In MasterClass #11 – Dummy Details, Joshua Orchard and Brian Schiller explore one of the most creatively fun—and often overlooked—aspects of RC scale modeling: adding dummy details that bring an aircraft to life. This episode blends humor, 3D printing insights, painting tips, masking techniques, and DU-BRO essentials builders can rely on for clean, accurate workmanship.
A Hilarious Start: DU-BRO’s “New Nitro Motor”
The episode kicks off with a giveaway announcement for active chat participants, followed by a shocking reveal: an “all-new DU-BRO nitro motor.”
After building suspense, the hosts unveil the truth—it's an April Fool’s joke. The “motor” is a 3D-printed dummy engine synchronized to an electric motor to look convincingly functional. The gag sets the tone for a session focused on having fun while building great-looking aircraft.
For mounting mock engines, air scoops, or cowl accessories, builders often rely on DU-BRO Socket Head Screws for secure, vibration-resistant installation:
Why Dummy Details Matter: Artistic Liberty Meets Practical Scale
Joshua introduces the acronym TAR—“That Ain’t Right”—used whenever scale accuracy clashes with visual appeal or practical modeling. Whether it's rivet spacing, gun barrel diameter, or instrument layout, small liberties often create a better overall impression.
His approach: “Aim for the look, not the labor.”
Joshua shares examples such as:
-
Adjusting rivet size or spacing for visibility
-
Enlarging tiny gun barrels for structural safety
-
Simplifying panel lines for paint friendliness
-
Enhancing depth without overcomplicating builds
This philosophy encourages modelers to trust their artistic eye.
3D Printing: The Secret Weapon for Realistic Details
Joshua demonstrates how SLA 3D printers have revolutionized scale modeling:
-
Hollow prints prevent warping
-
Duplicate parts are easy to make
-
Fine details (Spandau guns, Vickers guns, and pilot heads) print cleanly
-
Lightweight accessories preserve CG balance
For assembling 3D-printed details, DU-BRO E-Z Connectors simplify linkage setup for moving parts such as dummy throttle levers or cockpit controls:
Professional Masking & Spray-Painting Techniques
A viewer question leads to an in-depth breakdown of masking and painting tips:
-
Use high-quality masking tape—not craft tape
-
Avoid sticking tape to clothing (it introduces fibers)
-
Remove tape gently using mild heat
-
Vinyl tape is best for curves
-
Oversize Post-its make excellent light masks
-
Pre-cut lozenge masks simplify patterned schemes
For holding and aligning parts safely while painting, DU-BRO T-Pins are indispensable for both foam and balsa builds:
Joshua also recommends:
-
HVLP guns for large areas
-
Airbrush + compressor + water trap for fine detail
-
Wearing a respirator
-
Using liquid mask on clear parts like canopies
For cutting canopy film or intricate masks, DU-BRO Canopy Scissors create clean, curve-friendly cuts:
Vinyl Graphics, Scale Accessories & Aftermarket Sources
The hosts spotlight several detail suppliers:
-
Parkflyer Plastics – lightweight plastic parts
-
iFly Tails – scale panels & decals
-
JP Warbirds – high-quality WWII accessories
-
CAC Graphics – custom vinyl graphics, including DU-BRO-branded Minuette decals
To apply decals cleanly and avoid bubbles, Joshua suggests using a soft cloth and a consistent, light touch—much easier when parts are supported by DU-BRO’s Foam Rubber Padding inside fuselages or hatch covers:
Closing Thoughts: Creativity Over Perfection
The show ends with a second look at the April Fool’s dummy engine and reminders about the upcoming Toledo show. The hosts reaffirm that dummy details are about enhancement, not perfection. Builders should feel empowered to experiment, take artistic liberties, and enjoy the journey—because great scale modeling isn’t about strict accuracy, but the magic of bringing an aircraft to life.
