Jim Dowdle replied to DG's discussion INAVerr- Is it the GPS or FC or neither?
"Very gppd!
I just check for M8N firmware update.  There is none yet available.
Do you know of a way to set Arducopter to interface the GPS at a higher baud rate?
How about update rate?
I just checked for GPS parameters.  There is a GPS_type1 and 2. …"

Jim Dowdle replied to DG's discussion INAVerr- Is it the GPS or FC or neither?
"OK, well I looked in the .log I have available from my crash, and INAVErr was straightline 0.0.  That may have been, Im pretty sure it was before I upgraded to a M8N.

I just looked for inaverr, and could not find it in either log.
Could you advise me on how to locate it, and I will let you know the results.
I have numerous Ardupilots…"

"I have had a lot of problems with usb cables working.  I find that the longer cables are problematic.  I have found that some of my short cables work reliably.  This was very confusing at first.  All it is I think is the current being pulled by the…"

"I recently had a problem where a quad would not complete all waypoints.  It would start drifting off, and seemed to drop altitude.  It would always do it on the same turn.
It reminds me of your twitchy description.

I cured it.  I switched from the…"

"Is your satellite count good?  I had one copter where the satcount would go to 0 for half a sec or so.  The copter would fly away.  I got rid of that gps to cure the problem, and have started using Neo M8N.  Now I get 16-20 sats and constant…"

Jim Dowdle replied to Phanivyas's discussion Quad just fell out of the sky during mid flight
"Since you have no replies so far, I will see if I can help.  There is undoubtedly better advice available, but I dont see it replying yet.
I have been using ardupilot about 8-10 months.  I have tuned 2 helis, 2 airplanes, and 2 quads.  On the helis…"

I have just started using rtfhawk/arducopter on quads. Tried acro, works. Im using mode1, which does autolevel, but does not limit angle. A couple of times now, I try a flip (which works normally often), and it will keep flipping even after control…
