I have a question that I have not been able to find an answer to. As the voltage drops on your receiver battery, does your effective range of flight decrease? I've always assumed that if I have enough voltage to operate the servos, then there is enough voltage for the receiver to operate effectively (i.e. as long as I can still see the airplane the receiver is within range of the transmitter). I would like to know if that is a good assumption. Any help on this subject would be greatly appreciated and the more detailed the explanation the better.

Thanks,
Gary

p.s. How about the effectiveness of the transmitter as its voltage decreases?
