Thanks for all the info but I knew all the theory. The fact is that I dodn't exactly know the voltage when I decide to stop flying and disconnect the battery. That's why I ask the most experienced of you to inform me how DO YOU discharge your Lipos during flight.
Do you have measured a specific time at which, (during hover) the heli must have the pack discharged SAFELY ? e.g. 2 cells NOT LESS than 6 V.

Plus how many mAh does YOUR charger give to the pack, (each time you charge), relatively to their labled capacity ? e.g. My pack is labeled 1200 mAh. Each time I recharge it doesn't get more than 900 to 920 mAh. Is this normal according to your experience ?

Thanks again,
Michael.
