#2 nodemcu is poor choice for 8266
The nodeMCU board is not a good choice for the console port. It has a built in usb to serial controller that is on the same wires as the rc2014 console. This causes problems with the digital data levels.
The better choice is the Adafruit HAZZAH. The serial lines are not connected to anything unless you
plug in a usb to serial device.
Experiments with the HAZZAH shows much better performance, but still seeing the data loss problems.
