Can a model rocket kill?

Can a model rocket kill? I mean, like one of the e - g sizes? I guess the plastic casing might have something to do with with it, but lets take that out of the question.

Also i'm not planning to kill anyone with a model rocket lmao.









or am i?.........

I wouldn't have thought a model heli could kill someone, but one recently did. Just assume it can, and treat it with respect, and you shouldn't have any trouble.

Given that you have no control once you ignite the motor, treat it like a loaded gun.

Never point at a person, keep the launch angle high, make sure the fins are in good shape.

They can most definately kill someone not much to discuss. It doesnt have to be one of the engines larger than a D either.

The only reason I made a recovery system for my largest rocket was to keep it from killing or injuring someone on its way back down.fully fulled it will weigh 3 pounds.

Thats because its a no brainer. If you can't see that then please avoid model rocketry.

qwerty_2008: I'll give you another possible reason which may not apply to where you live but where I do, its illegal [federal law] to launch a rocket without an operational recovery system. That rocket would be classed as high power by reason of weight and it would be illegal to launch save by a certified member of one of the national rocketry organizations. Please check out NAR or TRA and find a club near you. Or are you talking about water rockets?

No one has been killed by model rocketry in North America since the hobby started. AFAIK. Lets keep it that way.

It is a KnO3 (sugar) fueled rocket which is not the best fuel but it is the cheapest and easiest to work with when it comes to homemade fuel. One of the reasons it is so heavy is because it needs more fuel to launch because the KnO3 fuel is less powerful then modern composite fuels.

Your reasoning is false. 'Rocket candy' as its known is perfectly usable in small rockets. It seems there are fundamentals missing here so please do more research, find those in your area willing to mentor. This forum is not adequate for that.

I have made a number of smaller rcandy rockets in the past the reason I made the big one was because I had some 3" cardboard tubes laying around. Instead of waiting around for a launch that will probably never happen I should just scrap the big rocket and go back to making small ones. Rocketry is not my main hobby (if it can even be called one of my hobby's more like an interest) far from it actually I mostly build model ships and RC sailboats.
I have hijacked this tread long enough.

I've only been to one large rocketry event (in Kansas) and I witnessed a 6 foot scale V2 rocket pile-drive itself into the ground when the recovery system failed. It was at the bottom of a hole in the ground that was at least 2 feet deep. Apparently there was nothing left to salvage but, ironically, the parachute.

There was no question in my mind that if it had come down on someone they would have been killed instantly.

I should mention too it came down not 50 yards from the spectators.

That's the typical irony of a large, HPR lawn dart. The one thing that could have saved the rocket is usually the only thing to survive the impact.

A few years ago, Estes had a recall on an RTF SR-71 rocket. Not very big, even by Estes' standards... but apparently one had lawn darted, and on its way down, one of the wings grazed someone's arm requiring stitches. A thin fin or wing moving at speed, is essentially a knife. Doesn't matter if it's Balsa, cardboard, plastic or steel. It can cut. And if it can cut... it has the potential to be lethal.

Fly safe!

Witness 38mm that came in ballistic

This was an experimental flight using propellant of AP and Epoxy mix. The problem was it failed to deploy the chute and it came in ballistic. We were all lucky that day because of the early warning and nobody was within 25 feet of impact. What stopped it from being a lawn dart was a roof of a parked Volvo at the launch site. By the way a very clean hole and a costly repair ....Yes it can kill.
