battery question

[Wayne Galligan]

Now neither one of you indicated if you where using 4 or 5 cell pack.   A 5 cell pack will draw down faster then 4 cell.  Increase voltage to equipment makes them work hard and draws more current.
I  guess everyone's mileage will vary.  I fly the same intermediate pattern twice per flight with a few extra maneuvers thrown in for good measure and I use about 180 mil per flight.  Digital servos and a 1500mil 4 cell NiCad pack.  I fly anywhere from 3-5 flights after 5 flights I still have some reserve but that what it is... a reserve.

  Interesting about current consumption.  I can fly 3 times through the Intermediate pattern, using about 16 oz. of a 24 oz tank, and, after 2 flights, the battery takes 240 mils.  Pretty close to what you have stated for your flying.  Again, my airplane only.

    One thing to keep in mind is "flight" can mean different things to different people. To some, a flight is two times through the masters sequence with a some additional work on a manuever or two. To someone else (like me) a flight is once through the Advanced sequence with work on a couple of manuvers. My typical consumption is 100mAH per flight, which is a valid number only for me flying my airplane, with all equipment functioning properly. With a 1650mAH NiMH pack I am comfortable flying 8 times, roughly half of the pack's capacity. I measure the voltage between flights to gaurd against some unknown such as a binding servo suddenly drawing more current. I recommend you calculate your own "per flight battery consumption" and not rely on other's observations.
