A Raven, a beeline, and a battery can also fit side-by-side in a 24mm airframe tube, but you have to spread them out a bit more so that the total length is more like 2.7 inches. There’s also no room…   Read more»

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 blue tube coupler….   Read more»

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 probably do too, so borrowing…   Read more»

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 have bench…   Read more»

Probably too late for suggestions, but one can dream…Never too late.Are you serious about the motor spacers though? For what reason?JeroenBased on a few guesses.I’m guessing that there will be a case that’s the same length as an Estes D…   Read more»

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 for $6.50 per flight,…   Read more»

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’d love to…   Read more»

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 in a…   Read more»

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 similar in several…   Read more»

When using a vacuum bag, you’ll want to put the bag fitting on the bag some distance from the layup since you don’t want an imprint of your fitting on your layup. The fitting should be linked to the layup…   Read more»

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…   Read more»

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

As I usually fly minimum diameter, I always orient the core between fins and I like to use carbon airframes on moonburner shots, as I know carbon is a better insulator than glass.Thoughts?Actually, carbon fiber is a great heat conductor…   Read more»

Thanks for the useful info, Ed.-Adrian

There’s something called the L3 Syndrome, which is when once you’ve achieved it, you either drop out (bad thing), or find another direction (good thing). I’m looking for a new direction. JW is our altitude guru, as well as other…   Read more»

Awesome. Thanks for the link, John.

For the SSSS, the new CTI I216 is specifically designed for taking the I altitude record. It should do better than the I600, and still fits in the North site standard waiver. And it would good to support Dr. J’s…   Read more»

I was in Jax Farm & Ranch and saw those – they look very nice…add some fire retardant to the water and think they’d work great.5 gallons * 8.4 pounds/gallon = 42 pounds – we might have to start some…   Read more»
