When I started using a BEC last year that was rated for only 2.5 amps folks were generally concerned about that not being enough. I have a sensor that flashes usage which told me I was never exceeding one amp but haven't been able to get sharable data until today when I finally setup my EagleTree with a servo sensor, and here's the graph as promised. Suffice to say that for Intermediate level flying we never go over 1 amp total. This graph is the output of the BEC and represents the sum of all servos together. Also I should mention this corroborates work done a couple years ago by another flyer. I'll try to find the link later. Now of course the trick will be to get a Master's level pilot to fly my plane in a Master's Sequence and then look again
