Yesterday I did a first fly on a rebuild from a battery failure crash. After the crash, I bought a cycling charger [Accu Cycle] and installed a new 1,400 MIL amp battery in the plane. Friday night I discharged both the transmitter battery and the receiver battery and gave them a full charge [ 15 hours at 125 for the 1,400 and 50 for the 700] per instructions with the new charger, [I had previously cycled both batteries 3 times and found the 1,400 Mil amp to take a charge well over 1,300 mil amp and the 700 mil amp transmitter was well above an 80% chg.] Well, I flew for no more than 40 or 50 minutes total on air time and the receiver battery was down to 4.6 volts. When cycling, it took 6 hours to go from full chg to the 1.05 recharge level, this should have given me at least 2 hours of flying as I calculate. The only thing I can think of is that the amp draw on this old equipment must be higher than 125mil amp. How would I test for the amp draw for the servos and receiver?
