As winter fades and flying season approaches, it’s the perfect time to inspect your RC airplanes and helicopters for hidden “gremlins.” Whether you store your models all winter, fly off the snow with skis, or escape the cold to fly year-round, maintenance is essential. Cold temperatures, moisture, vibration, and hanger rash can weaken essential components—especially your control system. A quick spring inspection can save your model from avoidable mid-air failures and help you enjoy smoother, safer flying all season.
DU-BRO parts are known for being durable and long-lasting, but even the best hardware can suffer from age, storage conditions, or accidental bumps. That’s why DU-BRO always recommends a seasonal checkup focusing on three main questions: Is it secure? Is it broken? Is it sticky?
For replacement hardware or upgrades during your inspection, DU-BRO offers a full line of high-quality parts designed for RC reliability.
Is It Secure?
Start by inspecting every part of the control system:
-
Servo screws: Ensure all are present and properly tightened. Loose screws lead to sloppy control response.
-
Servo horns: Confirm they are firmly attached. A loose horn can cause immediate loss of control.
-
E/Z Connectors: Make sure they rotate freely and are firmly secured.
-
Snap Washers: These tiny retainers can wear out or loosen—replace any that look questionable.
-
Flexible Pushrods (like DU-BRO Lazer Rods): Make sure the sleeves and exit guides are fully glued and anchored.
Next, give each control surface a firm but gentle tug. Hinges can loosen over time, especially nylon or CA hinges exposed to cold or moisture. If anything feels loose, replace it before your next flight.
Is It Broken?
Winter can be hard on RC equipment. A knock in the workshop, a minor crash, or even shifting storage boxes can damage fragile parts like:
-
Control horns
-
Clevises
-
Pushrods
-
Plastic hardware
-
Wood airframes
Even if DU-BRO parts are tough, they’re not indestructible. If anything looks cracked, rusty, or bent, replace it now—it’s far cheaper than repairing a crashed airplane.
Float flyers or models stored in damp environments should pay extra attention. Rusty clevises, corroded pushrods, and moisture-swollen wood can all lead to disaster. Swap out anything compromised before flying.
Is It Sticky?
Smooth, unrestricted movement is essential for precise flying. Sticky controls can indicate:
-
Binding hinges
-
Warped wood
-
Dirty servo gears
-
Stripped gear trains
-
Failing servos
-
Misaligned pushrods
Disconnect your pushrods and manually move each control surface through its full range. Fix any resistance or stiffness—you won’t magically solve these issues in the air.
For new pushrods, clevises, or linkages, DU-BRO offers high-quality replacements designed for longevity and smooth operation.
Enjoy a Trouble-Free Flying Season
An annual control-system inspection helps prevent crashes, protects your investment, and keeps your aircraft performing at its best. With a methodical look at your RC model and reliable DU-BRO hardware on hand, you can chase away those winter gremlins and take to the skies with confidence this spring.
