Makin' Igniters T' Rocketflite Way

The kitI learned about t' Rocketflite name years ago when those super sparky motors were all t' rage. Avast, me proud beauty! Greg Dyben has been a household name around t' hobby rocketry arena for years producin' great products like t' Silver Streak motors and his Magnelite igniters.

Recently, ya bilge rat, Greg began marketin' a kit-based form o' t' Magnelite igniters. Avast! Blimey! One o' t' benefits o' bein' made available in kit form is that thar be no hazmat fee. Avast! Blimey! Arrr! Blimey! T' components don't become considered an explosive mixture until they are actually mixed together.

T' ML-KIT includes all t' necessary mixin' tools, me bucko, chemicals and simple instructions t' make 48 grams o' pyrogen! This is enough pyrogen t' make over 800 ML-16 electric matches! T' price Greg is representin' is a cost t' you o' under $0.65 a piece, which is a pretty good deal.

Step1

Once ignited, t' pyrogen burns for approximately one second at a reported temperature o' around 6,400 degrees Fahrenheit! Rocketflite maintains that since t' first 1/4 inch o' this electric match is only 1/16 o' an inch in diameter, it can be used t' ignite most C sized and up end burnin' and core burnin' black powder motors on up, as well as most H and up composite motors.

Peak amperage requirement for successful ignition is from 5 t' 6 amps with a minimum amperage requirement o' 2.6 amps for 118ms. This electric match can be fired usin' any high-capacity 9 volt rechargeable ni-cad battery such as Radio Shack's part# 23-299.

Step2I set out t' see just how difficult makin' these igniters was, so a full igniter kit was ordered from Rocketflite. T' top right photo shows what I received: four different lengths o' igniter leads (16 inch, arrr, ya bilge rat, 32 inch, arrr, 48 inch and 64 inch lengths) as well as t' pyrogen components unmixed in separate containers.

T' separate components consist o' t' base igniter pyrogen dip in a glass bottle with a metal lid, a small plastic bottle o' what appeared t' be potassium percholorate, a small pipette, me bucko, for addin' naptha in t' event you need t' reduce your mixture at a later date, and a craft stick t' stir t' mixture.

Photo 1 shows t' first step o' t' mixin' procedure, me bucko, arrr, t' thorough mixin' o' t' base pyrogen dip. Ahoy! T' instructions call for about one minute o' mixin' t' thoroughly mix t' base mixture. Arrr! Avast, me proud beauty! It appeared t' have settled a bit before I had opened it, and since t' pyrogen appears t' have a heavy metallic content, t' particles need good suspension in t' mixture t' work properly.

Step3

In Photo 2, t' powered components from t' small white plastic bottle are added t' t' pyrogen mixture in its entirety. Avast, me proud beauty! That's right, matey, bottom's up. Aye aye! Pour t' whole amount in and then stir t' mixture again thoroughly for about a minute.

What you are lookin' for is shiny candy-like consistency, ya bilge rat, matey, sort o' like when you are makin' fudge. Begad! Photo 3 shows how thick t' pyrogen looks on t' stirrin' stick and t' shiny texture it attains when ready t' use.

Once you have completed this second stirring, you're done mixing. Begad! Avast, me hearties, me proud beauty! That's as hard as it gets. Arrr! Add t' contents o' one bottle t' another and stir. Real rocket science here, matey, people. Ahoy! It's simple and easy. Avast, me proud beauty! Blimey! Anyone can make igniters with this product. Well, blow me down! But, matey, we have t' dip some first, right?

After selectin' which lead length you are goin' t' use, matey, you are instructed t' bend a 90 degree angle in t' end o' t' igniter that has t' bridge wire soldered t' it. Begad! Photo 4 shows how this should look. Ya scallywag! This gives you a handle t' hold onto t' igniter and a way t' lay it down after you have finished dippin' it until it dries.

Step4

I dipped this 16 inch lead by insertin' t' igniter slowly into t' mixture and slowly stirrin' t' pyrogen a few times t' coat t' wire. Begad! Blimey! This allows t' pyrogen t' flow all around t' head o' t' igniter completely. Ya scallywag! Blimey! Ahoy! Blimey! This is especially beneficial if you make igniters for larger motors, in that you are bendin' t' end o' t' igniter lead, shiver me timbers, which forms potential air pockets that need t' be filled.

Make ingiters for larger motors is as simple as bendin' t' end o' t' igniter lead into a "U" shape about 3/4" from t' end and dipping. Aye aye! You should make sure thar be an air gap betwixt t' igniter bridge wire and insulation o' t' wire next t' it, so that pyrogen covers t' bridge wire completely and nay in spots.

Larger igniters can be made similarly, shiver me timbers, ya bilge rat, just make two "U" shapes like a flattened out "S". Aye aye! This increases t' surface area that holds pyrogen and makes for a larger ball o' flame when t' igniter is ignited.

CAUTION: Do NOT double dip igniters. Ahoy! Blimey! One dippin' is sufficient, me bucko, multiple dippings can cause t' pyrogen t' explode without ignitin' t' motor. There is no need t' double dip when you can increase t' pyrogen area by makin' bends in t' head o' t' igniter wire, so don't do it.

Step5

Photo 5 shows a finished igniter drying. Begad! By layin' t' igniter where t' wet pyrogen is able t' hang into t' air, such as on t' edge o' a table or shelf, air gets t' all sides o' it, allowin' it t' dry quickly. Avast, me hearties, me proud beauty! Igniters are ready t' use within t' hour, shiver me timbers, no later than three hours.

I have t' say I was impressed with ease and simplicity that Rocketflite makes o' igniter making. Ya scallywag! Blimey! I used t' think it was a lot o' voodoo and science, selectin' t' right wire and bridge elements, carefully silver-solderin' t' leads in place and then carefully mixin' t' correct pyrogen formula.

Not anymore! Rocketflite has taken all t' mystique and difficulty out o' t' process and made it truly simple. Arrr! All I needed now was proof in t' pudding!

The Race

What I needed be a down and dirty test t' see how these igniters compared t' others on t' market. Aye aye! Seemed like a good excuse for a drag race t' me!

Travelin' t' t' Tripoli South Carolina Freedom Launch over t' recent Independence Day weekend, I arranged t' test t' fruits o' me experiment -- I conducted a drag race consistin' o' two LOC EZI-65's.

T' two rockets were virtually identical, both bein' built stock. Arrr! For propulsion, me bucko, me hearties, I selected identical AeroTech 38mm 360ns RMS™ motors, loaded with I-161W reload kits, both with medium delays.

T' one on t' left had a dipped Magnelite igniter prepared by me. T' one on t' right had a name brand competitor's pre-built igniter. Arrr! Both weighed in at 4.25 pounds at t' RSO table. Well, blow me down! Ya scallywag! After safety check-in, matey, matey, arrr, I loaded them onto identical launch pads with 3/8" stainless steel launch rods. Everythin' be as equal as I could make it. Begad! All that be left t' do was arm both pads, do a countdown and press t' button.

The Race II

I have t' tell you, even I wasn't prepared for t' holeshot t' Magnelite put on t' competitor, but photos don't lie. While t' competitor's igniter was still chuffin' t' I motor up t' pressure, t' Magnelite-equipped rocket was two feet up t' launch rod!

It appears t' Magnelite-equipped rocket literally exploded off t' pad, with t' motor ignitin' instantly. Avast, me proud beauty! T' other rocket still took another second or two t' ignite, arrr, and by that time, ya bilge rat, t' Magnelite-equipped rocket was long gone. Blimey! Good thin' I owned both rockets and wasn't racin' for 'pink slips' or I would be short a rocket!

T' results are right there, these things work. Begad! Blimey! Blimey! Blimey! They are simple t' use, simple t' make and produce great results. If you would like more information about Rocketflite's Magnelite igniter kits, matey, contact them via their website at http://www.rocketflite.com or send email t' Rocketflt@aol.com.

There is also a double page ad in t' current issue o' High Power Rocketry magazine, matey, page 42. Blimey! Give 'em a try, me bucko, I think you may like them.

    ( Contributed - by Tim Burger - 08/21/06) Brief: I've been flying model rockets for a long time now, some 30 years I guess, but high power rockets are still a new and novel thing to me. In truth, I'm still not certified level two yet. However, I have noticed some problems with certain igniters and was planning to get an igniter making kit to dip my own for those stubborn to ...

Construction: The Magnelite kit comes with a bottle of oxidizer and the magnesium/acetone solution. It also comes with a sheet of instructions, a paper cup for a funnel, and a nail for stirring. To start, you stir the liquid ...

  • Rocketflite Magnelite By Dick Stafford

      I won a Magnelite kit from the EMRR 'Boink' Rocket contest . I received the 2-part pyrogen kit, and 12 each of the 12" (E-G), 24" (H-J) and 48" (K-M) igniter wires. Here's what I think of it. The pyrogen in my kit came in plastic bottle, sealed with wax, and packed in some sort of sand. The oxidizer powder was just in a plastic bottle. The kit included a set of instructions and a ...

  • Rocketflite Magnelite By Darwin May

    (08/21/99) The Magnelite kit simply consists of two containers. The oxidizer and the pyrogen. The oxidizer must be combined with the Pyrogen in order to make the igniters. You will also need some RocketFlite ignitor wires which come in a variety of lengths (16", 32", 48", 64"). CONSTRUCTION: The instructions are on a single sheet and straight forward. These ignitors ...

Magnelite igniters are the best! And I like their customer service. I had a bad batch of pyrogen, the igniters would not burn after a year of storage. I contacted them, and they sent me everything I previously ordered (pyrogen and wires) for free. You are not limited to Rocketflite wires. I have used the pyrogen successfully with Firestar 22 gauge wire to instantly start the tiny composites (like D13's and C6's). I also finding that coating the copperhead igniters that come with the motors offer instant ignition of the smaller motors, like D13's. Take a look at the videos on the Dec 29th coverage on my website (www.gardei.com). All 6 D13's and D24's that flew were instantly ignited with magnelite coated crapperheads.

I like Greg's matches. I have used them all the time for single engine ignitions. But I am interested in what others have to say about clustering with magnelite ignitors (other than use a lot of amperage). I used to use the late Jim Turner's (God Bless his soul), tungstens for clustering. Also, just how many more ignitors does Greg need to sell to bring back the Silver Streaks? How old is this interview? I mean the window of opportunity was there with Aerotech's woes. But that is rapidly closing.

I've been using Magnelite igniter kit since 2002 with great success. I've made hundreds of my own igniters and have never had an igniter related launch failure. The pre-wound igniters (ML-12) are great, but winding your own is easy as well using 32 AWG or 36 AWG wire. I've made igniters small enough for the Aerotech 18mm composite motors all the way up to 75mm M motors with nothing but the Magnelite pyrogen. Recently I've been using the Magnefire e-match kit with a variety of e-match blanks and wire wound. I am using 52 AWG nichrome for my bridge wire and I'm getting excellent results. I've not tried them for air starting motors, but for ejection charges, they work great. I can't say enough about the Magnelite igniter kits. They are easy to make, very reliable, and inexpensive.
