With a traditional R/C system, not on 2.4 GHz, and without a regulator between the Rx battery and the Rx, normal behavior would be for the system to stabilize as the peak charge of the battery was consumed while the voltage was dropping to the nominal range. Of course, using LiPo cells in place of traditional Nicads could aggravate this problem as well. While receivers are more sensitive and servos move faster with more voltage, the receiver also becomes more easily bothered by spurious signals in the aether and the servos are enabled to track these spurious signals more accurately. This is one reason that I don't mess with 5-cell receiver packs. Yeah, I'm an old fart with old ideas when it comes to electronics. If you're running PCM, forget all that I have said previously.
