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 honey...

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...

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 ...

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

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

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...

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) r...

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...

24 motor flight packs for 19.88! Stock up now!

If you've got that much room, I'll trade one of my DC20s for the DC30 😉 😉 I'm still working the details of cleanly dismantling the DC20 down to 38mm. I know it's REALLY close. -Ken

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 o...

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 bulkhe...

Hope mom and baby are doing well (and getting sleep!) Congratulations!-Ken

I've seen a few bugs with Rocksim 8, but nothing major. Unfortunately, it's those who are pushing the envelope who need more accurate simulations, and Rocksim fails them. For the rest of us who fly ...

Ed, Sorry to hear this. I was also on the verge of selling off some stuff before I finally found this position. Good luck in your search. I hope something turns up soon. If the lurker doesn't pan o...
