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.

Avenger 2808 vs other 2808 motors on 6S

The same thrust costs different power on different motors. Each line is one maker's own bench series (6S, its own prop), drawn as grams of thrust per watt against thrust, so a higher line makes that thrust for less battery current. Throttle percent is left out on purpose: it means something different on every maker's rig.

Power at 1250 g and 2500 g is read off each maker's curve, straight-line between its two nearest bench points; 2500 g is the highest thrust every motor here reached. Different props and rigs move these curves as much as the motor does, so compare rows on a similar prop. Peak thrust of every 2808 motor: 2808 motors compared.

Thrust-to-weight with this motor

Four BrotherHobby Avenger 2808 motors at 2469 g max thrust each give 9876 g: 2:1, the minimum to fly, up to 4938 g all-up; 4:1 (freestyle) up to 2469 g; 8:1 (racing) up to 1234.5 g.

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. max_thrust_g is the sold winding's own best (owner ruling 2026-10-20: it comes from a winding the page sells; rows of other windings stay).
