Ok, I see.... yesterday I set up my t-rex but I missed checking 'ccpm interaction' because I didn't understand what it was..... next thing, I went to fly the helicopter and as soon as I was trying to lift it, it started to go left and backwards against the wind direction.... do you think that had anything to do with it?????? It was not stable at all.... I had to push to the opposite sides to keep it balaced but it was a bit windy and I could't keep it straight and I tried to land it and it was going too much to the left that it turned on the ground.... could that have been caused by the 'ccpm interaction'??????
