DU-BRO Micro Razor Control Horn – Lightweight Horns for Park Flyers

The DU-BRO Micro Razor Control Horn is a lightweight, strong, and easy-to-install control horn designed for medium-size indoor airplanes and park flyers. Small electric models need hardware that is light enough to avoid adding unnecessary weight, yet strong enough to deliver precise and reliable control. This control horn does exactly that.

Its open-frame design keeps the weight extremely low while still giving the horn the strength needed for everyday flying and aerobatics. Even though it weighs only 0.49 grams, it provides solid, dependable linkage support that won’t flex or loosen during flight.

Each horn comes with a bottom support plate that sandwiches the control surface, giving you a firm and secure mount. This helps prevent wiggle or flutter and ensures smooth, accurate control responses. The horn also includes two adjustment positions, making it easy to fine-tune your control throw. Whether you want more movement for aerobatics or a softer response for slow, gentle flying, you can set it the way you like.

With an overall height of 0.8125" (13/16" or 20.64 mm), the Micro Razor Control Horn is sized perfectly for foamies, micro 3D planes, indoor aerobats, and lightweight park flyers. It’s also great for scratch-built designs where every gram matters but reliability is still important.

Each package includes two horns, giving you everything you need for elevators, rudders, ailerons, or other small control surfaces.

Ideal for:

• Indoor and outdoor park flyers

• Slow flyers and foamies

• Micro 3D aircraft

• Lightweight electric models

• Custom and scratch-built micro planes

The DU-BRO Micro Razor Control Horn offers an ideal balance of strength, weight, and adjustability—helping small RC aircraft fly smoothly, accurately, and with confidence.
