Here's the latest status: Next comes fillets and tip-to-tip unidirectional carbon. After thinking about it a bit, I believe that by orienting the fibers so that from the fin root the fibers are angl...

Later I'll post more on some cool new features I have incorporated into the firmware while waiting for the board assembly to get done, but first a status update: The board assembly turned out to be a ...

IF - they are done by then, hold on to mine and I will get it from you at the launch too. If not, let me know and I will pick it up from you, that will save the shipping......Greg O.k. I'll give some ...

The fins are coming along. After some sanding they're 33 mils thick and 1.1 grams apiece. Unidirectional carbon fiber is funny stuff. The fins are now very stiff in bending in the usual way fins ben...

I definitely will, assuming I get done with them by then and I attend the launch. Still a little too much that could go wrong before then to make a firm promise, though.

Alas, it gets even sillier. CNN's headline is now "Jet dodges rocket-like object in air." I hope those passengers were belted in for those emergency rocket avoidance maneuvers. 🙄

Thanks for your order. My wife tells me that the panel of boards just arrived from the surface-mount assembler, so I have my fingers crossed, too. It will really suck if there is an assembly error or...

Here's the avbay, Beeline side up: And Parrot side up:The avbay is 2.4 inches long. The helical wire is the Beeline's antenna. The Parrot will keep it off until apogee after the deployment charge ...

Thanks, Ed. I'd like to take you up on that sometime, but probably not for a while, unless I lose this one right away. You'll probably have turned it into motors by then, but I'll contact you when th...

The extra layer of unidirectional carbon brought the thickness up to 0.03 and the mass up to 0.8 grams each. They're amazingly stiff bending them as if they were attached to the airframe, but pretty...

Here's the tube after it came out. I sanded it a bit and hit the middle part with some clear coat. It's almost 13" long, and 29 grams. It seems much stiffer and stronger than it needs to be. But I...

The av-bay I'm working on fits a Parrot, a Beeline, the Beeline antenna and two batteries (one for the alt, one for deployments + tracker) in a 24mm coupler tube, about 2.4" long. The boards and batt...

Thanks for the kind words of support. An F32 would do a bit better than an F10, but either one should be able to crush the TRA record, given an optimized rocket flying a Beeline and a Parrot.I'm confi...

I'm working on my next record attempt bird, and I'm going back to 29mm to see what I can do with an F10, the SSS, and the new Aerotech G80. I got some braided carbon sleeves, fiberglass sleeves, and ...

It's looking like a complete success so far. I couldn't be happier for those guys. A lot of them are the same folks who worked with me on the failed Mars Polar Lander in 1998, which was a very simil...
