Estes Monarch Build, #7214, Finished

Blog
The Optima is a great design, at any size. I'll worry about printing a name decal next time I make decals. That Rusto Metallic Black Night paint is a favorite. I didn't worry about the break line between the two body tubes. Normally I'd fill it. I didn't notice it until now - The Monarch face card art has the same trim style as the Optima! Different colors but the same idea - vertical shiny fin ... [More]

Estes Monarch Build, #7214, Part 14, Placing The Upper Tube Trim

Blog
The upper body was spray painted gloss black, followed by two coats of my favorite Rusto Metallic Black. The black extends down 8.5" from the nose cone tip. The metallic black compliments the reflective specks in the purple vinyl trim. A 1/4" wrap of chrome is space about 1/8" from the bottom of the black. The 1/2" wide purple butts up against the chrome. Another 1/4" wrap of chrome sets against ... [More]

Estes Monarch Build, #7214, Part 13, Placing The Purple Fin Trim

Blog
The wider purple trim is cut much the same way as the chrome strip. A light wipe of glue stick and press the template onto the trim material. Cut out the purple trim, a little long for overhang of the trailing edge. The purple is rolled over the leading edge and evenly spaced from the chrome strip. The picture was taken after the overhang was trimmed off. The left side shows the ... [More]

Estes Monarch Build, #7214, Part 12, Placing The Chrome Fin Trim

Blog
With the right side of my ruler set into the root edge - The right side of the chrome strip is about 2 1/16". (The ruler has a little extra border on the left side.) This measurement is consistent from the top to the bottom. Notice the masking tape set down as a right side vertical guide for the chrome strip. Set the center of the chrome V strip on the rounded leading edge. The tails on ... [More]

Estes Monarch Build, #7214, Part 11, Cutting The Chrome Fin Trim - TIP

Blog
TIP: The larger Estes Optima kit supplies you with holographic tape trim. It's a long strip that won't wrap over the rounded leading edge of the fin, leaving a gap. Here's how I made a continuous "roll-over" piece. A fin tracing and indications of the purple and chrome trim. The tracing is mirrored so the pieces could smoothly cover and connect on the leading edge. A little ... [More]

Estes Monarch Build, #7214, Part 10, Planning Ahead For Paint & Trim

Blog
The instructions don't mention where the black paint starts on the upper end of the body. I assume the black paint separation mask is at the low end of the payload tube. The payload tube (catalog #031380) length doesn't come up on the Estes website. To estimate the length - On my computer screen, I enlarged the instruction picture close to the diameter of the downscale BT-55. The black ... [More]

Estes Monarch Build, #7214, Part 9, Gluing On The Fins

Blog
Here's the build with the rear and forward fins in place. On this downscale, the smaller fins are 4 5/16" from the rear of the tube. The rear lug is glued 1/4" from the end of the body tube. The forward launch lug is glued 7 5/8" from the rear. TIP: You can fill bubbles that form in dried lug fillets. It takes three applications of wood glue. Apply and smooth the first fillet, let dry . ... [More]

Launch! R.O.A.R., Christmas, FL, December 20, 2025

Blog
Low 70s in December? That's warm for central Florida this time of year. Winds around 5 mph. Not a big group today, some first timers who bought C6-5s for their Estes Crossfire builds. I gave them some B6-4s for the first launch. First up for me was the 2/3rds size Centuri UFO with a C5-3. Perfect boost to about 150 feet. Just as advertised, at apogee it turned over and "floated" down landing on ... [More]

Estes Monarch Build, #7214, Part 8, Downsizing The Optima To A BT-55

Blog
Downsizing is often a compromise. I don't have a Optima shaped nose cone. For now, I'll be using the nose cone from the Monarch kit. The Estes online specs say the Pro Series II Optima has a 2.5" (outside diameter) body tube. This might be a BT-80 tube with the diameter rounded down to 2.5". The BT-80 diameter is actually 2.6". This downscale is built around a BT-55 at 1.325" diameter, very close ... [More]

Build Entry
The A Frames and Fins were pressed together. The C Frames are pressed into the A Frames and Fins. Be careful handling the Fin paint while assembling.
