Hi all! Sorry If my english is not good...
I am new to APM, I'm using an Arduflyer kit (board + Lea 6h GPS + RadioLink). The board is 2.5.2. I tested the kit (with internal compass) and works fine for now with GPS 3d Lock
In some videos I watched, it's recomended to cut the trace on the board to habilitate the external compass. And about the radios, the firmware can be updated with a Ftdi cable. So i would like to know 2 things:
-Is it really better to use the external compass that comes with the GPS? I will use the autopilot on a Skywalker plane, so there will only be 1 motor and Esc (less interference than a multi), and I am not sure to cut the trace, because right now it works fine.
-Do I have to update the Radio Firmware? They are working too, the version is 1.7.
I will appreciate your opinions!
