I've been using them to light my E6 RC loads for a while now. The longer leads will definitely make the Q2G2 a must have in my range box.

And I used half of the orange sleeve to insulate one of the igniter leads, as the blue insulation ended still inside the nozzle.

But it was instant on at ignition.

I don't think I'll EVER buy any other igniter, at least for any MR motor.

Another FVR member used one in a D21 after the copperhead popped. Again instant ignition.

I also burned up a VERY OLD E16-4 that ended up being an E16-8 and ejected just before impact of my Warthog. That motor was just too long for the Q2G2, so I used the supplied copperhead, and was very surprised when the old, slightly swollen propellant grain actually ignited. But when Bill releases the 8" leads, I'm sure those are going to work great in the larger composites.

Several years back at one of our club (Challenger 498) launch, a young rocketeer was having trouble igniting a reloadable (I think it was a G64) with a copperhead. Tried it like three times with no success. I happen to have a few of the QuickBurst Hot Shot igniters in my box (they're very similar to the Quest new igniters), and told this rocketeer to try this.
The G64 ignited on that very attempt.

A guy on a blog somewhere recommended getting those LED replacements from superbrightleds.com; however, I've discovered they are also used in pinball machines, and this supplier:

http://www.centsibleamusements.com/...-led-44-47.aspx

has a better deal on them than superbrightleds.com does.

Disclaimer: Haven't tried them, don't know how well they work.

OK, I had some PayPal money laying around, so I ordered 20 of the red ones. I will try them out and see if they work OK (i.e. I will check out the current at the igniter end with different power sources such as 4 x AA or car battery and also if they fit the Estes controller easily).

If they work, fantastic. If not, I can always unload a few on eBay or give them away as freebies with other items.

Thanks, Fred!
Please let us know if they work! I'd like to modify several controllers.

I've already tried out a red led from SuperBright LEDs on my Estes launch controller and an Estes igniter. It works, with 4 AA batteries.

Did you meter the current when continuity is being checked (or try it with the Q2G2 igniters)?

Sorry, I don't have an ammeter. I just tried it with a Q2G2 igniter and the LED draws enough current to forestall ignition. The batteries are fresh enough to ingnite a Solar igniter.

If it shows continuity without blowing the Q2G2, that'd be all the test we need.

What part number (on superbrightleds.com) did you purchase? It'd be a good idea to have the information all in one place.

The red LED I used in the Electron Beam controller is: BA9s-R4 Red LED bulb. It's the 8th one down on this page: http://www.superbrightleds.com/cgi-...uct=755#BA9s-W4

It costs $1.98 and draws enough current to prevent ignition of solar and Q2G2 igniters.
