Manufacturer bench figures (6S, EMAX AVAN 5026-3, 100% throttle, 1900KV; manufacturer payload test, 8 load points per KV; 2400KV tested on 4S); real-world thrust varies with ESC, battery sag and prop condition.

E3 Series 2306 vs other 2306 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 1300 g is read off each maker's curve, straight-line between its two nearest bench points; 1300 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 2306 motor: 2306 motors compared.

Thrust-to-weight with this motor

Four EMAX E3 Series 2306 motors at 1760 g max thrust each give 7040 g: 2:1, the minimum to fly, up to 3520 g all-up; 4:1 (freestyle) up to 1760 g; 8:1 (racing) up to 880 g.

Where this data comes from

Weight, body, winding, cell rating and resistance from EMAX's own Specifications sheet (ECO-111-20250308---__10.jpg) on the maker's ECO III product page, read at full size 2026-10-20 (EMAX sells the E3 series as ECO III, the same motor): one block per winding, each 12N14P, Φ28.9*31.8mm, 4 mm bearing shaft, 20#AWG 120 mm lead, internal resistance 79 / 66 / 47 mΩ (1700/1900/2400 KV), weight 29.4 g at 1700 and 1900 KV, 29.5 g at 2400 KV, every one printed "(W/O Silicone Wire)"; the retail listing repeats the same figures "without silicone wire". EMAX prints no weight with the cable, so weight_g keeps the maker's first-listed 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 listing's "Mounting Pattern: 19x19mm" is not a square pattern on EMAX's drawing, so mount_mm is not published.
