By the way, this morning I'm working on a little 29mm av-bay design. It fits a beeline tracker (with USB battery charger), a Raven and a shared little battery all next to each other inside a 29mm blu...

I agree, nothing but the motor should change between flights. Using either honor system or measured weight would be fine by me. I always take my little scale with me to launches, and other people p...

The BigRedBee Beeline and Adept trackers will both fit into 24mm tubes. It may also be possible to put a Raven altimeter and a beeline side-by-side in a 24mm tube, but I'd have to check on that. I h...

This contest (D, E and F altitude on one rocket) presents an interesting choice on the rocket diameter. 24mm would appear to be the natural choice, but the available 24mm Fs aren't full-impulse. It w...

Now scheduled for September 24, 25, and 26, 2010. Who's going? Other Black Rock alternatives include Mudrock, probably in mid-June, Aeronaut, probably in late July/early Aug, and XPRS, in September be...

Probably too late for suggestions, but one can dream... Never too late. Are you serious about the motor spacers though? For what reason? Jeroen Based on a few guesses. I'm guessing that there will be ...

My 24mm wish list: I'm reading this. Just so you know 😉 Jeroen I was hoping you would be. Probably too late for suggestions, but one can dream...

That may spell the end of AT single use motors, and after I've witnessed two E30 CATOS, one of which destroyed my Big Bertha upscale, I won't miss them. You can still find AT reloadable 24-40 motors f...

The 70G version has a lateral accel axis also. I recommend the 70G version because the axial accel has better resolution and can be calibrated more accurately. The lateral G information is sometimes...

Some of us beer been known to drive a day and a half each way for a waiver like that.

Well, I haven't given up on our current sites quite yet. Nor have I. The hours that I have spent camping there and looking for rockets have made me appreciate that land in ways that I never expected....

I could probably take care of the 50k waiver needs, but we would have to call ourselves the SE Colorado Rocketry club. My accountant has a several K acre family ranch in SE CO. I'm not so interested...

Wow, look how long and skinny the wings are, and that they aren't drooping. But is it just me, or do the engines look really close to the ground? The plane has a brand-new avionics system (which is s...

I second that. You especially want the part of the fin near the leading edge to be stiff so that when the wind is pushing it sideways, the back edge deflects more than the front edge to keep it from...

Wow, $100k; that's a big deal. Good for them.
