If you already have the battery, just plug it in fully charge it, run two flights, then fully charge it again. The charger will tell you how many mAh that it put back in and that's how much you used of two flights. If you're really worried fly one flight then measure how much you put back in. If you fly two flights and put 1000mAh back in then it's pretty safe you'll use 2000mAh for four flights. IF that were the case I'd consider four flights being safe and five (2500mAh out of an advertised 3000mAh pack) pushing your luck.
One plane I have 30cc with ignition and 6 brushless digitals, consumes about 250mAh per 12 minutes of airtime, at worst your's might consume 500mAh per 15 minutes??
