I've recently been playing with a Naza-M. There's a little board out that allows you to use MinimOSD and/or a pair of 3DR modems with the Naza called FBOSD. Here's a link to Jay's website: http://firebug24k.com/index.php.When using the modems there…

Jim Mullen replied to Clinton Mills's discussion Copter Propellers Rotation (Incorrect)
The APM can not control the direction of the motors. If any of them are turning the wrong way for the arm they are installed on you have to switch any two of the three wires going from the ESC to the motor. This will reverse it's direction.…"
