Manufacturer: QuickBurst

PicI recently had t' opportunity t' evaluate igniters from QuickBurst, a company offerin' both igniter and launch control products. Ya scallywag! Avast, me proud beauty! They have an igniter product for most every rocketry application, includin' black powder motors, me bucko, arrr, electronically fired ejection charges, and both mid-power and high-power composite motors. Well, blow me down! Aye aye! I received a ‘Six Pack’ sampler, me bucko, me bucko, which included two each o' their Hot Shot electric matches, Slim Gem igniters, and Fat Boy igniters.

My Six Pack came in a sealed plastic package with their leads shunted. Ya scallywag! I also received product information sheets, a price list, and an order form. Well, blow me down! T' instructions were comprehensive, givin' detailed descriptions o' t' products, me hearties, notes on their usage, me hearties, and precautions. Well, blow me down! Avast, matey, me proud beauty! T' followin' table summarizes t' igniter specifications:

T' Hot Shot is a dipped electric match that is primarily intended t' electronically fire black powder ejection charges but can also be used for Estes black powder motors. They can be used with 9 - 12 volt systems, shiver me timbers, but users are cautioned t' make sure their 9-volt batteries really provide a ‘full’ 9 volts (i. Avast, me proud beauty! e. Well, blow me down! Duracell 9. Begad! 5 volt batteries). Begad! Aye aye! Other cautions include accidental ignition from continuity check circuits and handlin' care. Aye aye! QuickBurst wisely recommends that you test t' igniters with your ignition system before bettin' your rocket on them.

T' Slim Gems and Fat Boys are both similar devices with t' latter bein' slightly larger in diameter. Begad! Both include a bridged element embedded in a cast pyrogen. Aye aye! Avast, me proud beauty! T' elements o' both are light gray, arrr, smooth cylinders. T' burn temperature is advertised t' be a hot 3,500 degrees Fahrenheit. Blimey! Accordin' t' QuickBurst, these igniters “are capable o' ignitin' anythin' that will burn. Aye aye! Begad! ”

I used t' QuickBurst igniters in several applications. T' followin' is a summary o' t' results:

Note 1: Today I finally got a chance t' use t' second Fat Boy igniter. Blimey! Instead o' lighting, shiver me timbers, it popped, shiver me timbers, blowin' t' top 1/4 off and exposin' t' wires. Begad! However, shiver me timbers, I don't think I'll change me overall ratin' due t' this problem. Avast, me proud beauty! My thanks t' QuickBurst for t' opportunity t' try these out!

 Since I didn’t have a chance t' tests a cluster configuration, I thought that similarity in t' igniters’ resistance would provide some indication o' their suitability. Although two items is nay a significant sample, matey, I decided t' document t' measurements anyway. Aye aye! Blimey!  

A couple o' notes on t' Slim Gems: I test fit one o' these igniters in a G80 motor before t' launch. Avast, me proud beauty! T' fit be tight, but I had no problem insertin' it. However, at t' launch site, matey, I could nay insert it more than about an inch. Ya scallywag! Begad! Murphy’s Law strikes again. Therefore, me bucko, I used both o' them in H123’s. Blimey! In both cases, thar was a noticeable delay betwixt when t' first smoke be spotted and ignition. Avast! T' results, however, shiver me timbers, me hearties, were successful and this comment is provided only as a side note.

PicConclusion

First, I need t' provide me perspective on t' igniter market. Ya scallywag! Begad! I can buy reliable igniters for any motor size from local vendors. Begad! In addition, arrr, all Aerotech HPR motors now come with their FirstFire igniters, me hearties, which have proven 100% reliable for me. Avast! Finally, anyone with an IgniterMan kit can easily make inexpensive, matey, reliable igniters. Thus, me hearties, it will be difficult t' impress me.

T' four igniters I used performed well, arrr, with t' exception that t' Slim Gems did nay fit in a G80. From me standpoint, this is a big deal. Avast! Avast, matey, me proud beauty! Since they failed t' meet t' intended use for mid-powered motors, matey, I deducted a point and a half from me score. Blimey! Arrr! As for cost, they seem comparable t' t' other igniters that I have bought at launch sites. Blimey! This comparison is somewhat ‘apples and oranges’ since t' on-site igniters don’t have shippin' costs tacked on, arrr, and I only know t' cost o' t' QuickBursts before shipping. Avast, me proud beauty! Still, me hearties, I don’t think t' difference will be significant. Avast, me proud beauty! Well, blow me down! If I could get QuickBurst igniters at a buck apiece from local vendors, and t' Slim Gem was a skosh smaller, then I’d certainly buy them.

  • QuickBurst - Hot Shot Ignitors By David Montgomery

    The Hot Shot igniters are low current igniters. Used on the ground for black powder clusters or any other black powder applications. It has 12" leads that will reliably ignite clusters of black powder motors using the output of your launch control. The entire Hot Shot has been redesigned. They now have smaller lead wire and a smaller head. This means they will easily fit into the 13mm, 18mm, ...

  • QuickBurst - Twiggy Ignitors By Art Upton

    ( Contributed - by Art Upton - 08/28/04) This ignitor is designed for the small composite single use Aerotech and Ellis Mountain motors. The ignitors come in a 10 pack for $10. They are oval in cross section shape which is what is unique about them. As in the photo, they fit perfect in the AeroTech 24mm F21. They are a perfect fit in the Ellis Mountain 24mm G37 as well. The only CON I ...

  • QuickBurst - Hot Shot Ignitors By David Urbanek

    I had the opportunity to use the Quick Burst igniters recently. I have tons of praise and one complaint. I'm not sure what the after market opportunity will be for igniters at present since Aerotech now makes and supplies a reliably igniter with each motor. For experimenters, folks with NAR certified Kosdon motors, Ellis Mountain, RATT Works, etc, these are very nice igniters. Fat Boy ...

  • QuickBurst - Fat Boy, Slim Gem, and Hot Shot Ignitors By Nick Esselman

    Whether you call them igniters or ignitors...these work. I don't have a lot to add after the above reviews, however, I would like to comment on each briefly: Fat Boy igniters: You're dealing with an igniter that is 5.5mm in diameter and 25mm long. The diameter will dictate which motors it can be used in. I used one in an I161 successfully. It ignited the motor instantly. No chuffs, no ...

I second the fact that Igniterman igniters are reliable, and it is way less expensive than Quickshot. The only plus I can see is the small igniter which can be used for altimeter, but Oxral and Daveyfire provides a more sure low current ignition, and its reliable too.

I have to chime in here: these ignitors have saved the day for me with fill hose style hybrids. I've had close to 50% failure with any dipped ignitors. When you assemble an Urbanski-Colburn monocoque hybrid, you have to put the ignitor in or near the preheater grain, then slide the fuel grain over the fill stem & ignitor, then insert the whole thing into the motor tube. This is ample opportunity for dipped conductive layered ignitors to fail. The QuickBurst ignitors have an epoxy compound potted over a nichrome bridge, and have worked perfectly for me since I switched to them. I've also handed them out to others for 'stubborn' motors with a 100% success rate. Highly recommended!!!

I found these to be great igniters. I've used the Twiggys in many different motors. I once used them in a two G35 cluster with perfect in sync ignition. I also have has some extremely stubborn motors that neither Magnelites nor dipped Daverfire 28Fs could ignite, but the Quickburst igniters didn't fail.
