What to pair it with

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

ESC

GEPRC recommends a 12–20 A ESC. Its bench peaks at 10.6 A at full throttle on 7.4 V. (GEPRC product page, GEPRC drawing and data sheet)

Props

GEPRC tested six Gemfan props at 7.4 V, from the GF1608R*3 (144 g at full throttle) to the GF45mm*3 (174 g). (GEPRC drawing and data sheet)

Battery

2S (7.4 V). (GEPRC product page, GEPRC spec image)

Frame

Three M1.4 holes on a 6.6 mm circle; GEPRC says it suits 1.6 to 2-inch lightweight models. (GEPRC product page, GEPRC drawing and data sheet)

Bench data

Redrawn from GEPRC’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:

• Bell. One-piece CNC-machined 7075 aluminium, matte black with polished edges and large openings, over N52H arc magnets. (GEPRC product page, GEPRC features image)
• Stator. Kawasaki 1200 steel, 9N12P, wound with multi-strand copper wire. (GEPRC product page, GEPRC features image)
• Bearings. NMB bearings. (GEPRC product page, GEPRC features image)

How fast it spins

KV is the motor’s no-load speed per volt. With nothing on the shaft, the 14800KV 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 12-pole rotor has 6 pole pairs, so every turn of the shaft is 6 electrical cycles, and a six-step ESC switches the phases 36 times per turn.

About the 3D model

A generic outrunner drawn from GEPRC’s published sizes: the 10 × 3 mm stator, 13.6 mm bell, 8.7 mm height, 1.5 mm shaft, 6.6 mm mounting circle and 9 teeth and 12 magnets. Anything GEPRC 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.
