"Nice work, very informative.
Am I to assume that setup is done with a linear pitch curve in the TX, which does not change for flight, as the pitch can be limited in the software? Also, would you recommend levelling the swash mechanically before…"

"Rob,
Just wondering if you got a link to your Set-up Video?   It has been awhile since I looked at my Trad Heli with APM and am considering switching over to PixHawk, PHL(PixHawk Lite) to be more precise, on my 600, which currently has an APM on it…"

"See page 283 of this thread for further discussion on this issue...I don't think that it ever got resolved."

"Phil,
I always get a similar problem...too many %% signs.  I believe that it is a bug in the firmware (one which I wish they would correct).  My "fix" is to simply switch between OSD screens using channel 6 or 7, as set up in the MinimOSD OSD…"

"Impressive. I have similar results on my RCTimer Trooper X8 and a FixHawk controller which is also just attached via 3M 4011 Double Sided Tape."

"Ya, I know :)  BTW, this is with APM 2.5 hardware and not PixHawk

I'm just trying to make the point that 3.2.1 must be more sensitive to vibrations as 3.1.5 was able to handle the same frame fine in AtlHld and Loiter modes, as mentioned several…"

"My most recent logs from the same frame mentioned in the post linked above...have tried several different methods to reduce vibes, including different props and mounting methods...All flights are with most recent firmware 3.2.1 and all flights…"

"I reported a similar occurrence with motor pulsation which I mentioned back on September 5th in the ArduCopter 3.2 beta testing thread (http://diydrones.com/forum/topics/arducopter-3-2-beta-testing?comme...).  Thought that I had the problem solved,…"

"Randy,
I believe that I have solved the problem.  Mounted the APM on Zeal Gel and nylon tie (covered in fuel tubing) strapped it down.  Just finished re-testing in post Hurricane Gonzalo winds (41 gusting 53 km/h) and quad held really well in both…"

"Randy,
Thanks for the feedback :) I just wanted to make sure that it had nothing to do with the motor "pulsing" fix that you implemented a few rc's back, as this is the same frame that was encountering that problem.  I will focus on reducing vibes…"

"Randy,
Mentioned this a few posts back that I was seeing un-requested throttle out commands causing rapid assent of quad with following specs:
APM 2.5 (now using external mag/GPS)
SunnySky 4110S-25 340KV motors
HK Multistar 45amp ESC running SimonK…"

"Rainer,

Thanks for the reply. I will readjust the values for STB_PIT and RLL; BTW, these numbers were derived from autotune and were initially even higher (closer to 10 if I recall correctly). Would such high values caused the problem that I…"

"Randy,
Another Log from 3.2 rc12 on Tarot 650 quad with following specs:
                                              
APM 2.5 (no external mag)
SunnySky 4110S-25 340KV motors
HK Multistar 45amp ESC running SimonK firmware
Props - 16x5.5 CF…"

"Auto tune and then lowered them further."
