All I am assuming is that their resistance characteristics are similar. I know that they break when fired(I have tested that), and I know the resistance is generally significantly lower, but if anythi...

I have never seen one in a rocket that failed this way. I tried 3 estes igniters in series, however, and 2 lit, one did not. I then tested the one to make sure it was good - it worked instantly. Nev...

Yes, and therin lies the problem. As you pointed out, the one will heat 1/2 as fast as the other two. The other two will light first, and break the circuit, and the one will never light. Also, if the ...

Well, looks like that may have to wait... Just got off the phone with Joe - no loads until the week after mayhem, unless a miracle happens.

For that rocket, you should be fine. My dad uses the full charge (and no more) with his PML endeavour, and it works fine (4" with no piston, loose fit).

Great 😀 You may want to kiss it goodbye though - it sims to almost 100 gees 😀 Almost 500mph by 200 feet up 😆 I can't WAIT to see that

The problem is that when they are not all identical in series, they will not all heat evenly (the one with the most resistance will heat first). Then, when it goes, the circuit is open and none of the...

Absolutely - come on down and have a blast 🙂

I can't see why it wouldn't - at least with all the loki hardware I've seen (38, 54, and 75), the rings are the same size for all the cases in that diameter. I would assume AMW is the same way.

1200f, or several thousand below exhaust temps.

Parallel is ALWAYS the way to go, other than with some e-matches, and here's why: First, in series, you are dropping the voltage that each igniter sees. If you have a 12V launch system, with 3 igniter...

I talked to Joe (@ hobbytown) the other day - he's expecting 10 H999's sometime during the week. I can call him back later in the week to see if he has any more news, but as of right now, it looks goo...

Typically, at a normal launch, there are perhaps 100 flights by 20-40 fliers. There are also some spectators and family. At last Oktoberfest, there was around 320 launches, and at lats MHM, there was ...

I can't remember what I was looking for (other than some of the 18mm D's), but email sent. Also, agreed that fuddruckers are nice - I was going to reccomend quickburst, but either will work great for ...

I know, but I would rather not qualify by loosing it while trying than by loosing it on a test flight. I agree about the DD issue - still debating about whether to go dual or not.
