Manufacturer bench figures (Foxeer bench, both windings over the same four 3-4in props: 3850 KV at 11.1 and 14.8 V (3S/4S), 4533 KV at 7.4 and 11.1 V (2S/3S), 50% and 100% throttle; no RPM published); real-world thrust varies with ESC, battery sag and prop condition.
Thrust-to-weight with this motor
Four Foxeer Datura 1404 motors at 423 g max thrust each give 1692 g: 2:1, the minimum to fly, up to 846 g all-up; 4:1 (freestyle) up to 423 g; 8:1 (racing) up to 211.5 g.

Where this data comes from
Bench rows are Foxeer's own two test sheets, headed "DATURA 1404-3850KV" and "DATURA 1404-4533KV", the description images of Foxeer's former product page for this motor (foxeer.com goods 399, "1404 - 4533KV/3850KV", read in its Web Archive copy; the images are still served by inew.foxeer.com). The 4533 KV winding is this motor and no listing of ours sells it now, so it is added to the KV list off the maker's own sheet (RaceDayQuads once listed it as "4553Kv"). Each sheet carries its own Technical Datas block and each block's two maxima land on its own DAL T3028 full-throttle row - 226 W / 15.3 A at 3850 KV (226.4 W at 14.8 V, under a "3S" label that row contradicts), 164 W / 14.8 A at 4533 KV (164.3 W at 11.1 V). Every other row's Power is its own Voltages x its own Load Currency and every printed Efficiency is its own Pull / Power. Three rows print a Power their own volts and amps contradict, so their current and efficiency are left blank (thrust kept): 3850 KV DAL T3018 at 14.8 V prints 2.3 A / 25.5 W at 50% (14.8 x 2.3 = 34.0 W) and 12.5 A / 138.8 W at 100% (185.0 W; 138.8 W is the 4533 KV sheet's own 11.1 V x 12.5 A cell), and 4533 KV GF4*2*2 at 11.1 V 50% prints 4.1 A / 30.3 W (45.5 W). The 3850 KV sheet prints GF4*2*2's 14.8 V run empty; it is left out. The blocks rate the windings 3S-4S and 2S-3S and give 240 / 140 mOhm, where the listing prints the 3850 KV figure as "240Ω". Both blocks: 9N12P, 14x4 mm stator, Phi 19.2*16.9 mm, 9 g with 3 cm wire, 1.5 mm shaft (2 mm inside), 9 mm square 4 x M2 mount on the drawing. Temperature after 3 s at full throttle: 53-80 degC at 3850 KV, 55-80 degC at 4533 KV, DAL T3028 at the higher voltage marked HOT on both.
