After start and before taxing to the runaway, as I open the throttles I get the beep beep sound, I have checked everything, but something is missing please help with any ideas.gasok

Hi Gasok,You're moving the throttles into the takeoff range and triggering the takeoff config warning (the plane is not configured for TO).Make sure the parking brake is off, flaps are in the takeoff position, trim is in the TO range, and go easy on the throttles.Take care,Bryan

Thanks, I try that this evening and get back to you.
