Manufacturer bench figures (iFlight data sheet per winding, 6 throttle points (50-100%) on Nazgul R5 V2, HQ R37 and Gemfan 51466: 1590 KV at about 32 V, 2050 KV at 6S (25.2 V)); real-world thrust varies with ESC, battery sag and prop condition.

R5 2207 vs other 2207 motors on 6S

The same thrust costs different power on different motors. Each line is one maker's own bench series (6S, its own prop), drawn as grams of thrust per watt against thrust, so a higher line makes that thrust for less battery current. Throttle percent is left out on purpose: it means something different on every maker's rig.

Power at 1700 g is read off each maker's curve, straight-line between its two nearest bench points; 1700 g is the highest thrust every motor here reached. Different props and rigs move these curves as much as the motor does, so compare rows on a similar prop. Peak thrust of every 2207 motor: 2207 motors compared.

Thrust-to-weight with this motor

Four iFlight R5 2207 motors at 2108 g max thrust each give 8432 g: 2:1, the minimum to fly, up to 4216 g all-up; 4:1 (freestyle) up to 2108 g; 8:1 (racing) up to 1054 g.

Where this data comes from

iFlight's own shop sells no R5 2207 motor today (its Mach R5 pages are frames and parts), but its image folder held one data sheet per winding, 'R5 2207 1590KV-Data-N.png' and 'R5 2207 2050KV-Data-N.png' (2759 px wide, read from the Web Archive copies of 2025-09-02; the live files now 404): per winding a spec table, the drawing and an 18-row datasheet on Nazgul R5 V2, HQ R37 and Gemfan 51466 at 50-100%. They confirm both windings, 12N14P, 16*16 M3 holes, a 5 mm shaft protruding 12.5 mm, 150 mm 20AWG leads, N52H magnets and NSK 9x4x4 bearings; interphase resistance 95.6 mOhm (1590KV) and 56.3 mOhm (2050KV). Weight with wire is 33.8 g (1590KV) and 34.6 g (2050KV); the page shows the first-listed winding's 33.8 g, named beside it. Both Dimension lines (28.18*31.5 and 28.2*31.5 mm) are the drawing's 19 mm body plus the 12.5 mm shaft, so the body is published as the drawing's Ø28.18x19. The 1590KV sheet was benched at about 32 V (Input Volts 32V), which is not a whole number of 4.2 V cells, so its rows carry no cell count and max_cells keeps the retailer's 6S; the 2050KV sheet is at 25.2 V (6S). All 36 rows pass printed power = V x A and the efficiency identity, and each sheet's Peak Current / Max Watt (38.62 A / 1221.6 W, 49.53 A / 1166.4 W) is its own Nazgul R5 V2 100% row. Max thrust is 2108 g, 2050KV on a Gemfan 51466 at 6S. The same folder holds a third sheet, R5 2207 2100KV, a winding our listings do not sell; it is not reproduced. Per-run temperatures as printed: 1590KV 150/157/153 C, 2050KV 71/69/75 C (Nazgul/HQ/Gemfan).
