Control loop frequency

Hardware Pixhawk 2

Hi all,

The default control loop for Arducopter on Pixhawk1 is 480Hz.
What is the default contol loop for PH2?

Thanks: Tom

Should be the same because of the same MCU

OK, so standard control loop is 480Hz by default.
What is the max?
Can it be set to say 4kHz? That would match the 250us OneShot125 refresh rate.
