Manufacturer bench figures (Foxeer bench, T-Mount version: 2650 KV over six 3.5-5in props at 11.1, 14.8 and 22.2 V (3S/4S/6S), 3650 KV over four at 11.1 and 14.8 V (3S/4S), 50% and 100% throttle; no RPM published); real-world thrust varies with ESC, battery sag and prop condition.

Where this data comes from
Bench rows are Foxeer's own two test sheets, headed "DATURA 2105.5-2650KV" and "DATURA 2105.5-3650KV", on the one 1080x5100 description image of Foxeer's former product page "DATURA 2105.5 (T-Mount)" (foxeer.com goods 458, "2650KV/3650KV", read in its Web Archive copy; the image is still served by inew.foxeer.com). This page's listing is that T-Mount motor: its gallery is goods 458's, and its spec block (2650 KV, 12N14P, 20.5 g, 1.5 mm shaft out) is the sheet's; Foxeer's other 2105.5 (goods 398, M3/M5 shaft, 1650/2950 KV) is a different motor. The 3650 KV winding is this motor and no listing of ours sells it, so it is added to the KV list off the maker's own sheet. Each block's two maxima land on its own DAL 3528*3 full-throttle row - 742 W / 33.4 A at 2650 KV (741.5 W at 22.2 V), 543 W / 36.7 A at 3650 KV (543.2 W at 14.8 V) - under a "3S" label those rows contradict. Every row's Power is its own Voltages x its own Load Currency and every printed Efficiency is its own Pull / Power. The blocks rate the windings 3~6S at 2650 KV - where the listing says 4-6S; the maker's own 11.1 V runs are on the sheet - and 3~4S at 3650 KV, with 67 / 45 mOhm (the listing prints "67Ω"). Both blocks state the body as Phi 25.53*15 mm (the drawing agrees; the listing prints 25.3x15.4) and the shaft as 3 mm inside, 1.5 mm out (drawing Phi 1.50), 20.5 g with 3 cm wire, mount 12 mm square 4 x M2. Temperature after 3 s at full throttle: 51-80 degC at 2650 KV, 61-83 degC at 3650 KV, GFD90*3 and DAL3528*3 at 14.8 V marked HOT.
