An Earlier Soyuz Build Part 1 -

Blog
With the debut of the new Estes Soyuz kit - I remembered an earlier Dr. Zooch Soyuz build. There was no plastic parts, just balsa, body tubes and rolled cardstock. The cardstock "witches hats" at the top of the strap on boosters took a few tries to get right. You even had to build the interstage trusses with dowels! The model is BT-50 based and uses 18mm motors. ... [More]

Estes USS Enterprise #1275, Part 11, Pylon Brace Fit

Blog
The pylon brace fit was very loose. No amount of glue fillets will fix this. On the left: A strip of 110 lb. cardstock was slipped into the slot, folded over and glued to the face of the brace. On the right: Look close to see the white cardstock shims in place. The fit is much tighter. Another dry fit of the pylons. The braces are inside locking the pylons in position. [More]

Estes USS Enterprise #1275, Part 10, Pylon Supports & Dowels

Blog
Set the pylon in the cardstock base (the fit is too loose) and mark the tube height for a filler/primer mask. Set the notched end in the bulkhead and mark for a mask on the other side. The pylon ends were masked for a shot of filler/primer. After the filler/primer dried, sand to surface with 400 grit. Here's the outline for the pylon cut. The straight sides and bottom were cut using my aluminum ... [More]

Estes USS Enterprise #1275, Part 9, Pylon Supports & Dowels

Blog
I fitted the pylon into the pylon brace, then set it next to the body tube. The pencil line is the masking area to keep the filler/primer off the gluing areas. On the right - the notched end of the pylon is dry fitted in the bulkhead and marked, again for a mask. Here's the pylon masked for a shot of filler/primer. After the filler primer was sanded - The cut out is revised to fit ... [More]

Estes USS Enterprise #1275, Part 8, Pylon Supports & Dowels

Blog
I'll usually fill the tube seams before gluing things together. On the left - Thinned CWF filler in the seams, On the right - The filler sanded to surface. A shot of filler/primer and sanding followed. The pylon supports got some CWF and sanding. The dowel/plywood joint got a second brushing of CWF and more sanding. The propulsion unit marking guides were cut out and pre-rolled. Press a dowel ... [More]

Estes USS Enterprise #1275, Part 7, Pylon Supports & Dowels

Blog
Removed from the die-cut ply sheet - The picture shows how rough the pylon support pieces are. Set on a flat surface, one was die-cut a hair wider. The wider piece was sanded down to the height of the shorter piece. A dowel is glued to the back edge of the pylon. Cut the dowel a little longer than the pylon. Center the dowel and glue down the pylon edge. After he glue dries, ... [More]

R.O.C.K. Launch Nov. 8, 2025

Blog
This was a "make-up" launch, the field was too muddy last Saturday from all the rain. Few participants today, three regular club members and and few first timers launching their RTF Estes Pumas. The ASP D REGION TOMAHAWK had an impressive boost with the A3-4t motor. Altitude was an estimated 500'! Touch down was on the opposite side of the field under the long yellow streamer. I'm always ...

Estes USS Enterprise #1275, Part 6, Internal Support Ring

Blog
The internal support ring (RT-99D, 3.7" diameter) has to fit over the "hump" in the primary hull bottom disk. Cut the template using a straightedge on the straight lines an scissors on the curves. The template doesn't go all the way around the support ring. Mark the cutaway crescents with pencil. Cut the crescents out with a sharp knife. Here's how the cuts are placed on ... [More]

Estes USS Enterprise #1275, Part 5, Cutting Out The Vacu-form Parts

Blog
I saved the large hull disks for last. As before, trace around the edges with a ball point pen. Score along the pen lines. Free up the edges for easier bending and cracking by cutting relief segment lines. Sand the disk edges with a block. The right side picture shows the upper and lower primary hull halves dry fitted. Note the overlap of the top half. [More]
