Hi, guys. I've just bought a APM 2.6 and loaded 3.2.1 firmware, quad x.
I tried to use Dave C''s PID tuning method. But encountered two problems.
first,I can't seem to set rate PIDs to zero, Is there a min limit on the PIDs? why?
Also, I can't save the MAX and MIN value on Channel6 tuning. I input the values, they turn green; and I "Write", then "Refresh", but the MAX and MIN jump to 0.000. The APM was able to keep other setting values though. I tried with "rate P,I,D" and they all have this problem.
After some googling, I realized this could be triggered by Gimble Settings, but the issue remained after I disabled the Gimble completely.
