Some information regarding erratic RPM. I have used a twin screen display for five hours flight time with stable RPM readings. Suddenly one screen shows erratic rpm readings from boot up. The second screen is ok. After a few minutes I rebooted the screen showing erratic values and it immediately gives good stable readings agreeing with the other screen. One hours flight and no sign of a repeat.
The erratic values appeared to be caused by the display jumping between two values, one correct and one higher incorrect value. Typically the values were c1200rpm (correct) and c1800rpm (incorrect)
