I used the Search function and did not find this topic. In the newest version 3.2 of the Assistant software, there is a tab I never noticed before. It's under Basic and called "Mounting" and has several drawings associated with it. It talks about "Balance the multi-rotor as you would normally, with the center of gravity (C.G.) directly on the center plate." I have no idea what they are talking about. Is this something new? Did I download the wrong version? Sorry, I'm just not technically inclined but I haven't had any problem flying my Plus!
