Hello, I am having an odd issue with my omni-x rover. Not all motors are turning on as they should be. When moving laterally, all 4 motors are active, and moving properly, but when moving forwards/backwards only motors 1 and 2 move, and when turning only motors 3 and 4 move. Any ideas why this might be the case?
I am attaching a log file with this behavior, if any one could help diagnose the issue.

Hi guys
Please forgive my english. I will do my best to make myself clear
I build a trex 450 pro for test and tryout purpose before my dominador 550L
Parts:
Trex 450 pro DFC
Pixracer flight stack. 3.6.9 Heli (tryed legacy too)
Hobbywing Platinum 40A v3 ESC
KST 215 Metal coreless digital servo V3.0
Mavpixel MwOSD SiK etc
Pixflow 1.3 Disable
GPS uBlox 8Well, the odd behavior start when the flight controler is armed and throtle is above 1776 PWM
The swash tilts backwards “elevator” and left “aileron” slowly then it jams in that position and don’t respond to Stick moviments. Then I bring throtle down below 1776 pwm swash levels and unlock working normalyI tryed to limit RC3 input to 1776 pwm but no luck at all
The only way to solve the issue is to limit on the radio throttle to 1776 PWM. But it brings me some head speed and colective issues.
This behavior only happens on armed situations
On Stabilized althold acro modes. Do not try othersLooks like some kind of leak in the loop because it slow to the position and stay there
Any help on that?

Hi, I have an intermittent problem on Pixhawk 4 Holybro, the drone gets slow responses and then I make a speed error and for the second time ask for the controls, but testing later it works normally without making any changes. The interesting thing is that my EKF is only enabled when the parameters of “velocity_horiz off” and “pos_horiz_abs off” are “on” after GPS enters 3D and even then after some time.
What I observed in the data of my OSD that my altitude, while the GPS is not in 3D, is 1 meter and when the GPS enters my altitude is 1010 meters, where I live the attitude is + - 1000 meters. Should not my barometer provide my altitude of about 1,000 meters? In earlier versions of Mission Planner I had no problem with EKF, today I’m using the latest version
What do you think ?
thanks

Hello,
Every time I try to click “Fly to” and set the altitude, I get a “No map click position available” error and the copter doesn’t move.
I also get the error of "Error in command [‘sethome’’]: ‘NoneType’ object has no attribute ‘getitem’ when I do “Set Home”.
I tried doing "guided ", the the copter doesn’t do anything.
I suspect there’s something wrong with my installation but I can’t figure out what. I’m using Ubuntu 14.04.4 LTS, Python 2.7.6, and python-wxgtk2.8.
Thank you.

Hi, as I said here: https://github.com/ArduPilot/ardupilot/issues/9057
"Hi, I’m trying to obtain DPTH messages from my pixhawk 4, but I don’t see that messages when I open the saved file (in SD card) by tapping “Review a Log” on Mission Planner.
I had tried Mission Planner from 1.3.63 to 1.3.68 versionsMay you help me please?,
-What version of Mission Planner does the work?
-What version of Ardurover firmware is the correct for that?"I have the following settings:
RNGFND_ORIENT = 25
FRAME_CLASS = 2 (boat)
Ardurover V3.5.1
I’m using an Airmar SS510 (this one works with NMEA0183)
I think that is because my echo sounder is not an Echologger ECT 400 but an Airmar SS510. Do you think so?.
I don’t now what is going on.Thanks for your help.

Hello,
I have now twice smashed two bixler 3’s in autotune with arduplane running on a navio 2. I have learned that it is very necessary to have lots of safety altitude when entering an autopilot mode for the first time.Each time I entered autotune coming from manual mode, the plane would roll over abruptly and nose dive. Each time I panicked and instead of switching back to manual mode I tried to pull up but the response was too slow and the plane smashed!
Why might my plane abruptly roll when entering autotune mode? I am so scared to use ardupilot! My trims are on par and the calibrations sufficient.
What params should I double check? I followed params from forums related to the bixler 3.
Thanks.

Hello all.
Using Pixhawk 1 with latest AP and MP.
Read the wiki and the other questions here, but it seems my airspeed sensor is an oddball- no one ,mentions the 45250 5A1. Is this just another version of the same —DO sensors that seem to be the baseline sensor? Are there less noisy sensors available?
I have large noise spikes in the signal- up to 14 kph after preflight calibration. Move sensor? Tried that.Change location on external I2C strip? Tried that. Maybe isolate sensor with copper tape? What works here? Dare I use it on an auto takeoff? Looks like a stall-spin event to me.

When I try to connect my pixhawk cube 2.1 to QGC via USB it doesn’t connect (a few weeks ago it works properly). Despite this, I can connect it via telemetry. Does anyone knows how to fix this issue?

I want high frequency(around 20Hz) IMU data from pixhawk for my application.
This is all that I have tried
I tried with wireless telemetry radios first but I knew those are not reliable as there is high packet loss.
I tried getting data using Rpi using dronekit library. I increased the baudrate for serial connection to 115200. For message RAW_IMU & SCALED_IMU I changed parameter SR1_RAW_SENS. I tested it with dronekit example create_attribute.py but the frequency seems to be constant at 4Hz no matter what I set SR1_RAW_SENS. I used to set SR1_RAW_SENS using mavproxy & then run my example.
Next thing I tried was downloading dataflash logs by directly connecting to pixhawk using the USB cable as downloading through Mavlink was taking a lot of time. I used QGC to download as in Mission Planner I couldn’t find direct USB download option, only “Download via Mavlink” was available. But still, QGC can’t download most of them as it gives timeout error. The one which downloaded, I used MP to convert .bin to .log. In the log file, I saw that IMU data was being recorded at every 40ms which serves my purpose. But the problem was that the files downloaded have only around 3sec data, not at all useful & most of them are have only 0’s as entry, in fact some .bin files have only 0’s & nothing else. So I’m assuming dataflash logs are not being written properly.
I looked over the net but many of them have a solution like modifying firmware or taking out the SD card & then reading data.
My drone is a third party drone. I can access pixhawk serially or using a USB, but I can’t take out the pixhawk. Also, I can’t put another firmware inside it.
Ardupilot software version is Copter 3.4.6
Please suggest something.

Hi guys!

Battery Change and secound fly, auto mission went 100% fine until landing. Drone starter AutoLanding procedure, touched the ground and after few secound make a prontflip crash (looks like add pitch forword, drone just lean forward and crashed).
Logs looks normally except Lidar logs. When i looked at RFND lod it looks like in mid flight (after abou 15 minutes of flying)Lidar get info that he is on 4 meters (even thou the drone was at 30meters) and he keeps this 4 meters. Drone started autoland, touched the gound and lindar was still saying that it is on 4 meters altitude. After about 8 secound of beeing on the ground, drone just pitched forward… The End…What couse this? Any Ideas? No EKF ERROR warning what so ever
pls help

Hello,
I have a Trex 700 with Pixhawk 2.1 and when I’m flying in Loiter mode the tail is bouncing up and down during forward and backward flight.
Maybe someone know what could be the problem or what parameter need to be change to eliminate it?
in addition, the Heli is flying very slow at Loiter (even if LOIT_SPEED param is set to 1250).Thank you for your help.

Hi,
I started to tune my arduboat the last days. Its equipped with a Pixhawk 2.1 cube and Here GPS.
When I look at the LogFile, there seems to be something strange. X of Mag1 and Mag2 is consistent, but Mag3 has a quite big offset. Is that normal?
And I´m wondering which stated Mag is which real device? 1&2 internal cube compass and 3 the external Here? Or 1 the Here and 2&3 the internal?Thanks for any advice.

Hello. Has anyone encountered this problem? Formatted a SD card (4GB U3) in the format of FAT or FAT32, inserted into the flight controller. When I try to disarm, I get the message PreArm: Logging not started, when I try again, the message PreArm: Logging failed. I take out the card, insert it into the card reader and ask Windows to format it.
I tried to change the settings of log types, bit mask, logging buffer size (after each change the controller rebooted of course) and nothing helps. I would appreciate any help

Hello everyone.
I wan to convert this Hobbyking h600 to a y6 and need some advice on FC placement.
The distance from the middle of the front motor to the middle of the rear motor 72 cm. Am I assuming correctly that halfway 36cm, would be the center of thrust and that this is where the FC need to be placed, or do i need to place the FC as close to the CoG as possible?

Does anyone have this file, or have a suggestion on this task, or can someone suggest an alternative way to simulate my personal drone? Any help would be well appreciated.
