Ken,

You wrote"A normal 4 channel .40 size airplane with 4 standard Servos will pull approximately 250 mAh
per hour of constant use. For many Years, Radio manufacturers use standard 600 mAh batteries in the Transmitter and Flight pack. This gave a TOTAL of about 2 Hours of Flying Time before the batteries required a re-charge. 600 mAh / 250 mAh = 2.4 Hours of battery life."

My 600 mah was giving my 4-servo planes 3 flights of about 8 minutes each. This is why I just switched to 1,100. So there must be something wrong on both of my planes.

Also, you mentioned to cycle a few time to determine capacity. How do you determine the capacity? I have a regular Hangar 9 voltmeter with 3 levels 2A, 1A and .5A. Whicj one should I use?

Thanks,
