Tell your 5000 closest friends Jerry Irvine sent you. That's important.

Hmm . . . No "Blue & White" wires . . . MJG claims to have an "agreement" with BATFE . . . I see nothing from BILUSOCN about being exempt . . . Does BILUSOCN have a website ? Dave |

Can we ever have a tech discussion? If rocketeers (users, manufacturers, associations, dealers) do not want igniters and propellants to be exempt, ATF and DOT and FAA sure as HE double toothpicks do not!! MJG is "pyrotechnic". |

Glad you added to the original answer. I've never used an e-match. I assumed they have always been pretty much the same as far as the design, but had no idea what compounds were used to enhance them.

Estes offers their pyrogen-free "starters," but I see that Quest Aerospace is back in operation, and that they offer "First Fire Mini Initiators" (AeroTech-made Tiger Tail/Copperhead-type igniters, see: http://www.questaerospace.com/First...06_3443224.aspx ) as well as their Q2G2 igniters (in both 3.5" and 8" lengths, see: http://www.questaerospace.com/Q2G2_...06_3443223.aspx ), and both have, I think, pyrogen-coated tips. Unless they're running an outlaw organization, they must have permission to make and sell real, bona fide igniters, which also work with Estes motors.

My understanding is Quest changed the Q2G2 formula as well and they are not as good as the original version. Unfortunately.... |

The Quest website has been redesigned. If you try to add the Q2G2 igniters to the shopping cart a pop-up reads: "Unable to add to cart. Product unavailable."

Figures.
I lost all confidence in brand Q when they announced with much fanfare the SU BP 29mm Thunderjet Motors. They apparently had many produced then had people test-fly them at various launches. They then proceeded to FAIL to bring them to the market. Thankfully brand E no longer announces products that have any chance of NOT making it to market. ALWAYS UNDER announce/promise and OVER deliver. Doing the opposite of that EVER has nothing but long and short term negative business impact ALWAYS.

I agree with GH about Quest's proclivity to market vaporware which never manifested as tangible, available products. But now that they are a part of AeroTech, perhaps this will change; I've always liked their products, and I'd like to see their product lines grow. In addition: One relatively easy thing they could do would be to re-issue the 15 mm diameter MPC/AVI Miniroc kits (they use the T15 tubing in some of their current kits, as faux strap-on boosters), which could use Estes 13 mm mini motors. (Before AeroTech bought them, Quest started that "new tradition" with their higher-powered kits, for which they recommended other companies' large motors that they themselves didn't make.) That slight diameter difference between T15 and BT-5 enabled the 15 mm (0.591") rockets to comfortably accommodate a 10" parachute (or a streamer, of course [especially for two-stage models]). The Minirocs also used a BT-5 size "sleeve tube" motor mount tube, which not only strengthened the fin assembly area (preventing body tube buckling when inserting/removing the friction-fit motors), but also enabled the motors to be retained using just an external wrap of masking tape (by leaving 3/16" - 1/4" of the sleeve tube protruding from the body tube, so that the tape could be wrapped around the protruding sleeve tube and the rear end of the motor).

In the NARCON video of the manufacturer's forum Gary stated directly with price increases coming from China it is likely the BP motors next ordered will be the last and the Q2G2 igniters can only be ordered at the same time as motors. So hoard Q2G2 when the next batch arrives.
If Estes were to do a NA0323 (UN0432) motor pack with real old style solar igniters and include abundant spares in every package, it might be a North America only product but we are the biggest market anyway. Maybe a customised bulk pack would be the easiest for them. Besides no non-USA country tries to regulate igniters abnormally. It was the elimination of 55.141 (a) (7) that started this ball rolling but it still exempts specific UN numbers. NARCON folks reported a 50% ignition failure rate for "starters". Quote:
A traditional electric match has a tiny amount of high explosive covered by a propellant (inhibitor). All model rocket and high power rocket igniters have no high explosive at all. Only propellant as the pyrogen. Some have a bridge wire and some use a semi-conductor in the dip to eliminate the need for micro-welding or winding. Time to grow balls. Jerry Quote:
