Where this data comes from
Bench rows are Flash Hobby's own test table, headed "A2207.5-2500kv", published as a description image on this retail listing; flashhobby.com publishes no bench table for any FPV motor. The table carries no spec block of its own - the listing's does the cross-checking, and its "Max pull: 1590" is this table's Gemfan 6045x2 full-throttle row to the gram. The Volts column prints a flat nominal 16 on all twelve rows, but each row's own Power is 16.29 x its current, to 0.05 W on every row of both runs, so 16 is the pack's nominal voltage and not the bench's; the voltage is carried as printed and the efficiency column is the sheet's own thrust / power. Operating temperature: 59.3 degC on the DAL 5047 3R run, 68.2 degC on the Gemfan 6045x2 run.
