The 4500KV version seems easily to be the best of this line of motors. Higher efficiency at nearly every work load compared with the two higher KV versions leave you with good options to run on 3s if efficiency is your goal, or higher voltages if you're looking for more power. On 3s this motor is comparable with the 7500kv version on 2s, giving a little less thrust with very light prop loads, and a little more thrust with very heavy prop loads. As with the entire lineup it seems to best match a prop load similar to the 3020 biblade, which leaves you running just above the sweet spot of efficiency in static loads, and should give a good spread of efficiency once unloading kicks in in the air. Heavier prop loads like the RotorX 3044 are starting to push the limits of the motor in a static test, drawing around 140 watts, and would rely heavily on unloading in the air to keep power draws down.
