In MasterClass #9, Joshua Orchard and Brian Schiller crack open boxes of onboard electronics from Horizon Hobby and Spektrum, diving into the modern tech that will power the Old School Model Works Minuette. From brushless motors to smart receivers and onboard glow systems, this episode blends classic balsa building with cutting-edge RC technology—while also spotlighting essential DU-BRO hardware that makes every installation reliable.
Community, Tools & Warm Weather Banter
The session opens with lively viewer interaction as the hosts joke about warm weather in February and revisit topics from previous classes. They chat about different razor planer options—handy tools for shaping balsa—and where to find quality versions online. The community Q&A sets the stage for a relaxed but information-packed episode.
Brushless Power: Motors, ESCs & Smart Telemetry
The first major unboxed item is the E-flite Power 25 Brushless OutRunner—a reliable, efficient choice for sport models like the Minuette. Joshua explains the difference between brushed and brushless systems, reminding viewers that brushless motors must be paired with brushless ESCs.
Enter the Spektrum Avian 60A Smart ESC, which brings high-value features like:
-
Motor RPM and current telemetry
-
Power consumption tracking
-
Data integration with Spektrum Smart receivers
This combination gives pilots detailed insight into system efficiency and flight performance.
Smart Batteries, Sensors & Telemetry Receivers
Next up is the Spektrum AR637T, a receiver packed with technology: integrated telemetry, a gyro, and a barometer for altitude readings. The hosts explain how not all receivers are telemetry-capable—making the AR637T a strong choice for modern builds.
They also discuss:
-
Smart batteries that report charge state
-
ESCs with data logging modes (such as Castle Creations)
-
Airspeed sensors that help warn pilots before stall conditions
It’s a deep dive into how far RC tech has evolved.
A giveaway follows, rewarding viewers with a DU-BRO hat and hoodie for RC trivia questions—including one about the origin of balsa wood (Ecuador).
Smart Chargers & Battery Chemistry Care
The Spektrum Smart Charger makes an appearance, showcasing features such as:
-
Automatic self-discharge to prolong battery life
-
Cycle count and internal resistance monitoring
-
Compatibility with LiFe receiver packs, which charge faster and safer than older NiMH systems
This setup forms a comprehensive ecosystem for managing electric power systems.
Onboard Glow Igniter: Mixing Old School & New Tech
Joshua then unveils a custom onboard glow igniter system incorporating:
-
A buck converter to regulate glow-plug voltage
-
A digital switch for remote activation
-
Telemetry feedback for glow-plug voltage
This helps prevent dead-stick landings—especially useful for smaller glow engines.
For organizing wiring during systems installation, Joshua highlights a must-have for clean routing:
Landing Gear Assembly Tips & DU-BRO Essentials
To close the episode, Joshua demonstrates soldering techniques for landing gear, using copper wire wraps and explaining why mechanical fastening before soldering creates far stronger joints. He even shares a fun trick: ketchup cleans oxidation off solder joints surprisingly well.
This segment ties perfectly into several DU-BRO components every builder should have:
1. DU-BRO Treaded Wheels
Durable, true-running wheels ideal for sport models like the Minuette.
RC Plane Wheels
2. DU-BRO Heavy-Duty Landing Gear Hardware
Perfect for securing gear legs with confidence.

4. DU-BRO EZ Connectors
Great for adjustable linkages on throttle or nose gear steering.
E/Z Connectors
5. DU-BRO Clevises (Nylon or Steel)
Reliable connectors for pushrods, especially on glow or electric builds.
