I just recently read a warning on forum to press the reset button after plugging in the lipo on APM 2, in order to avoid the 'reverse compass' bug. Does pressing reset return all settings to default including new PID tuning writings? What about TX calibrations and leveling? What exactly does pressing reset do, besides avoid the 'reverse compass' bug. Sorry if these questions sound dumb, since I am very new to UAV.
The reset button is like just plugging in the battery. It does not reset any of your calibrations or settings.
Does this procedure eliminate the "reverse compass" bug?
It suppose to. However, I've never experienced the bug myself.
The 'reset' button on an ATmega is like the reset button on your computer. It forces a restart of the CPU. It doesn't wipe the flash/eeprom.
Just now, my copter experienced a failure. First, it tried to pitch backwards and yaw to the left. I noticed that the back motors slowed down significantly, then stopped. When I tried to manually compensate with stick it did not respond, then it flipped over. I pulled the throttle stick all the way down to shut off the motors but it did not respond. Does this sound like the flip bug on APM 2? Have you experienced anything like this. I haven't opted out the high possibility that it was a mistake on my part somehow (perhaps I accidentally put it into loiter mode somehow). Anyway, nothing really bad happened except I broke one prop. Is it possible to pull the incident up on a recorded log on APM Planner? If so, can someone tell me how? Thanks.
