Manufacturer bench figures (HGLRC bench, 2450 KV at 16 V (4S) and 24 V (6S), 50% and 100% throttle on each of four 3-4in 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. The product page is titled for the 3500 KV and carries both windings' tables; only the 2450 KV our retail listing sells is reproduced here. The spec-block cross-check lands exactly: HGLRC's 18 A and 432 W for this winding are its GF 4023R*3 24 V 100% row, digit for digit. Source defect reproduced as printed: the GF 4024R*2 24 V pair's Power column is 25 V x current (67.5 W at 2.7 A, 347.5 W at 13.9 A) where its Voltages column prints 24; the other fourteen rows are their own printed voltage x current. The HQ D90*3 24 V block is also the one run on either table whose 50% row prints a LOWER efficiency than its own 100% row (1.755 against 1.832 g/W).
