Here's the FLYSKY thread.
GT3B Hack Question and Answer Thread

Did you Calibrate the units?
Calibrate menu:
===============
- enter it by wheel right-turn and ENTER-long
- 6 menu items starts to blink (+ 2 arrows if CH3 is potentiometer)
- use END or ROTATE to change channels
- there is also channel 3 representing CH3 button (for those who will do
some 3-position switch/potentiometer modification)
> There is 1K resistor connected between CH3 button and +5V, so
simply connecting linear potentiometer instead of CH3 button
will not work. Usefull results can be done with logarithmic
potentiometer 10K which has 1K at half of turn. Or eliminate
internal resistor to +5V, connect potentiometer between +5V
and GND and potentiometer output instead of CH3 button.
- there is also channal 4 representing battery voltage
- calibrate as usual (for channel 1/2 left+mid+right and ENTER)
> calibrated value will disappear from menu
> it is not needed to calibrate all values
- calibrate CH3 potentiometer (if selected at global config)
> only left + right positions
- calibrate battery (it will not be probably needed to use this)
> select channel 4
> press ENTER
> set your current battery voltage (measure it by voltmeter)
> press ENTER to save it or END to no-save
- press BACK-long or ENTER-long to end calibrate menu and save values
