His test circuit uses six 2N2222 transistors to protect the Arduino from excessive current ... this is an impractical way to use a brushless motor. But it is a wonderful way to learn about ...

So he decided to change the radio over to work on the 6 ... radio circuits are tuned to pretty close tolerances and going from 27 MHz to 50 MHz seemed like quite a leap. The answer? An Arduino ...
