it's not about screen or 3d view, it's about attitude, it s so hard to keep the attitude still ! I videopilot UAV helicopters with LCD goggles in real life and it's not that unstable , and we're just talking about small models with a Wind/Weight ratio a lot higher of real scale helis, the can move like little mosquitos If I givve they the right inputs, but they are still if I don,'t they mantain attitude if i don't move my fingers..., I suppose (but I can be wrong offcourse) that such a big heli like the KA50 shouldnt be so unstable.
