Having a transmitter board at MHM is a good idea. (Thanks Greg) Taking it a step further, let's post what frequencies we're planning on using in this thread, so that those of us with adjustable frequ...

Jason,Thanks. I'll be Tx-ing in the 4xx range, so we won't cross signals LaughingHave you ever found out which band has better signal up there? So was that you doing the L2 on the 1st? I'm trying to p...

Ken, I have programmed a few existing Parrots to do a low-altitude main deployment (like the one I used for my cert flights), but most have been programmed with a default baro-based, mach-inhibited ap...

Ken, One of the three outputs will be a baro-based at apogee. Did you mean that you wanted two of the 3 charges to do that? If an ematch or pyro prep failure is a concern, two charges could be run o...

Warren, I'll see what I can do, while still keeping it general-purpose. 10 Hz may be do-able. The real-time data is 8 columns of ASCII, coming out at 115kbps, so faster than that would probably be t...

(cross-posted from rocketry planet) I've been putting off ordering another batch of Parrot parts, Parrot batteries, Parrot circuit boards, etc. etc, but the time has come. I'm out of Parrots that hav...

I like the eye nut concept because it puts the load straight into the threaded rod, which is the only thing typically holding the ends of the av bay together. Otherwise, the offset of the u-bolt from...

Could the club get the tower in time for MHM?

Thanks, John. I'd forgotten how fun it is to launch a rocket and get the whole thing back. 😉 Wish you could have been there. It has been classic Colorado springtime weather with record-setting mid...

Well, the charges worked again. In fact, pretty much everything went smoothly for me yesterday. My level 1 flight went out of sight, which I wasn't expecting. But I never lost radio signal, and fr...

Yes, a 9V battery will fire an Estes ignitor. That's actually how I've been doing my ground tests recently, since I seem to have misplaced my Estes launch controller. I didn't notice any delay; they...

Adrian, The chute should be 36" across, you may have a mislabled one. No worrys, I will have a 36 with me, we can swap it out. Actually, after some deployment tests this evening, the chute that I hav...

Adrian, I found 3X E12-10 Ellis loads 24mm. I will bring them this weekend Cool. Thanks for thinking of me on that. I'll be sure to bring my checkbook. Looking at the motor cert info, the Apogee E6...

I think I'll be making some more altitude attempts: F10 attempt #5Ellis 24mm G attempt #1.Maybe a 24mm E6 I'll also fly my Thunderbolt, assuming it survives this Saturday.

A small chute will open differently depending on how you pack it. If you use the method that puts the shroud lines in the chute and then fold it up and roll it up, it will open fast but if you rap you...
