First ire Jr's??

Sorry to keep jumping in here...

I found a real good one at

He says it works well with RRC2

You want to use an e-match, NOT an igniter. There are a variety out there if you can find them. Giant Leap sells M-Tek's on occasion. Others to keep an eye out for are Oxral, Daveyfire, and others as well. Different characeristics too.

Thanks 😳

Personally, I use Daveyfire 28-B for the most part although I also have a pile of 28BR's... best ematchs going. Oxrals are also reliable. I haven't used Mteks very much in flight, though used them a bunch for ground testing to determine size of charges. all are getting seriously expensive at $2 each or more I'm hearing. Daveyfires are no longer being made. if you can find a bunch BUY 'em.

I was told just today that the old website for Daveyfires said they had a shelf life of "one year". Now that I think about it, my SSS had a Daveyfire that was dead as a hammer. I'd think those things would have a LONG shelf life, but I'm the village idiot on this sort of thing. How long would they last?

If anyone has some of them old, bad Daveys, let me know 😉

I've never had one fail that I know of, but mostly I use redundant matches and redundant altimeters except on altitude shots so it's entirely possible I've had matches fail. My SSS bird could well be buried 3' deep in the prairie due to a bad match (white wire, green cover Daveyfire)

I have been testing the 'christmas bulb' design and it
works wonderful.

Simple and very effective.

Used my RRC2X on out-put test mode and tested with
a rocket mock up.

I am gluing the bulb assy. into a piece of 3/8" plasic
tubbing then slidding the other end of the tubbing into
a plastic quick connect fitting. The fitting threads into the
alt. bay, the wires then pass into the bay.

I'm very happy with the results.

purchased some from the internet.

still fits in same holder.
