MEPS SZ2306 V2

What it pulls

MEPS’s own bench test, one line per prop. Drag across the chart to move the throttle; the model above follows.

What you get for $12.90

• Thrust data for every KV

  Full throttle with the SZ5145: 1734.6 g (1750KV) and 1815.4 g (1950KV) on 25.2 V, 1468.5 g (2450KV) on 16.8 V.

• Fewer, thicker arms

  MEPS says V2's bell has fewer but thicker supports than V1, for crash resistance and cooling, and an anti-slip prop mount.

• Titanium shaft, NMB bearings

  A TC4 titanium alloy shaft and NMB bearings; MEPS gives a service life of up to 10,000 hours.

What to pair it with

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

ESC

MEPS pairs it with 45–60 A ESCs. Its peak currents are 33.1 A (1750KV), 42.7 A (1950KV) and 39.8 A (2450KV), and its full-throttle tests reach 46.3 A (1950KV) and 43.2 A (2450KV) with the SZ5145. (MEPS product page, MEPS spec table, MEPS data test)

Props

MEPS tested its SZ5145 and SZ4942 three-blade props; the SZ5145 pulls 168–184 g more at full throttle, depending on KV. (MEPS data test)

Battery

6S for 1750KV and 1950KV, 4S for 2450KV; MEPS's FAQ also allows 4S for the 1950KV. (MEPS spec table, MEPS product page)

Frame

Four M3 screws on a 16 mm circle (the 16 × 16 pattern of 5-inch frames); M3×8 and M3×9 screws come in the box. (MEPS size chart, MEPS package list)

Bench data

Redrawn from MEPS’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. Fewer but thicker structural supports than the first version, which MEPS says strengthens the rotor and helps cooling under load. (MEPS product page)
• Winding. MEPS says V2 rearranges the windings to fit more conductor into the motor than V1. (MEPS product page)

How fast it spins

KV is the motor’s no-load speed per volt. With nothing on the shaft, the 1950KV 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 MEPS’s published sizes: the 23 × 6 mm stator, 29.3 mm bell, 18.55 mm height, 5 mm shaft, 16 mm mounting circle and 12 teeth and 14 magnets. Anything MEPS 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.
