The high-altitude low-noise propellers guarantee flight performance at high altitudes of 3,000-7,000 m, and the noise of the blades is reduced by 2 decibels compared with the standard 2110s propellers.

• Using high-altitude propellers for extended periods may reduce the motor life and the max payload capacity of the aircraft.
• If there is any damage to a propeller, replace it immediately.
• When replacing the propellers, please also replace the corresponding screws and attach a proper amount of threadlocker (thread locker 243 is recommended) to the surface of the new screws. 
• DO NOT mix the 2112 propellers and other types of propellers during use.
• The 2112 propellers are compatible with the Matrice 350 TRK and Matrice 300 RTK.
