I was at the field Sunday when a young kid came over and ask me a question. Long store short he has a carbon core 650mm qaud program in his Taranis. And he is wonder if he changed the quad to hex and then selected 3 of the 6 positions switches on his pixhawk would it work? The reason he ask me this question is because he saw me with my Pixhawk at the fiekd some time back. And he thought I had it all figured out lolololol. I told him I would ask the guys here on the forum because they know more than myself. And I felt sorry for the kid because he got just as many answers at the field as I did a big fat "0". The ideal does seem like it might work but you would be loosing some of the Pixhawk features.
