Centrifugal force and cardboard casing. In Chuck's awesome LDRS dvd there's a close up of Ed Miller's tricopter showing the burn through. Pretty discouraging considering the E9 is a ideal economical motor for copters.

Which ART are you referring to ?
Seems LunarLos goes by Bob ?
I can tell you LunarLos is not this Art ;-)
Art "the other art" Upton
Ok, I was worried when you said ART all by it's self.
I prefer the use of last names now since the stock value of my first name has gone to heck in a hand basket ;-)

Thanks Ted, makes since

Hi,
Saw a cool and what I thought was a loose motor at a launch just this last May. A fellow made a rocket out of one of those triangular shipping box tube like things you get at the US Post Office. Had three fins at the apicies of the triangular shape and a triangular nosecone. The fellow said he had 12 successful launches but was going to use the largest motor he's tried, a K. Well it launched and disintegrated into a puff of cardboard smoke in a second! All's I saw was confetti coming down. Turned out that the model consisted of a core with a body tube, motor and recovery system. What happened was the outer body wasn't strong enough to withstand the aerodynamic forces generated by the K motor and it vaporized. The inner "rocket" continued straight up and I couldn't see it due to the falling cardboard. The parachute did deploy and the "rocket recovered normally. Some folks did see it continue on up to apogee sans fins. It gave the impression of a flight failure but it did complete safely. He did get the guts of the model back along with the pricey reusable motor casing. What I saw coming down was a parachute with a plain body tube hanging from it.:)

LOL!! Have any Arts earned the title of 'Last Year's Loser' yet?
Today was the deadline. It might take few minutes to see how big a landslide it was before the results are posted!

I am intrigued and a bit dumbfounded that it had not occurred to me, nor had I even heard of one. Do you have any links to designs or photos of these rocket motor launched kites?
I don't know and would suggest, to avoid 'wasting anyone's time', you email NAR directly and ask. The HQ email is on the main NAR page and Bunny was able to respond the same day.
Oh, I knew exactly what you meant, too -- I have a Monotcopter.

Yes.
Good.
Evidence of restraint of trade.
FTR, why?
Because Trip is VP, and if somehow Bunny were not reelected, guess who would probably get stuck with the job...
Rumor has it that Trip has organized a detail of rocketeers to protect the president in the event of a prang or cato: he REALLY doesn't want the top job.
I can understand that.
Say what you will about Bundick on (misguided) policy, but as an administrator he is competent and motivated.

This should be in the FAQ.
So he was coerced to not fly rockets on a huge dry lake even though airspace is SHARED?
TRA sucks hard. ROC sucks more. They held a big-ass launch on BLM land with VENDORS with NO BLM permit!!! Proven fact.
Jerry
Clearly no.
This should be in the FAQ.
