Greetings, My phantom seems to fly OK (only had one flight so far) but I am curious about the rotational resistance of the motors. I noticed that when the props start to rotate upon power up, the two left ones (as you face the battery) start just a fraction of a second later than the right ones. Same thing on power down. They stop before the right ones. Not by much, just a very short interval of time. So I tested the rotation of each of them by spinning the manually with my finger using the same amount of force. Indeed, the two left ones have more resitance than the right ones. Anyone else? Thanks.
