I've been working on an X8, and it hasn't been going too well. Sigh.
APM 2.5, Arducopter 2.8.1 compiled for:
#define CONFIG_APM_HARDWARE APM_HARDWARE_APM2
#define FRAME_CONFIG OCTA_QUAD_FRAME
#define FRAME_ORIENTATION X_FRAME
Mission Planner 1.2.29
Futaba T8FG, R6208SB and the ArduPPM_v2.3.13_ATMega32U2.hex firmware. Power provided by 2 4S 5500 in parallel feeding the 3DR power module. Avroto 2814-11S motors, APC 12x3.8SF/P on top and 11x4.7SF/P on bottom. BlueSeries 30A escs' running simonk firmware.
Motor test worked just like the example on the wiki, all motors cycled as in the video.
Today, I took it for its' maiden flight. All default settings, except for Channel 6 set to Rate_P at 0.120 . The idea was to turn it down to clear the expected wobbles.
It lifted off fine. Nice and stable, no wobbles, never touched the right stick. At about 10ft, it pitched forward into the grass. One broken arm, and here I am.
Would it be possible for someone to check over the attached logs for a hint on why it pitched into the grass?
TIA,
Rick

Out of curiosity, why are you compiling the code yourself rather than just loading it via the MP? And why are you using 2.8.1 rather than 2.9?
