Have you guys looked at this guys rocketry resume?

Whose?Also John, Warren, and Adrian, tell us more about this project and “the motor”!! Pretty please?-Ken

Awesome Talon, Tim! What was the motor? I hope it was in line with your “go big or go home” feelings which got me hooked on HPR in the first place.Congratulations!-Ken

Has anyone posed the question to Dr. J. at CTI? It would be great if he would offer up an aluminum reusable threaded front closure for at least the 54mm motors, considering the demand. As the price of altimeters goes…   Read more»

I think we need a fleet, so ALL politicians (all parties included) can go. Lawyers too. (and let’s not forget the telephone sanitizers, Nod to D. Adams)-Ken

That is cool!So what now people who said the moon landing was fake, huh? Yeah, thats right!Unfortunately, the conspiracy theorists have no interest in truth, and have already publicly denounced the photos as faked. I wish those losers would just…   Read more»

Ray,FYI, The unidentified white rocket (at the bottom of the MHM pix) is my LOC Ultimate on 6x F62 + 1x G104. If you zoom in enough, you can see that they didn’t all light. Still a good flight.Thanks,-Ken

Wow, loading the second took some serious determination! 😯

Looks like his new homemade guidance system worked as designed.

I’ve got 3 and could part with one. Again, what price range were you looking at?Alternatively, I could loan you one with the standard “return it or replace it” deal that everyone uses for motor casings.-Ken (in Longmont)

If you like the Edmonds Ecee Thunder rocket glider (aka Flying Lumberyard), I have vector drawings from the laser cutter. I was originally thinking of upscaling to 29 or 38mm and making it with honeycomb sheet instead of balsa.Mine always…   Read more»

With a J350, it’d have to be a swingwing or similar folding setup. Full width wings will be confetti regardless of carbon! Let’s kick it up a notch with a J570! This would be a nice twist from all the…   Read more»

Once someone gathers all the parcel data, it might be handy to compile it into GPS coordinates, so those walking around will know when they’re near a boundary. I’m assuming most have fences, but I’d bet not all do.-Ken

Dang. I was looking forward to it.Can you elaborate on why it isn’t happening?-Ken

I don’t think so. I pretty much have that album memorized!-Ken 8)

Interesting how the casing split grew from 71″ to 254″ BEFORE the motor failed. Sound pretty robust to me.Odd that the propellant fragments released caused explosions. Seems that once they were out of the casing (no longer any chamber pressure),…   Read more»

Engineer here, too. But there is Wikipedia!!!Sine qua non (pronounced as Americanized /ˌsaɪnɨ kweɪ ˈnɒn/ or more Latinate /ˌsɪneɪ kwɑː ˈnoʊn/)[1] or conditio sine qua non (plural: sine quibus non) refers to an indispensable and essential action, condition, or ingredient….   Read more»

Chris,I think what Shredder is getting at, is assuming that all water in the tank has been heated to the gas phase, no liquid in the tank.Shredder,I believe what Chris is getting at is, with the tank upright and the…   Read more»

Careful Adrian! We don’t want to lose you to the sailplane crowd!

Is the dc40 much smaller or more easily integrated into a rocket? I haven’t seen one yet. You’d probably be able to get dc30’s much cheaper, and for larger rockets, the dc20 is in the $75-90 range on ebay.-Ken

I’ve heard of some using a short coupler section with a piece of rod or carbon arrowshaft epoxied cross-wise in it. This makes an anchor point that ejection charges can blow past. The drilled bulkhead plate works fine, too, and…   Read more»
