Manufacturer bench figures (BrotherHobby 2022 bench, 6S 80 A ESC, 8 throttle points (30-100%) per winding on one prop each; 1350KV on HQ 8X4.5X3, 1500KV on HQ 7X3.5X3, 1900KV on HQ 6X3.5X3); real-world thrust varies with ESC, battery sag and prop condition.

Where this data comes from

BrotherHobby publishes three Avenger 2808 Test Reports (1350/1500/1900 KV); our listing sells the 1500 KV, whose block gives 48.00 mOhm, 1.69A/10V idle, a 28.00 mm x 8 mm stator and N52H magnets. weight_g is corrected from 54 g to 55.0 g: all three Specification blocks state "Weight Including Cable (g) 55.00" beside "18#, 250mm", where RaceDayQuads prints 54 g. Two source defects reproduced rather than repaired: the 1350 KV sheet's 30% row prints an RPM of "900" where its run is five digits throughout, so that row publishes no RPM; and the 1500 KV sheet's RPM falls from 22117 at 80% to 21634 at 90% while current, thrust and power rise normally
