Interesting question if the preinstalled igniter is a dud. In that case, would it be removable and one could supply their own? If not removable, then what? Respectfully, one is eventually going to be a dud if enough get out into circulation. (Even if the igniter performs nominally, some grains can get a coating of oxidation on them and be hard to light if the grains are old.)I wondering what's the plan if the preinstalled igniter is a dud, or is that not common in K+ motors?
Ahhhhh, The OP originally posted that he and his partners were in business making/selling motors previously. I would presume they are already well aware of the NFPA rules and requirements. I'm sure they will be going through the motor certification process and all that will take time. Remember, the motors need to be certified in order to be salable to general fliers. Research propellant (technically) can't be sold.How you get past NFPA 1127 4.13.5? Just saying, you'd need to have a change in the NFPA requirements. Good luck there!
They don't soil their shorts because they meet the best practice requirement by doing final prep at an away table, after they get approval of the RSO and before they go to the pad. They are the prescribed distance away from people both behind the LCO table and from the pads. It's .big boys and girls launches at big vents, not your average L1/L2 flyer.The head in igniter used for multi staging is a valid analogy here and doesn't seem the rule mavens soil their shorts over it as long as a best practice is used. (Like not applying power to anything until the stack is upright on the pad.)
That is not correct. It is installed at the pad or a designated area. The rocket is also to be situated to minimize risk to people. The rocket does not have to be in a vertical position.The issue is that the safety code explicitly calls for the igniter to be installed on the pad with the rocket in a vertical position.
Screw/snap in forward bulkhead/plug with the integral igniter? With the popularity of screw-on motor retainers these days this doesn't sound too bad for L2 motors. Routing the wires out of the booster to hook up with the pad leads will be an interesting build challenge, that and not taking the pad leads along for a ride.Heada. I didn't design the igniter. IF you'll give me some time, I'll explain the entire igniter to everyone. I can assure you and all those concerned that the igniter system WILL pass NAR inspection. IF however, they don't pass muster, there are always up-the-throat igniters. Right? Lol! We just think our igniter system to be very innovative.
Not only that Heada, but our prices are going to amaze you! I want you and others to be happy with our prices.
OK inexpensive!!! Nothing really "cheap" in this hobby!! As far as motors go nothing inexpensive neither, not yet anyway!!rcktnut. Sheesh! Can you use another term besides "cheap?" lol! How about inexpensive? I like that term much better! The motors will be designed as such that you could used an up the throat igniter if you so desired.
We all look forward to it. Until you can provide details (motor data, thrust curves, PRICES), please, I'm begging you, shush. Answer questions and, if you don't have an answer, just say so.TNX rknnut! And you're sure right about that! NOTHING is inexpensive about this hobby! But, I think when you see our motors and their prices, you're going to be pleasantly surprised. That is if you buy from a current motor manufacturer. I don't know where you buy your motors and I don't care. Maybe you make your own. But I can tell you this. If you're buying from a motor manufacturer, I can tell you we're going to knock the socks off their prices. THAT'S a promise!
Don: This part of the thread is much more enjoyable for both of us instead of the negativity of the safety Nazis and Armchair Engineers I got licensed in 2013 and have never learned CW, but I do have a mfj paddle that another ham friend of mine gave me to practice with, but I really only have practiced my call sign. I did fall in love at the Dayton Hamvention when I stopped by the Begali key table and tried out all of their keys as they are the Rolls-Royce of keys.Hi Hobie. Nope. Haven't read your page on qrz just yet. Glad you found me. How long did you say you've been a ham? I've been a ham since 1983 when I got my original call sign KC4KGD. Sometimes I wish I had kept it but a call sign with an N in the beginning is a sort of a rarity anyway these days. It's pretty good for working CW. Do you work much CW? I have several keys but I usually use my straight key. I don't work fast CW must. Usually 12-15 WPM is about what I do. Even slower if I'm talking to a new ham who is just getting into CW. It's sort of a dying art but I love the nostalgia.
I mean, nothing says cheerful positivity like Godwin's Law and name-calling.Those armchair Nazi's don't bother me. It comes with the territory. I chalk it up to jealousy. Most are either wanna-be motor manufacturers and don't have the money or brains to do so, or are simply naysayers. No big deal. I'm a positive person. I like positive people. Those who aren't, I typically brush off.
