 All Hobbywing propeller products have a serial number marked on each set, and products with the same serial number are weight and balance-matched.
 If you mix products with different serial numbers, the balance may be off and vibration may occur.
 If the vibration becomes severe, it may affect the FC and thus the flight, so please be sure to use a set of products with the same number.
