"+1 Eric (actually it deserves more than +1) Kevin you do find some really important issues and let us all be happy about that. Finding an error is in my world just as important as writing new code, but remember that the person who wrote the code (or…"

"Hi Markus, If you have the log files please post them so the developers have a better chance to hunt such a relatively rare error Thanks /Benny"

"Hi Albertino, No unfortunately not. Note it was on 2.8.1 I had the error. In Randy's post above he only looks on the baro spike, but the problem started before. You can see that the copter is not doing a sharp 90 deg right turn as it should,…"

"It sounds a lot like something that I have had. (ok auto mission and then next one that just goes bats...) Thou I had no problem with baro reading. Just yaw change and "random crash mode initated!""

"Hi Benny Experienced the exact same thing a few days ago whilst flying a mission. After checking the logs and google earth files i saw a massive spike in the baro readings just when the quad fell out of the sky. Randy is assisting me with this but…"

"Hmm no attached file. I try again: "

"Ok not taking acc out of the loop, but use them as in 2.8.1 and not as they will be used in 2.9.2 /Benny"

"but remember a lot of us normally fly without telemetry. Why not just let the SW judge if vibration is acceptable for Z (later also X and Y) inav or the vibration is so bad that it should use the "old" but ok 2.8.1 approach. The user will…"

"+1 Stephen. I think that feature might be able to save a copter or two e.g. if the frame goes in resonance. It will also be easy for the user to judge if the vibration level is ok (you will have a flag in the log that will tell when and if the…"

"I know the over water problem, but if we have a battery failsafe I guess we will only have very limited time left and then gaining altitude seems wrong. If we "just" have a throttle failsafe situation I will agree that a Ch7 option could…"

"I don't know enough of the log and SW yet so Im guessing a bit here, but we have high roll and pitch in. I think we can make adjustment in RTL. Thats great when we have the copter in RTL and it's on it's way to hit a big tree on the…"

"Kevin, RTL is not configured if you check flight modes. RTL is invoked because of throttle failsafe. The second failsafe at 7625 is because of battery failsafe (as a note to developers should battery failsafe not trig a LAND instead of RTL?). /Benny"

"William, The odd chart is because log data is a 16bit signed value so when the error is above 32767 it will wrap around to -32768. The copter just gets further away from home. /Benny"

"Leonardt, Yes the copter have flown from 2.7.3 (unfortunately not with the same props ;-) I have used standard PID until now. I have tried 20hz filter on the MPU6000, but still with oscillations. The resulting motor output in altitude hold and…"

"SAA, I have DX8 and AR8000. I use 11mS DSMX. Gear is used as mode input. I have not updated the PWM to PPM converter SW. I have not seen the throttle problem. /Benny "

""Interesting" Z axis oscillation. I have just mounted my APM 2.5 in the protective casing. Unfortunately I was only able to order the top entry type at the time I bought my APM's so because of the cabling I have almost no room for…"
