I find it difficult to know the battery power remaining using the indication on the Breeze control. The four little blue LEDs always look the same to me regardless of the status of the battery. I do not see four clearly lit LEDs when fully charged with a downward progression of 4, 3, 2 and finally 1 as the battery power fades. So my question is does the system give you a reliable warning that the battery on the controller is to the point where you need to charge it before you have insufficient battery for safe flight?
