"Ok, just one thing to confirm: now I'm working based on the libraries in ver 3.2.1, in that case, for APM2, the AP_InertialNav library, or more precisely, the "AP_InertialNav.cpp" is actually used by ArduCopter to…"

"OK, thanks. I fully understand the intent of the example. However, that will make my attempt to build my own flight controller from the libraries trickier! Actually I'm trying to build a controller similar to Dr Gareth Owen's (Android…"

"Hmm.. looks like you're using the example sketch.  Perhaps it's missing some information or parameters (like accel calibratoin parameter) that make it not work.  I think that example sketch was only there to ensure the libraries…"

"Hi, I'm having exactly the same problem currently. I also noticed that this example has been removed in the latest releases, which are intended for pixhawk only. However, I think this is still a very necessary example for APM2 users. Is there…"

"Hi;   Also for Y6 config - should I just change the line '//#define FRAME_CONFIG QUAD_FRAME' in the APM_config.h file to : #define FRAME_CONFIG Y6_FRAME ?   Or do I also need to do something else before compiling?"
