Where this data comes from
The sheet is RC IN POWER's own test-report template (its footer prints [email protected]) under the AOS RC name, and it is the description image on this retail listing; rcinpower.com's own G-SERIES index publishes no AOS 1605 at any id. It is headed "MOTORS: AOS 1605 -3900KV" and its Technical Datas block is the listing's Specifications block to the digit - 9N12P, 16 mm stator diameter, 5 mm stator length, 1.5 mm shaft (2 mm inside), 13.3 g with 3 cm wire, idle 1.26 A at 10 V, 3S-4S, 616 W max continuous, 38.5 A max current - plus one figure the listing omits, an internal resistance of 88 mOhm. It also settles a figure the listing mistypes: the body is Phi 20.3*14.2 mm, which the listing prints as "20x3 x 14.2mm". The block's maxima are its own Gemfan D90*5 full-throttle row (616.0 W / 38.5 A), under a "3S" label that row contradicts: every one of the twelve rows is at 16 V (4S). The base mount is 9x9 mm 4xM2, its two callouts drawn across the diagonals; the 5x5 mm pattern on the bell is the prop pattern. Temperature after 3 s at full throttle: 73-85 degC, the Gemfan D90*5 run marked "HOT" by the sheet itself
