Manufacturer bench figures (HGLRC bench, 21000 KV at 1S (3.7 V), 50% and 100% throttle on each of five 1.6-2in whoop props); real-world thrust varies with ESC, battery sag and prop condition.

Where this data comes from

The rows are HGLRC's own 'Efficacy table', published as an image in the description gallery of the motor's product page on hglrc.com - the eighth brand this dataset has read a manufacturer sheet from, and the first whose sheet publishes a per-run MOTOR TEMPERATURE. One template across the whole SPECTER line: columns Prop (inch) / Voltages (V) / Throttle (%) / Load Currency (A) / Pull (g) / Power (W) / Efficiency (g/W) / Temperature (in full throttle load 5's). Two throttle points per prop run, 50% and 100%, no RPM column at all, and the temperature is one figure per voltage block measured after five seconds at full throttle, not per row. Full-throttle temperature runs 60 degC on the GF1610R*2 to 83 degC (the sheet labels it 'Hot') on the GF2023R*3. Every row's Power column is exactly 3.7 V x its own current. THIS PAGE'S SPEC FIGURES DISAGREE WITH THEMSELVES: the product page's text block states 13.5 A and 85 W, its Specification IMAGE states 13.3 A and 52 W, and the bench table's largest row is 13.3 A / 49.2 W - so the image's current is the table's own maximum and the text's is not. Neither figure is a field we carry; both are recorded rather than chosen between.
