RCINPower EX4214 Heavy-Lift Motor

The RCINPower EX4214 is a 42mm-stator heavy-lift motor for 13-inch props on 6S, aimed at VTOL aircraft and 13-inch long-range or heavy-lift multirotors. It pulls over 6.5kg per motor at full throttle and runs above 85% efficiency in the 8-15A cruise band for long endurance.

Key features

• 4214 stator in a 12N14P layout, wound at 520KV for 6S

• Up to 6531g thrust per motor on RC1248x3 folding props at 25.2V

• Over 85% efficiency at 8-15A for efficient cruise

• 6mm hollow shaft and 30 x 30mm M4 mounting pattern

• 40cm 16AWG leads reach the ESCs on large frames
