I have some problems... First - The repulsive force from the fairings of the two parts is -200 or -100. Correct it, since I do not separate parts obtikateley, as a result the main unit remains inside it. 2: It is very difficult to find a mouse that area, which you can click that would drag the part. 3: Sometimes, when you click on that same zone and dragging it, I pereaskivayu also the inner content of the fairing.
