10x3 RC Propeller Spare Blade APC AP1003  [AP1003]

APC AP1003 10x3 Propeller Details

The APC AP1003 PROPELLER 10x3 serves as an aftermarket spare or simple tuning blade for electric hobby aircraft. The 10x3 label identifies diameter and pitch, which together influence how the prop trades off thrust against RPM; this item is supplied strictly as an accessory for RC applications.

Installation is typical for small electric powerplants: mount the blade on the correct shaft or adapter, ensure true seating, and secure the spinner or nut to the motor maker's torque guidance. Check rotation direction and confirm adequate clearance so the prop does not touch the fuselage or control surfaces at full throttle.

From a tuning and usage perspective the 10x3 profile offers moderate thrust without heavily loading the motor, providing predictable RPM behavior useful in testing. If you alter pitch or diameter, monitor motor temperature and ESC draw to maintain safe operating conditions.

Maintenance tips: inspect for chips, cracks, and laminate separation before each flight, static-balance after repairs or impacts, and replace any blade that shows warping or structural damage. Use a compatible adapter and correct mounting hardware to avoid runout.
