Navio2 with latest UAVcast build (4.x) and Arducopter 4.0.3. all works well but I cant add a 2nd GPS because on the UAVcast option for flight controller on the launching options it only has ttyACM0 even if my 2nd GPS is attached with USB/TTL adapter.....that wont work, UAVcast needs to actually add ttyUSB0 instead....i know this because it works with Navio2 w/o UAVcast, but the problem is UAVcast takes over the /etc/default/arducopter config file so cant change manually....
