What to pair it with

Our reading of RCinPower’s numbers, so your build matches what the motor was tested with.

ESC

RCinPower rates the 1980KV at 46.3 A and the 2500KV at 57.8 A. On its bench the 1980KV drew up to 47.2 A on 6S and the 2500KV up to 57.8 A on 4S. A 50 A ESC covers the 1980KV; the 2500KV on 4S needs 60 A. (RCinPower 1980KV sheet, RCinPower 2500KV sheet)

Props

Tested on the Gemfan 5136 and 51466, HQProp R36 and R38, and DALProp T5148.5. The Gemfan 51466 pulled the most on both KVs: 1,948 g on 6S (1980KV) and 1,758 g on 4S (2500KV). (RCinPower 1980KV sheet, RCinPower 2500KV sheet)

Battery

5S–6S for the 1980KV, 3S–4S for the 2500KV. (RCinPower 1980KV sheet, RCinPower 2500KV sheet)

Frame

Four M3 screws, opposite holes 16 mm apart (16 × 16). (RCinPower 1980KV sheet)

Bench data

Redrawn from RCinPower’s test reports. Thrust is static pull on a bench, more than you get in flight. Power is volts × amps; efficiency is thrust divided by power.

Inside the motor

A brushless outrunner: the coils stand still in the middle and the magnets spin around them. From the top down:

• Shaft. 4 mm hollow; 5 mm across the thread, which stands 13.1 mm above the bell. (RCinPower 1980KV sheet)
• Stator. The coils are wound on a stack of thin steel laminations: 22 × 7 mm (2207). (RCinPower 1980KV sheet)
• Base. 4 × M3 holes, opposite holes 16 mm apart (16 × 16). (RCinPower 1980KV sheet)

How fast it spins

KV is the motor’s no-load speed per volt. With nothing on the shaft, the 1980KV version reaches about these speeds; a prop loads the motor and brings it down, typically to around 70–75% of these figures at full throttle.

A 14-pole rotor has 7 pole pairs, so every turn of the shaft is 7 electrical cycles, and a six-step ESC switches the phases 42 times per turn.

About the 3D model

A generic outrunner drawn from RCinPower’s published sizes: the 22 × 7 mm stator, 27 mm bell, 18.65 mm height, 5 mm shaft, 16 mm mounting circle and 12 teeth and 14 magnets. Anything RCinPower doesn’t publish is typical for a motor this size, and the bell’s spoked top, the base and the inside are a generic design, not this motor’s. The colours are read off the maker’s product photos. There are no logos or markings: it is our drawing, not the maker’s.
