Rick_H is right, mah is used to estimate voltage if you do not have a guard, if you have a guard then let it do its job. TP says voltage, I think they would know what their talking about. Most guards keep voltage above 3.3v per cell.

Well I just did a hover test in the house with the 10.2V setting and to be honest it was very annoying. It beeps here and there and it didn't take long for it to drive me nuts. I'm going to stick with 9.6V and let the voltage guard do its thing. I'm going to trust the guard (thats why I bought it) and will time my flights from time to time to see where performance ends up.

Sounds like a good plan to me, I don't remember where I heard the 85% mah number, probably from a lot of different posts around here. So, I don't have a concrete source for my information, it just sounds right to me. Personally I don't have that problem because after about 12 minutes of flying, I get a very noticable drop in headspeed, it actually makes my heli start to wobble, then I land and I have never used even most of my pack's mah totals...

But Honey, I can't live with just stock.....

I have this one, great customer service and he will even custom build it for you. There was a no questions asked replacement once for me. I land when it hits yellow.

http://www4.mailordercentral.com/he...p?number=335444 This is where I bought mine from and the directions are the easiest I have come across while dealing with heli. It comes with a one page easy to follow paper on set-up. Like I said I'm going to try 9.6V until I start doing some stick banging then I may have to drop the voltage some. This one I believe is better than the one on ebay because it does both bright led and 88db warning tone. Hope this helps some..

A good rule of thumb for the longest life on your batteries is that the resting voltage should be the same as the nominal voltage of the pack. This mean that if you are lower than 11.1 volts after the pack has sat for 10 mins or longer after a flight then you have discharged it beyond the optimum amount for the longest life.

The number of times you discharge it more deeply than this and how deeply you discharge it will have a direct effect on the overal number of useful cycles you will get out of the pack.

The question here is not really if you are or are not killing your packs because that is a given. We all are. Every time you use them that is one cycle gone out of a limited number of cycles. No manufacturer claims that their cells will last forever because they dont. Each cell has a limited number of useful cycles so we are all killing our packs. Some of us just more quickly than others.

To directly address the original poster:

If you are getting enjoyment from the way you are cycling your cells and happy with the 14 mins of flight time than thats all that really matters. You will get many more cycles out of your packs than the guy who flies till his ESC initiates the LVC routine but maybe a bit less than the especially careful guy who flies for 10 minutes and lands every time and ends up with a resting voltage of 11.1 volts or greater. However we pay for enjoyment so its a trade off. If less cycles on a pack means more enjoyment for your dollar than so be it and be happy!
