wrong!! you will fry your reciver if you use that pack. If the pack is rated at 7.2 volts that means it putting out about 8.2 to 8v which will burn your reciver up. the reason your saying that most reciver are rated at 7.2 is because a 6v pack puts out that kinf of voltage
Whether or not it will burn it up..... it is a definite possibility. Do like flyingjibus said earlier and remove a cell. The 5 cells absolutely give you what you need. The voltage will be = to the standard 4 alkalines. I have seen servos with higher ratings than norm but the RX would have to be specifically designed for such and would come with accompanying information...
