Yeah, I was trying to figure out the photo as well. The main airframe looks completely intact (at the moment), but then I saw the motor ABOVE it! 😕 You built that thing like a tank, so if it’s totalled,…   Read more»

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

I don’t think I’d recommend trying a Warp in anything but fiberglass.

I’ve flown Warp9 in unreinforced LOC paper tube, granted not a high performance min diameter design, but no ill effects, just a stupid grin that wouldn’t go away. :DKen

Apogee is just a reseller. You can get all the info from Always Ready Rocketry, who makes it. The early version 1.0 had issues warping in high heat/high humidity, but they claim it’s cured in 2.0. Not really an issue…   Read more»

Maybe since you’re just a noob to them, you can get basic “pad manager” duties? :PKen

One important difference: They lost their field, we didn’t. Stay vigilant, save the sparkies for barren land like Pueblo!Ken

Yeah, I got my set of 38 casings from Scott just before the whole mess came down. He put a few fingers through the table saw, with a long and not-so-perfect recovery. After that he got into a messy divorce…   Read more»

Here’s a thought: what if we picked a date and a venue, and attempted to see just how many of these 70+ H125’s we could get off the ground simultaneously? I’m thinking not so much a contest with an entry…   Read more»

Wow, that sounds like fun. How many are there?I’m assuming you’re asking about the H125-20W. >70I almost hate to ask this, but can anyone explain concisely the rules regarding expired cert motors?Can they be flown on commercial launch days, or…   Read more»

Strangely enough, I read through that on the first pass. Then again, I have two 7yr. old girls who write phonetically sometimes. I saved some of my son’s early writings back when we had to study it to figure out…   Read more»

Normally, it’d be the delay element & ejection charge holder. In some of the 54 loads, it’s plugged & tapped. I think it’s all the long-burn versions. Is somewhat reusable.-Ken

Like others, I thicken it enough to do them all at once. I use tape on the edges, and a short chunk of pvc pipe (1/2 or 3/4″) dipped in alcohol to run along them to spread and smooth. Just…   Read more»

I’ve got a bunch of F62T’s lying around for the 29/60 case (and 2 29/60 cases I’d like to sell).Unfortunately I won’t be able to make this launch. Let me know if you’re interested, and you can run down to…   Read more»

Wow, 2-time grand prize winner!You have an OBLIGATION to enter again. What movie theme this time?

Cerberus is a GREAT name and certainly with the “dog” theme. Ken, you are probably right about it being a niche. Another issue is that I’ve never built a cluster (or staged) HPR rocket and I’d have to do that…   Read more»

Just a rocket name… Cerberus, with three of something, cluster?

Like maybe a 38mm version of the LOC Viper? I’d stuff that with 3 Pro38’s in a heartbeat!Might be too “niche market”, though.-Ken

Even with the high ignition reliability of CTI, I’d highly recommend moving the outboards adjacent to the central motor to eliminate any effects of off-axis thrust.Looks cool. Kind of like you peeled the 4″ outer skin off my 4×38 bird!Looking…   Read more»

My cert has lapsed, but I’ll help out as needed (or possible).Ken

Gotta be commercial. After L2, you can do EX, but not for certs.-Ken

Don’t forget, there’s also TRA (Tripoli Rocketry Assn.) as another national organization.TRA vs. NAR is a choice you can make, based upon where you’d like to go in rocketry. NAR is excellent for competition, low and mid power, and supports…   Read more»
