Re: V2.2 - ACRO PID implementation is wrong, right?

You are right, Alex, no way to toggle between soft leveling and pure acro at the moment but to adjust level speed by modifying ACRO_BAL directly or by the slider you mentioned. The guys seem to work on the implementation of additional flight modes similar to MW´s Acro ("Pure Acro") and Hor...

Re: V2.2 - ACRO PID implementation is wrong, right?

I didn't like the inability to turn on or off this soft self-level feature. This is possible, with ArduCopter and MegapirateNG as well. It´s not too obvious, just set ACRO_BAL and ACRO_TRAINER to zero, that´s it. Until latest Ardu mod it was still not possible to flip but any selfleveling was deact...

Re: V2.2 - ACRO PID implementation is wrong, right?

1: I think removing a few parameters from "tune before flying" list is a good thing. 2: Actually, the ordinary ACRO is made this way in ardupilot. 3: Also, this 'memory effect' issue is strange. I: Agree, I like this concept of a central control loop, which gets input either directly from...

Re: V2.2 - ACRO PID implementation is wrong, right?

I cannot reproduce your yawbug, Noc. But: I use switches to start and stop motors so when arming my props don´t start spinning immediately as they probably do without the use of a throttle hold function. I think it could be possible that the arming procedure at the same time includes a little bit of...

Re: V2.2 - ACRO PID implementation is wrong, right?

I installed this and replaced line 111 in IMU by seven lines as proposed by Plüschi to prevent MPU6050 and ITG3200 sensored boards from loosing orientation when switched to selflevelling modes immediately after flying some flips in a row. On my stock Gaui 500X with Crius AIOP V2.0 this works perfect...

Re: V2.2 - ACRO PID implementation is wrong, right?

Wobbling occurred reproducibly from hovering just by flipping cyclic stick close to its limit being far from full hrottle.

Response on roll and pitch is not the issue. yaw is. With MultiWii roll and pitch always feels kind of flying in gusty winds although conditions are perfectly calm.
