Obviously you can bring it up or down depending on what you do and what your setup is. That being said i don't find the type/brand of servo makes a massive difference. Flying style makes a difference - constant maxed out flying uses more obviously.

I don't think with nickel batteries you really want to go too far below half charge (IMHO).

Per the advice above I don't find f3b flying uses too much battery. Although there is really no need to have flat batteries if you are winching as you have lead 12v batteries and chargers on site all the time.

I agree that something in the order of 2 hours is reasonable. Assuming no binding servos and such!
Thanks to all for the feedback.

My particular model has a good size motor/esc/lipo up front. This makes the plane tend to be nose heavy. After placing mock-up pack (7ozs.) on the boom, it looks like I will need the heavier stick pack way down the boom.

I just ordered 2 different packs to try. One being a 2700mah, and the other a 4000mah. These give me the weight and dimensions I need with mah to spare. So no concerns on capacity

Thanks, Bill

Thanks guys got the X and its real nice, It already has a 1500 elite 4 cell in it, and an airtronics10 ch receiver.I have cycled the battery twice and its coming up at 1240 mh not too bad. I guess i will just get an SD-10 g radio.Maybe someone has a set up they can send once I get a radio. Thanks for all the help! Jack.

Jack,
What discharge rate are you cycling your pack at? It should be cycling at closer to
1500 with a discharge load of 250 mA to 500 mA. A new pack is cheap insurance...
