 |2/17/2020|My brother says that the A4 can do 420 degrees per second rotation around its longitudinal axis. A small amount of rudder is needed, but only a tiny amount. I suggested 1/8 inch. He also says that the plane is quite stable holding straight and level flight. But it is quite sensitive on the controls.|
 |2/17/2020|As-of this writing, having problems where the Arduino Mega 2560 with LCD display keeps becoming disconnected from I2C bus. Realized that I had been feeding in only 5V (the output of the Raspberry Pi) into the Vin. It is expecting 6 - 20 volts there, and there is a diode and other components which reduce the voltage, probably causing the problem|
+|2/17/2020|Ran Mega on its on 12V supply. Still having I2C bus issues. Want to try turning off the LCD display and just blinking the LED with input, to see if the LCD display connections are causing the problem|
