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.
