Flash4 Voltage Calibration

Some Hitec transmitters have poorly calibrated voltage display and/or low voltage warning. Both of my radios were reading high on their voltage display, giving an overly optimistic view of battery state. There is a separate adjustment trimpot on the circuit board for Display Voltage (upper trimpot) and Low Voltage alarm (lower trimpot). You need a thin flat-bladed screwdriver to adjust these trimpots.
