I recently posted a picture of the experimental fighter I was going to be working on, and once I started construction, decided to do a build thread. Mainly because one guy on Facebook wanted the file so he could build one too, and I wanted to show how I did it, and help avoid gotchas.
This is what I am building: EDIT... the rocket has 3 fins, but the initial picture only showed 2, so I got a better one that shows 3 to avoid confusion.
Rocksim file attached at the end of this post.
Okay, I assembled the body tube in 2 sections, one 14" and one 8" with a coupler in between. I previously had been using Bondo glaze putty, but found some CWF that wasn't grainy and nasty like the first tub I tried it with. I sanded it, etc, no pictures.
Motor mount, one error in the Rocksim file: I had the forward centering ring too far forward, and there wasn't a ring in the middle to help hold down the engine hook, so I used some aluminum duct tape (yes, the real thing, not the usual "duct" tape).
As for the rear transition, its the one from a package of BT-60 body tubes, the one they used on the Sprint upscale and has a slot for the engine hook.
Next up was the fins. I did them in 3 parts, using a posterboard cutout split into 3 parts, sanded and glued together. Pretty standard.
Onto the wing pods in the next post...
