Manufacturer bench figures (6S, DALPROP Cyclone 5046, 100% throttle, 1900KV; manufacturer bench at fixed thrust points (300/500/700 g) plus max; 2400KV tested on 4S); real-world thrust varies with ESC, battery sag and prop condition.

ECO II Series 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 1450 g is read off each maker's curve, straight-line between its two nearest bench points; 1450 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 EMAX ECO II Series 2207 motors at 2020 g max thrust each give 8080 g: 2:1, the minimum to fly, up to 4040 g all-up; 4:1 (freestyle) up to 2020 g; 8:1 (racing) up to 1010 g.

Where this data comes from

Weight, body, winding, cell rating and resistance from EMAX's own Specifications sheet (2207-2020-10-29-2.jpg) on the maker's product page, read at full size 2026-10-20: one block per winding, each 12N14P, Φ27.5*33.2mm, 4 mm bearing shaft, 20#AWG 120 mm lead, internal resistance 72 / 59 / 41 mΩ (1700/1900/2400 KV), weight 33.4 g at 1700 KV, 33.6 g at 1900 KV, 33.5 g at 2400 KV, every one printed "(W/O Silicone Wire)". EMAX prints no weight with the cable, so weight_g keeps the maker's first-listed sold winding's figure, named on the page as cable excluded. No. of cells per winding as printed: 3-6S at 1700 and 1900 KV, 3-4S at 2400 KV. The drawing gives a Φ16 4-M3 bolt circle (mount_bolt_circle_mm) and an M5 prop thread. The page published 33.5 g, the 2400 KV figure, until 2026-10-20.
