Description: 【Suitable for 】: This differential airspeed tube is   for airspeed measurement and flight control,  ensuring optimal performance  in airspeed measurement 【Installation Guidance】: Thread the tubes through the foam in front of the cockpit . Ensure side holes are unobstructed and extend at least 1cm from the nose. Connect silicone tubes from the straight tube to the upper port and from the bent pipe to the lower port on your pressure 【Propeller Consideration】: If your aircraft has a front propeller, mount the dynamic tube on a wing or below the fuselage to avoid prop wash interference, while static tubes can be placed anywhere convenient 【Operational Check】: Use Planner or other ground stations read airspeed . Blowing into the tube should show responsiveness; or small oscillations (2-3) in still air are normal due to minimal pressure changes at low speeds 【Sturdy Construction 】: Made of metal for durability,  Airspeed Meter Gauge Differential Pitot Tube  is sturdy for long term use  Size Chart: Y Type Airspeed tube 10cm/3.94inch Package Includes: 1 Y Type Airspeed tube   1 Pitot tube Note: Please allow slightly errors 1-2cm/0.39-0.79inch differences due to manual measurement.
