RF remote via SPI

Hi Sean,

I'm looking at the latest controller schematics:

  https://pypilot.org/schematics/wp_controller.pdf
  https://pypilot.org/schematics/highpower_controller.pdf

Both show the 5V atmega328 has an 8Mhz crystal.

(The hat arduino also has an 8Mhz crystal, but it's running at 3.3v)

Is 8MHz the right crystal for the motor controller?  If so, could the motor controller be run at 3.3V?
