My 9C draws about 280ma.
My servos (JR) draw about 10ma at idle but can draw as much as an amp under full load.
There really isn't a set value. You can map your draw over time and get an idea of your average for your flying style.

I'm looking for "approx" curent draw of both a computer type Tx, and a 4 channel RX.
I know this will vary from Tx make and how it's used, as is true for the Rx, however, I would like to closely emulate the discharge rate for both when I cycle the batteries. I'm using 400 Mah for the Rx and 500 Mah for the Tx. Does this sound close?
