Manufacturer bench figures (FETtec bench, 1800 KV on four props at 21 and 25.2 V (5S and 6S at 4.2 V/cell), 50% and 100% throttle, with the motor surface temperature after 5 s at full throttle); real-world thrust varies with ESC, battery sag and prop condition.

Where this data comes from

FETtec publishes a one-page datasheet PDF per motor from its own shop (fettec.net, Shopware; the product page's "Verfügbare Downloads" link), and the FM2004T 1800KV sheet is a Technical Datas block, three dimension drawings and a 16-row test table: four props (GF4024R, HQT5*3R, HQT5*2*3R, GF5125R) at 21 and 25.2 V, 50% and 100% throttle each. The sheet prints volts only; 21 and 25.2 V are 5S and 6S at 4.2 V per cell, and its own No.of Cells row reads 4~6S. Identity with the RaceDayQuads listing we price from is the 1800 KV winding, the 20 x 4 mm stator, the 1.5 mm prop shaft and the 4-6S range. The block adds 12N14P, a Ø 25 x 13.7 mm body, a 3 mm inner shaft, 220 mOhm, 0.55 A idle at 10 V and a (0.6-2A)>84% efficiency band. Three source facts recorded rather than repaired. The sheet's Weight row is 15.5 g with 3 cm of wire where FETtec's own shop page and our retail listing both state 17 g, so the published weight stays at 17 g and the datasheet figure is the bare motor. The block's Max Current and Max Continuous Power are labelled 5S but are the 25.2 V (6S) GF5125R 100% row: 13 A and 330 W against that row's 12.7 A and 320.0 W, where the sheet's own 21 V 5S peak is 10.2 A and 214.2 W. And mount_mm stays empty: the bottom-view drawing dimensions 12 mm between opposite holes of a four-M2 cross and our listing calls the pattern "12mmΦ", so the 12 mm is a bolt circle - an 8.5 mm square in the pattern a frame sees - and this file keeps a bolt circle out of that field. Max thrust is the GF5125R 25.2 V 100% row, 1127 g at 320.0 W.
