Hi Akmatov,
Congratulations on the new Beaver. Sad to say the yoke of the Aerosoft Beaver is not removable. If you can move your perspective, you can look around it. I use TrackIR, and it works pretty good. But at $150 US, it's not everyone's first choice. I could not stand to fly without my trackIR system. (and Voice Attack too). If you're flying on autopilot, or sitting on the ground, you can push or pull the yoke out of the way to see past it too.
As for the wheel chocks, they come out (if equipped) when the parking brake is applied. Check your flight sim's key bindings for the parking brakes. On my system that is Ctrl+. , but I use voice attack to activate mine. I say "parking brake", and they apply or release. I am not sure if that key combo is default, or if I changed it. I don't remember. I use the amphib version, which only has a pitot tube cover, no chocks or tie-downs.
I use three monitors, and AMD Eyefinity 3x1 configuration. I've not had that issue pop up on mine, but I neither use the kneeboard or the GTN 750. Sorry to be no help on that.
