The Sea King is one of my all-time favorite helicopters and I thoroughly enjoyed flying this model in XP 10. Unfortunately, it needs updating for XP 11 and soon the latest release. The primary issue seems to be that GPS issue older models had. I tried tweaking it myself, and it at least runs, but I continue to get rotor shadows that are pitch black and extend to infinity. That makes the model virtually unusable. (Which, I guess, might be always true because it is a virtual helicopter, but you know what I mean.) I fly in VR through FlyInside with Oculus Rift and LeapMotion sensor, so having fully interactive cockpit is also important. I'm hoping the developer will update the model.
