Thank you for this information! I don't know how soon I will get to it. But I will try to soon. c0c0m0ke

I am Exploring 3D printing., and there is a lot to know, and I know very little. I don't know where to begin. Back in November & December, I met a flyer who constructed a non-cylindrical rocket, with 5 fins. Imagine 5 long isosceles triangles bound together on the top half and 5 shorter...

When I was in high school, over 50 years ago. one of my classmates was one of 12 kids in his family. He was the third oldest, and a brilliant mathematician. His oldest brother, Paul, was equally bright. So, Steve, my classmate, told his brothers about my 8th grade rocket science project. At the...

I have no idea where to start. Here is the back story. Since last March, I have been playing with tetrahedrons, and trying to fashion some sort of stable "fly-able" version thereof. I think I have fashioned a successful corrugated cardboard model. It employs 3 isosceles triangles on top, and 3...

I believe he started with a dodecahedron, but he eliminated the bottom side and the top side. Actually, the bottom side is where the nozzle resides. By eliminating the top pentagon, the other 5 elongated pentagons come together forming a point. He said he didn't know what to call the resulting...

I have built several and given them names I have not seen any where else. A rocket that used a paint roller cover and flew on an F motor. "Fast and and Furriest." A Hi-Flyer like rocket I called "Performance Anxiety" - it separated just above the fin can, and was a rear motor eject parachute...

Nine days ago I launched my TTV using an E31-6/B6-4. I'm learning. I have tried as boosters D12 & E22 and they just don;t have enough "Umph!" The E31 has plenty of Umph, but it is a tad too long. My first two attempts probably got no higher than 200' up when the timer pushed out the parachute...

Spent shell casings work great! Knock out the primer with a nail and hammer, and replace that with a e-match wrapped in a bit of kleenix, add a drop of white glue and hang out to dry, to seal up that gap. Drying time depends on how much glue you use, ambient temp and humidity. 24 hours is...

Several years ago, the cover of "Sport Rocketry" (March-April 2017) had a picture of a three tubed rocket cluster and the tubes twisted around the center. They spiraled up to three nose cones. Now that I looked at the photo, three 18mm tubes spiral up around what looks to be a 38mm tube, and...

Curious - with nose cones off, and flying thus configured, does this whistle? Three different tones (depending how deep the p-chutes) are packed in? Does anyone build rockets for whistling capabilities? I often hear them whistle, but I think it is an inadvertent accident that they do that. I...

Let me see if they will upload. Apogee Nike Hercules - transition by cmccauley. I want you to see my inside the transition and placement of “gap vents.”

I bought the plans and followed them up to the transition between booster and sustainer. I could not get the card stock connection to work for me. I took matters into my own hands - collect as many photos I could that really showed what that looked like. With a block of balsa I carved something...

Apogee has been selling the "strap-on-boosters" (SRBs) for a while. I bought a pair when they first went on sale. They were 18mm motor mounts in a 24mm airframe. After I saw how theyworked, I requested the "hook and box" parts alone, because I thought the kit was overpriced and i could clone...

I uploaded pictures of 3 rockets I have built or started to Build but have encountered problems. My recovery system needs tuning up. Six color rocket, 29mm motor mount ruptures at ejection. How do I reinforce tube to withstand inner pressure from blowing out the sides. I have thought inserting...

I have plans for a rocket called "Double Trouble." It is a two stage rocket. The sustainer (18mm minimum dia.) sits inside the booster (38mm dia. with an 18mm core motor mount). The sustainer uses 6 fins that slide into the top slots of the booster. The booster has a thrust ring at the aft end...

To: Anonymous (Rocketry enthusiast) One of the early "Rocketry Show" podcasts, CG and Geem interviewed a fellow who launched a full scale port-a-potty. He thought long fins would stabilize the PP, but his OpenRocket simulations were disagreeing with him. After more time and research, he...

I recently started Adam Kinzinger's "Renegade ,,," I am a few of chapters in. I have been seeing him in a lot of interviews lately, as the book just came out last week. I just finished Miles Taylor's book, "Blowback ..." So far, both books have predictable messaging, similar but different. They...

Here is a humorous song from the 4 Bitching Babes, I hope you like it! Click the link and it will connect.

Phone rings. Caller ID tells me ID info is unavailable, or it is a number from someone I don't know. I have tossed my telephone etiquette aside for it now goes like this: "State your name and business." If they ask for me by name, I repeat, "State your name and business," much slower and very...
