This is a custom 3D‑printed motor mount designed for the Langyu 2216 (SUNNYSKY) motor, primarily used in model aircraft—such as fixed-wing aircraft—to securely mount the motor onto the airframe.

Core Functions

• Precise Mounting: By utilizing pre‑drilled motor mounting holes, the motor is precisely positioned on the airframe, ensuring perfect coaxial alignment between the motor shaft and the propeller and preventing vibrations caused by misalignment.

• Structural Support: Serving as a rigid connection between the motor and the airframe, this mount transmits the motor’s torque and thrust while absorbing impact forces during flight, thereby protecting the motor shaft and bearings.

• Space Optimization: Tailored to the specific spatial layout of the aircraft, the design carefully plans motor placement and cable routing to create a more compact airframe with a balanced center of gravity.

Design Features

• Precision Fit: The mount is modeled based on the exact mounting hole spacing and dimensions of the Langyu motor, ensuring a snug, vibration‑free fit that eliminates any play or looseness.

• Lightweight Construction: Employing hollowed-out and truss‑like structural designs, the mount achieves maximum weight reduction while maintaining robust strength and rigidity, minimizing any adverse impact on the aircraft’s flight performance.

• Enhanced Heat Dissipation: The extensive use of open‑air channels significantly improves airflow, enabling rapid heat dissipation even under high‑load conditions—boosting motor efficiency and extending its service life.

• Durable Materials: It is recommended to use high‑strength 3D‑printing materials such as nylon or carbon‑fiber‑reinforced PETG, which offer excellent impact resistance and fatigue durability, making them ideal for demanding flight environments.

Application Scenarios

• Power system upgrades and modifications for fixed‑wing model aircraft.

• Motor installation for aircraft with unconventional configurations, such as tail‑rotor or pusher‑propeller layouts.

• Racing or aerobatic aircraft models where weight and structural integrity are critical factors.
