Hi,I have bought a Hexa from 3DR and had huge problems tuning ALT_Hold in 2.81. So I´d decided to do further tests on the actual master branch.Compiling with the special Arduino 1.03 runs well but,…Continue

"The same in arduplane 3.0.3 ... I have a flying wing.Servos is connected to buddybox output, one of buddybox inputs reads APM outputs, another (master) reads receiver outputs. This setup is REAL manual and failsafe from anything can happen in APM…"

"I had D to 0.01 and it works better (fewer corrections). It should get much easier to setup with autotune for yaw https://github.com/diydrones/ardupilot/issues/874."

"As you can read 3.1.2 has an critical bug (#1) which costs me many hours of analysis and hundreds of euros. But I am no expert. The motor out is missing in your logs."

gregmaan replied to MHA's discussion APM 3.1-rc4 yaw PID tuning
"Same problem for me, but with Rate Yaw D = 0,0100 and enough IMAX its nearly good. At the beginning of anouncing AC 3.2 there are some posts from developers that they would add Yaw tuning to Auto tune for 3.2. But in between there is nothing in 3.2…"

"Here you find instructions: http://copter.ardupilot.com/wiki/common-ublox-gps/ I did not have these problems. Maybe your GPS is defective? But it looks for me like communication error between the board and the GPS."

"I am really no expert but I will see the same as you: GPS glitches and GPS errors. I would think to check your cable to the GPS and maybe the configuration file for the GPS if its no original 3DR Modul."

gregmaan replied to xoltri's discussion Pixhawk causing motor sync issues.
"The 3DRs are Atmel based, and they don´t have all NFET. From the pictures they should be DYS 30A, but I can´t get them work with this SimonK configuration (LFuse/HFuse Problem). I am also looking for better ESCs with all NFET and…"

gregmaan replied to xoltri's discussion Pixhawk causing motor sync issues.
"I also changed back to my old 3DR 20 A ESCs. They did not have the simonk inside so i flashed them. The copter runs much smother with these ESCs than with the RC Timer 30A Optos. No jerky movements within flight mode changes and Nav point changes.…"

"I had the same issue with the pixhawk since february... I think your problem is related to the Stability Patch fixed in 3.13 and no sync issues with simonk 2014/03/06. I have no more sync issues with the new simonk fw and 900kv motors on 3S. My…"

gregmaan replied to xoltri's discussion Pixhawk causing motor sync issues.
"I tested yesterday on the bench:The WiiESC firmware does not produce any vibrations while desyncing, But the rpm of the motor are not stable at certain PWM values with my ESCs. With the simonk from 03/06/14, I could not see any problems on the…"

gregmaan replied to xoltri's discussion Pixhawk causing motor sync issues.
"Nice work, Thanks ! I will also try my RCTimer 30A opto with WII ESC.But I am not sure if the vibrations get worse if the ESCs recover from desync.Maybe the actual simonk also works with my 900kv motors. Will do some tests at the weekend."

"You should read in wiki how to make the compassmot, and the are no current measures while doing it (0). But I don´t know if this solves your issue. Voltage measuring maybe wrong too, because it goes below your Batt_Failsave of 10.5 V and your…"

gregmaan replied to xoltri's discussion Pixhawk causing motor sync issues.
"Hi Peter, maybe do you have a link e.g. to your esc32? I have still the same issues with 3.1.3 RC1 with RCTimer Opto 30A SimonK and TMotor 2216 with 900kv. With reducing RC_Speed to 200 the issue was gone but that should be no good solution."
