Manufacturer bench figures (Flash Hobby bench, three 7in props at 23.9-24.7 V (6S), 40-100% throttle in 10% steps, with RPM); real-world thrust varies with ESC, battery sag and prop condition.

Arthur 2807 vs other 2807 motors on 6S

The same thrust costs different power on different motors. Each line is one maker's own bench series (6S, its own prop), drawn as grams of thrust per watt against thrust, so a higher line makes that thrust for less battery current. Throttle percent is left out on purpose: it means something different on every maker's rig.

Power at 1000 g and 2000 g is read off each maker's curve, straight-line between its two nearest bench points; 2000 g is the highest thrust every motor here reached. Different props and rigs move these curves as much as the motor does, so compare rows on a similar prop. Peak thrust of every 2807 motor: 2807 motors compared.

Thrust-to-weight with this motor

Four Flash Hobby Arthur 2807 motors at 2036 g max thrust each give 8144 g: 2:1, the minimum to fly, up to 4072 g all-up; 4:1 (freestyle) up to 2036 g; 8:1 (racing) up to 1018 g.

Where this data comes from

Bench rows are Flash Hobby's own test table, headed "A2807-1300KV", published as a description image on this retail listing; flashhobby.com publishes no bench table for any FPV motor. The image begins at the table's first data row - the header is not in it - so the columns are read off the arithmetic instead: Power is each row's own volts x amps to 0.15 W on all 21 rows (the GF7*3.5*3 60% row, 24.54 x 16.89 = 414.38 against a printed 414.5, is the only one past 0.05), printed Efficiency is Thrust / Power on all 21, and the one column left is five digits and monotone in throttle on each run, in the slot the brand's own Arthur 2207.5 sheet leaves out - RPM. The listing's "Max pull: 1996g" is this table's GF7*4*3 full-throttle row to the gram, not its maximum: the GF7*3.5*3 run reaches 2036 g. Operating temperature: 55.8 degC on GF7*3.5*3, 52.4 on GF7*4*3, 60.6 on GF7042.
