Manufacturers could side-step the entire NAR safety certification process just by selling the motors as fireworks. Would solve a lot of BS nonsense.

A few posts back, Crown motors were mentioned as the first composites.
They probably got through the mail by everyone KEEPING THEIR TRAPS SHUT instead of playing "shipment cop".

Yes, there is such a thing as NORMAL, if you have to ask what is "NORMAL" , you probably aren't !
Failure may not be an OPTION, but it is ALWAYS a POSSIBILITY.
ALL systems are GO for MAYHEM, CHAOS, TURMOIL, FIASCOS, and HAVOC !

PLUS, they could be lit with a FUSE !

Fuse works very well for igniting most BP single use motors that are not in clusters.
With clusters, electric ignition is required due to the need of igniting all motors simultaneously.
Green Visco fuse works for almost all motors except mini (13mm) motors due to the small nozzles. Those can use the small grey/green firecracker pack fuse.
As far as I know fuse ignition is only against the safety code if one ignites it by a non-electric means. One could ignite the fuse with a standard rocket igniter.
It being against the NAR safety "code" is mamby-pamby nonsense.

You realize that fireworks are more strictly enforced via NFPA and local ordinances than even rocketry is?

In the Internet Age anybody, anomously can drop a dime on you.

Look GH I agree with you up to a point that we are over-regulated.

Our nanny government thinks that 1 life matters. I don't. I think we ought to allow people to blow themselves up, hopefully not taking anybody else with them.

Unfortunately although we are free to do most what we want(at least for nww), people should not be allowed to do stuff that harms other people. Your rights end where my nose begins.

Jack Parsons who invented composite propellant dropped a vial of mercury fulminate in his house and did just that.

Regulation of consumer fireworks in non-urban areas of Michigan is VERY light.
In Commiefornia it is probably awful.

unfortunately for America, Commiefornia is sweeping America. It's just a matter of time now.

Here in KY fireworks are generally banned except for July 4th , Xmas and New Years Day. Cities both urban and rural, and we are mostly a rural state, can determine the actual hours on those 3 days by ordnance, and basically it's till about 10/11 PM.

Try a short length of Visco, leading to "Black Match", enclosed in paper tubes, making it "Quick Match" with a pyro-dipped head . . . Very fast, inside the tube !

you could always electrically ignite a piece of fuse...... or move to Germany where they allow fuse to ignite model rockets but you need an explosives license if the motor has more than 20g of propellant. Be careful what you wish for......you are now entering the Twilight Zone.......

Nah...thermalite. If we are going to open up the regulations, we're bringing back thermalite!
