The DU-BRO Micro Aileron System is a compact, high-precision solution designed to give small RC aircraft accurate, smooth aileron control. Because the kit includes many tiny components, it can feel overwhelming at first glance—but with the right tools and a methodical approach, installation becomes quick, clean, and dependable.
This MasterClass-style tutorial breaks down the process into clear, manageable steps so you can set up your model correctly the first time. Whether you're upgrading an older aircraft or building a new micro model from scratch, this guide will help you navigate the system confidently.
Tools You’ll Need (and Why They Matter)
To get started, you’ll need simple but essential tools:
-
Needle-nose pliers
-
Regular pliers
-
Small screwdriver
-
Fine-tip marker
-
Wire cutters
-
Optional: extra 0.032" music wire for longer pushrod runs
For builders who prefer precision, the DU-BRO E/Z Bender Tool makes forming cleaner bends and installing link stoppers far easier:
Always wear safety glasses when cutting wire—tiny metal pieces can spring unpredictably.
Understanding the Parts & Preparing the Assembly
The Micro Aileron System includes:
-
Torque rods
-
Plastic bearing tubes
-
Clip-in E/Z links
-
Screws, link stoppers, and molded hardware pieces
Before cutting anything, lay out the parts and reference the product card. Measure the torque rod length carefully, then cut the bearing tubes to match.
A helpful trick: use DU-BRO Tru-Cut Scissors for cutting tape and trimming covering near the hinge line without tearing the film:
Installing Torque Rods & Bearing Tubes
-
Bend a 90-degree angle at the end of each torque rod using needle-nose pliers.
-
Mirror the rods! You want a left and right—not two of the same.
-
Transfer them to the wing and mark any excess wire with a fine-tip marker.
-
Cut the rods so they stop flush without protruding from the wing.
-
Set both 5/64" hex-head screws into the clevis hardware, leaving them slightly loose for later adjustments.
For smooth, durable hinging, many builders also install DU-BRO Hinge Tape—strong, flexible, and designed for small control surfaces.
Mounting the Aileron System to the Wing
Secure the bearing tubes onto the wing at the exact hinge line. You can use temporary tape during alignment, then finalize the installation with DU-BRO Hinge Tape for a clean, permanent hold.
Next:
-
Mark your pushrod length.
-
Cut using wire cutters.
-
Install into the micro clevis.
-
Snap the E/Z link clip into place.
If your model requires a Z-bend instead of connectors, use the technique shown in the DU-BRO 101 video. For perfect bends every time, many pilots rely on DU-BRO’s E/Z-Bender Tool
Final Centering, Adjustments & Pre-Flight Checks
Once both ailerons are connected:
-
Remove the prop for safety.
-
Power the airplane.
-
Move the aileron stick and ensure equal deflection on both sides.
-
Center the ailerons by gently twisting the torque rod—small movements go a long way.
-
Tighten the 5/64" screws to lock in adjustments.
Before every flight, inspect:
-
Tape adhesion
-
Clevis tightness
-
Pushrod binding
-
Bearing tube stability
For long-term durability, lubricate the torque rods with DU-BRO’s Lazer Rod to keep movements friction-free:
