Another project started long ago I finally brought to completion. http://www.spacemodeling.org/jimz/kc-7.htm I like the old sci-fi style rockets, so I constructed an upscaled Centuri Quasar (KC-7) based on a BT-80 body and a 24mm engine mount. The ram jet intake and nozzels turned out to be pretty easy to make Continue Reading
I previously printed an Enerjet 1340 fin can in red graciously created by Jack Hydrazine. I decided what to do with it, clone a Centur Argus. But I still needed the plastic reducers if I didn’t want to use balsa. Last night I created 3D models for the plastic reducers Continue Reading
I created 3D models for printing of the Centuri PSR-78 and PSR-813 plastic reducers. The red PSR-78 is the Centuri original, the white is my first test print using PETG filament. Centuri’s weighs 4 grams, and so does mine. https://www.thingiverse.com/thing:3912950 My first test print of the PSR-813 using PETG filament. Continue Reading
Transition and adapter leading up to the capsule. I used a BNC-60AK from Semroc, same cone as the Estes K-41 Mercury Redstone. I sanded the Redstone adapter ring off to make it match up to the Atlas. The paper capsule wrap in the picture is just a mock-up. I used 1/12 dowels Continue Reading
I used the same method for the fairing shrouds that I used on my BT-80 Saturn V using body tube. Semroc’s BT-58 turned out to have the perfect radius. And I started adding some of the corrugated details using corrugated plastic sheet material.
For a second time, I’m reviving a project I started some time ago. I’ve wanted a Mercury Atlas, so I decided to scratch build one around a BT-80. It seems like the perfect size and I’ve configured the motor mount for a 24mm D engine. I started by cutting the two specialized Continue Reading
I have too many rockets that I’ve built and just never painted. So I’m trying to rectify that.
I still have a little more to do. This is about a 1.6X upscale of the Estes Colonial Viper. Main tubes are BT-60. I offset the 24mm motor mount, I remember the the original I had as a kid tended to arch over and my research supports that memory, so Continue Reading
This was a really quick build, the Estes Fin Alignment Guide helped make quick work of the 12 fins. I bought this as an open kit, it was missing the fin sheets, but Semroc to the rescue! The long ST-8 was a little roughed up on one end, but the Continue Reading
Launched it this past Sunday afternoon on a 29mm Econojet F42-4T. Perfect flight and recovery! 4 second delay was just right. Used two 24 inch chutes.
