Yeah, what many don't understand (keeping in mind that this IS a beginners forum) is that the more you move the sticks, the more the servos work, and the more of a drain there is on the battery pack.
Often, pilots will try to correct for movement that they have no real control over, or with the latency involved, correct for something that has already happened, thus overcorrecting.
What I learned way back when, during my training, in fact, was my instructor told me to leave the sticks alone during a straight and level pass. I did and watched the plane. I realized that it moved the same way no matter what I did. So, I tend to leave my sticks alone, don't overcorrect, in other words, when I don't need to do anything but fly and watch.
You said it, TimBle
don;t constantly fly on the controls, thats why planes have wings....
