Rx battery drain question - 5/5/2005 1:30:26 PM

Status: offline 		I am using a Hydramax 1200 mah NiMH rx battery in my Giant Aeromaster. I have cycled the battery and the capacity is fine, but after one 10 minute flight, more than half of the capacity is used up. Is this normal? I have 5 qurter scale servos and 2 standard servos in the plane. I cycled the battery after a 15-20 minute flight the other day and there was only 256 mah left in the battery! I want to know if this is normal or if there could be a bad servo causing the extra drain?
