Thanks in advance for any help. Pixhawk PX4, Arducopter 345 helicopter, 500 helicopter. Problem is Pixhawk is double flashing yellow led (error code will not arm) there is no error message in Mission Planner hud screen, in failsafe screen Stablize is showing in red color, radio and accel and compass are calibrated. Preflight checks disabled in full parameter list. Any process to find what is causing no arm and yellow led?
Thanks
