When I arm my copter the motors spin up straight away. PX4 with Arducopter 3.1-rc7 and 20A hobbyking ESCs.
I have done my ESC calibration and RC calibration, my flight mode is Stabilize. When I do the ESC calibration zero throttle is zero throttle but then I arm and the motors spin up on what was calibrated to be zero throttle.
I have been looking into parameters like THR_MIN and TRIM_THROTTLE to see if they make a difference but to no avail.
Any help would be much appreciated. Cheers!

I have found a parameter called MOT_SPIN_ARMED and set it to zero.
I helps but I still have the motors spinning up unless I hold the throttle down (literally). I hooked up an oscilloscope to the output and the signal was jumping around at low throttle levels.
Any ideas? Is it a bug in the firmware? Cheers
