press and hold until motor ignites.
Ummmmm, I wouldn't recommend that with straight CA as it can unpredictably "kick off" with an exothermic reaction and burn. If it does while dipping into a small container of BP..... KABOOM!!!One of our club members has had good results by dipping them in a CA and black power mixture.
Tango - We're showing our age, man. My range box still holds a straightened paper clip on a cord for this precise purpose. To go even further, I actually used this method on one of my recent launches when I didn't have a proper sized plastic plug. Old school rocketry, baby!I got out of rocketry before Estes started adding the plastic plugs to hold in the igniters, and before the change to no pyrogen tip, but one of the tips I learned while doing competition rocketry was to make a tiny little ball of wadding, and after inserting the tip of the igniter into the nozzle, carefully stuff the ball into the nozzle. It served pretty much the same purpose as the new plastic plugs, but it also held the tip of the igniter against the BP propellent, as well as keeping the igniter leads separated to prevent a short.
Yep, I just started getting some grey hairs this year, at 45 years old. :wink: Another plus to using the wadding is that it's biodegradable, not so sure about those plugs from Estes.Tango - We're showing our age, man.
