It's very difficult for me to describe the handling and feel of flight ... I apologize but I am not a professional ... All I can say is they are both extraordinary
... For EC135, it's very bright and easy to handle, pleasant to drive in the mountains with a very good power! ... For the A109, I find it very "accurate", he responds really well to control and it's very easy to land safely ... It also has a very good cruising speed and he has an ease of acceleration quite incredible ... and the cockpit is fantastic!
Again forgive me for my English ...
What I regret in your models (it's a detail), but it would be really nice to add a pilot. Maybe it already planned?
I will soon buy the BX430, it's REALLY beautiful! I hope I'll enjoy the ride!
I also think making a new video with almost all helicopters that can be found in x-plane.
