I would like to propose a contest and start some discussion.
I have been reading about the Mach 9 motors that Aerotech is putting out. I was thinking how difficult it will be to make a rocket that can survive such a fast burning motor. Then on a phone call with John Wilke it dawned on me the perfect contest to exploit the challenge.
An Egg loft contest using the H999! (The motor generates a total impulse of 320 N-sec (100% H), with a burn time of 0.33 sec and a peak thrust of over 250 pounds) It would be a great challenge to get a egg to survive a 250lb peak thrust…. what do you think?

I like the idea – although I don’t know if we’d be ready for such a contest at MHM. People haven’t had time to build birds for this purpose and I would guess some serious ingenuity will be needed to find a way to package an egg to handle that level of thrust (think 35g’s or more for a traditional egglofter scaled up to accomdate the motor).
I think this one deserves to be kicked around to refine the rules to create a good, competitive set of rules. One thing I will recommend, that the egg goes inside a zip-lock bag before it goes into the payload bay. I’ll bet everyone ends up with crushed egg the first few flights.

I like the idea too but for Oktoberfest. What about launching a dozen eggs launched before 9:00? I figured losser has to fix breakfest.

Warren I was thinking of a contest for maybe 2007. Anyway now I am thinking of a pumpkin boost! better than eggs!

Well I don’t think there’d be much issue with lofting a real pumpkin on that motor – as long as we stay away from some of the giant varieties…

Heres a twist, a squash/zucchini etc of ones choosing, and inside it 4 aa eggs. Break one you lose, you a long skinny kind of guy, short but stout, in between, or neither…

a more serious proposal–dual eggloft using an AT h1000/ CTI H600 at Octoberfest on saturday, one flight. 20 bucks, and yes zip locked so we can eat them sunday. Worst flight cooks. In the case of a tie, we want hashbrowns, so KP duty as well, Three or more breaks, we want bell peppers and onions as in denver omelette. 😛

Are you talking about for altitude or duration? Also, why limited it to those motors? I propose H Dual eggloft altitude by altimeter. Eggs must be returned unbroken but any combination of certified motors up to 320N-sec.
I’m interested as long as the contest is defined early so I can prepare.

The reason for these motors is because it would be more challenging to make an egg survive an H999, H667, or some other REALLY fast motor than something like an H73J. Also, warp 9 is cool 😀
Warren B. Musselman
Well, personally, I don’t know that you could fly an egg on either of those motors without scrambling the contest even if you could keep the shell intact. As contest director, I’m VERY open to this sort of contest – I like to see a bit of a personal challenge… BUT, could anyone keep from breaking the shell on that kind of sudden thrust?
