I just noticed that one of the propellers on the DJI phantom 2 is not spinning as fast as the others. I switched around the white propellers and it seemed to improve a little but looks like it's still slower than the other three. You can see when it's idling, the propeller slows then speeds up and the LED for the propeller blinks. This happens when the battery is around 50% or lower. At full charge it doesn't happen. The phantom is hovering well and flying well it's just that when it's idling that motor is not spinning as fast as the others. Is this a problem, should I be concerned?
