The problem is you,and not the aircraft.
If you start from cold and dark,once the engines are runnig,you have to get the electrics online,before the radios will respond to ATC,read the manual,and get to know the aircraft and its systems,once mastered,you will find the aircraft is superb,and only has a few minor faults,but be warned,do not let her stall,as you will find it next to imposible to recover from it.
