Philipp Stenzel commented on leonardthall's blog post ACRO for ArduPilot 3.1
"Issue:
Switching from Acro to Stabilize or Alt Hold makes the copter yaw a little bit.
All the rest couldn´t be any better! As discussed in a forum thread I removed any dampening material between APM and the bottom plate of the Discovery. Just…"

"Did the upgrade but at the same time switched my stock DJI F450 to TBS Discovery so it is hard to compare.
It´s the first time that I have different PIDs on roll and pitch, the quad needs P term around 1,2 on roll and over 1,5 on pitch even though…"

"Hi Leonard!
This version is no longer labelled as "3.0.1rc1ACRO" but simply "3.0.1", correct?
Means it is official release 3.0.1 plus pure acro capabilities without the need of toggling any switches so far? Just install and go ahead upside down?"

"But why doesn´t  ACRO need almost any I term at all (and is unsensitive to value changes) whilst standard 3.0.1 loses that much of stability with same settings?"

"Installed 3.0.1 yesterday to get a picture of its GPS improvements (marginal in terms of FPV flying). Did not take the time to change PIDs, just flew around a bit. I don´t know if it is because of my low I terms, but 3.0.1 is A LOT less stable when…"

"Will rc2 include Pure Acro option? In other words, is Pure Acro version intended for rc2?"

"Dummy I term? Did you find a way users do not need to adjust it any more?
I tried with my MultiWii Quad yesterday (Alex Khoroshko says that PID Loops are pretty similar to ArduCopter now) and definitely reduced I term there a lot as well. But I…"

"Changed my mind and tried different I term settings this afternoon. Modified in flight via Ch6 knob from zero to 0,2. Funny thing, there isn´t almost any difference at all! Even with zero fast forward flight is without the slightest tendency to…"

"HAK, stop wobble (higher frequencies, similar to wobble on fast stick centering) to me is caused by too low Rate D term, try to increase!It´s a bit strange, my Rate D is three times higer than default at the same time Rate I being around an eighth…"

"Installed latest Acro mod, reset all loiter parameters to V3 defaults and it worked not bad, but copter starts wandering on yaw input. Set all compassmot values back to zero and it got better! Adjusted declination manually, will recalibrate ACCs and…"

"Reset all loiter parameters to 3.0.1 defaults, Works pretty good now, holds position, but started wandering after yaw input. Since red line in Mission Planners Flight data always fits perfectly copter´s heading even when climbing at full throttle I…"

"I will test for sure!
Is there any need to set I term higher than necessary? I mean rc1 worked perfectly with 0,015, and I tried 2.9.1b with the same rate PID values as V3 and there was no pitch up at all."

"Did compassmot and compass recalibration (posted values before, don´t look bad to me) but had almost the same problems again. RTL was better, headed towards home in most cases and stopped pretty close above home position but descent always was far…"

"I did not want to affront you, I definitely see the big job developers do. Im very sorry if it looked like personal attack!
Inertial navigation is a big thing without any doubt but not to everyone! If it needs a lot of setup and expensive hardware…"

"Leonard, I do not think your modification converted ArduCopter from reliable working horse into nervous diva. I am pretty sure that it is not a faulty GPS causing my problems after reading V.3 discussion. It is simply the price for precision that…"

Philipp Stenzel commented on leonardthall's blog post ACRO for ArduPilot 3.1
"Just skimmed over V.3 discussion. I must admit that I am not too keen on the inertial navigation stuff. So is there a way to combine 2.9.1b with Pure Acro modification or in other words is it possible to turn of inertial navigation completely to get…"
