yes, it seems as if everything in this sim has limited functionality at the moment.
I have tried to make a trainingflightmission with the editor. It works but when you are in the cockpit (BF109) and try to begin with startup procedures, the plane starts to turn and tilt slightly to the left and nothing can stop it, no brakes, no locked tailwheel (wonder if it works at all?).
Apart from that, you cant get the engin running. You set the magnets, turn them on, set your mixture open radiators, put proppitch low and start ignition.
The propeller makes half a turn, you see some little clouds from the engine and thats it, out, no engin startup.
When you fly a given mission its the same, a few minutes flying and your cockpit is full of oil.
Maybe I do something wrong but if the sim is so "reailstic" this time, they should have better tutorials in the manual for such things.
That including the many bugs the sim still has, makes it impossible at the moment to fly and have fun. Hope a coming patch will make things better but for now I just leave it aside.
By the way, thats not my first flightsim, until this one came out, I was flying IL2 from the beginning 10 years ago, (also on full real settings).
