battery discharge
Does a transmitter battery discharge faster when in use (constantly moving the sticks) than when just sitting with the switch on? In other words, can I time the time it takes to go from full charge to 9.4 volts simply by turning the transmitter on or would that give me a false reading from what it would be if I were flying?

The battery usage will be the same.

I just wonder if you ever checked that and know it by personal experience.

RE: battery discharge
I must admit that I have never checked this with an ammeter. But I am a bit of an electronic expert (amateur radio - "ham" - extra level). The transmitter uses most of the battery to drive the power out of the antenna. Moving the sticks drives a potentiometer which changes the pulse width of the pulses sent by the transmitter. But the energy required is the same no matter what the pulse widths.
