I won't say anything of the safety factor there, but I will say this was all wrong, as you were way over-budget for what NASA gets...

pretty cool. I think you need a longer launch rod.

I think you need a D motor. And a clear field so you can video the carnage in all its glory. Did you get the plane back?

Back in the mid 1980's one of the local club members bought a commerically available rocket launched sailplane. We launched it in a clear area with no buildings within 1/2 mile or so.

Didn't take long to find out that just touching the elevator during the power part of the launch made the sailplane into a lawn dart.

Finally after several tries, and quite a few bucks into the rocket motors, the pilot got a good flight. For about one minute. That sailplane had the glide ratio of a rock.

NOT SWEET! This is so wrong on so many levels. Jeeeez folks there is a place to stop. Look again at where this was done. I'm old, I have little latitude for this kind of wrong doing. Step up and say it is wrong ... close this thread. read your AMA rules, think what is wrong, be a grown up ... whatever is right. COME ON!

ditto!!!! very wrong!

you might want to get a life that's a little less boring...lol...,less dangerouse for nearby buildings and people on the crashing end of that bird.

Ok, yes, the location was not the best choice on many levels.

Let's stipulate this, and move on.

Do not let this be another one of those threads that degenerates so far past the point where anyone even remembers what they were upset about.

In that situation with a not so powerful rocket motor burning for a too-short duration on a high drag plane the potential for harm to persons or property was very low, probably less than for using the plane with a brushless motor.

I wouldn't have launched there because the chance of getting a good video was zero. The chance of airframe loss was greater too. It was pretty guaranteed he would lose sight of the plane and not be able to control the flight. But he knew that. I'm not willing to crucify him for not launching elsewhere. I would successfully argue that this was not a model rocket as defined in the NAR rules, and so its radically different performance characteristics makes the rules non-applicable in this situation. After all the size field is a function of altitude gained. His altitude was much less than typically attained by a half A model rocket.

It was fun to watch. It would have been more fun in an open field where we could have watched the glide after the boost.

NOT a smart choice in my opinion. That kind of stuff just gives the hobby a bad name.

Hi
His wasnt an rc model so it doesnt apply to The hobby of rc but the hobby of rocketry
Granted the site wasnt the best choice but this imho shouldnt impact are hobby but the rocketry one
Take care

OH, it was free flight? Wonder what the free flight guys have to say about it then? They have done Jetex planes for many years. I'll bet they would give this one the thumbs down, not from safety considerations, but from the slim possibility of ground level landing and risk to the airplane.

Just seems to me that it's more fun when you can see the flight and won't lose the plane. But that's no reason to attack someone. Every one of us has been so hot to go flying that we've made some poor choices sometime. And if we were willing to tell there would be some really funny stories.

I think the most damage would of been.....nothing.

There is no mass, there was hardly any inertia.

A Frisbee would of been more lethal.

Although if you go to a D size, go to a field big enough that we can see the whole flight, landing and everything. You might want to trim it for lazy circles in the air.
