Manufacturer bench figures (Flywoo bench, 6000 KV on six props at 7.4 V (2S) and, on two of them, 11.1 V (3S), 50% and 100% throttle, with the motor temperature after 3 s at full throttle); real-world thrust varies with ESC, battery sag and prop condition.

Thrust-to-weight with this motor

Four Flywoo ROBO 1303 motors at 355 g max thrust each give 1420 g: 2:1, the minimum to fly, up to 710 g all-up; 4:1 (freestyle) up to 355 g; 8:1 (racing) up to 177.5 g.

Where this data comes from

Flywoo's own ROBO 1303 6000KV page (flywoo.net, read 2026-10-23 through the local browser; the description images are on Flywoo's Shopline image host) carries a PRODUCT PARAMETERS bench table (description image 9-en-2.jpeg, 1600x1329): GF2020R*4 and GF D51*4 at 7.4 and 11.1 V, GF2540*3, GF3018*2, GF3018*3 and GF3028*3 at 7.4 V only, 50% and 100% throttle, with no RPM column; the sheet names no KV, and the page sells the 6000 KV winding only. Every row's power is volts times amps; every efficiency is thrust over that power except one, recorded rather than repaired: GF D51*4 at 11.1 V and 100% prints 1.427 g/W, where 355 g over 249.8 W (11.1 V x 22.5 A) is 1.421, so that efficiency cell is left empty while volts, current and thrust stay as printed. Max thrust is that row, 355 g at 22.5 A, marked 85 C after 3 s; the best 2S figure is 337 g on GF3028*3. The parameter block states NSK bearings, 13 x 3 mm stator, 1.5 mm shaft, 2-4S, a 9 x 9 mm mount and 'Weight 6.1g (without wire)', which replaces the retailer's 5.0 g (a maker figure the retailer's is below even without the cable); the maker prints no weight with the cable. The dimensional drawing (8-en.jpeg) gives a Ø16.5 mm bell and a 10.1 mm body length, four M2 holes. The table's props top out at 3 inch, against the retailer's 3-4 inch recommendation, which is left as the listing prints it.
