Hi, I took my quad outside for the first time yesterday and I'm experiencing a few issues with the loiter mode.
a) the altitude hold component is fairly inaccurate - at an altitude of cca. 10m I get a deviation of about 5m each way and after a while the quad starts a slow (0.5m/sec) descent which only stops when I manually override it.
b) the position hold is even worse. The copter will start traveling in random directions (not just correcting for a meter or three of drift, again leading to a manual override.
Any suggestions as to what I should be looking at?
Thanks,
Hans

I think I have same sort of issue, though I managed to get alt hold to be fairly accurate with PID tuning, but loiter is just zooming random direction at large angle. What is suprising is that RTL seems to work fairly well (atleast while I tested it while holding from the top).
The loiter behaviour can be seen at the end of the attached log, theres a test with both RTL and loiter.
Firmware is the 2.0.38 release version.
