I hope not as well. as long as you didn't have you gyro plugged in I'm sure you're in good shape. if your gyro was plugged in, I'll say a prayer for it I'm sure it's imperative to use a 7.4 V LiPo to your Align and a a step-down Voltage regulator to your 401 gyro. This being said your rudder servo will be working on 4.8 volts and not give you the optimum results for holding the tail steady. I wouldn't worry about it until I tried it. (hover) OR maybe someone else reading the threads can intervein for more direction. The futuba rudder servo that preforms well on 4.8V is about $40 more than the Align servo you have and would be an option if the rudder doesn't hold well.
