Yes I'll bet that was your problem! [:@] Easy mistake to make for a newbee. The electrics are very sensitive to changes in voltage. When you get about halfway through a battery pack and the voltage has started to drop, if you crank on the throttle the gyro will sometimes get out of sync for a bit (you'll see the gyro light turn red) till the electrical load stabilizes and the signal smooths out (gyro green again).
