Hi
TVBS test.param (16.4 KB)
I’m facing an issue with my ph4 mini.
I have it set up on a fixed twin motor tilt rotor.
My issue is that any port assigned to function 75 and 76 (lilt motor left and tilt motor right) show a pwm output value of 0.
Picture for reference and parameters attached
any help is greatly appreciated

Such as the title
I flashed the firmware in the first time when F4 Flight Control ported APM，At that time, the RX is still working normally on there.
But after the last upgrade, I can no longer connect to my receiver. Whether it is s.bus or ppm.
I saw that most of the forums are about the V3 version. But the difference between V2 and V3 is only a Jumper pad？
I am troubled. Hope for reply。

Hi all, My Easystar-II with OmnibusF4ProV3 was behaving abnormally after i switched from FBWA to loiter and cruise mode.It was trying to stall.Then i landed it and took off again and all was fine after.Only thing i am suspecting moisture from the grass entering the pitot tube as grass was quite wet while taking off.I am attaching a log.Could anyone please have a look?Thanks.
Here is my log: https://drive.google.com/file/d/1JnamwtbKhD5ybZvujajhHe4sV4I0f4rS/view?usp=sharing

I have some very odd behavior when I set SERVO_AUTO_TRIM to enable on my Nano Talon flying the latest release of 3.9 on an Omnibus F4 Pro V3.
At some point in the flight, often at the very end, but not always, the auto-trim sets the deflection to maximum on my ailerons. The plane does not crash but it starts a violent oscillation as the FC fights this full deflection. It seems it counteracts the deflection and then goes back to fully deflected in an oscillating manner. I but retain control in FBW A. I land, reset the aileron trim to 1500 (center) take off and fly and the same thing happens. Here is a pic of the deflection when I land with my radio sticks centered.
Here is a log of a flight when this happened.
It is not spurious – it happens every flight pretty much. Since I disabled the auto trim setting I have no issues. The plane flies pretty well in wind even – it still needs a proper tune, which I can now do as I have solved this issue. It is a well behaved plane.
None of my other planes exhibit this behavior.I wonder if it is related to the small size of the Nano Talon - cannot think of another reason. I think it is worth looking at as it could have some nasty outcomes, potentially.

I can get X-Plane to output data and mission planner and mavproxy display it. The data is not working the other way. I checked that I am using the ports that are defined in the SIM_XPlane.h file (Port we receive on: 49000, Port we receive on (legacy): 49000, and Port we send on (legacy): 49002) The Data Output>General Data Output>Network Config is fine with port 49001.

Just dug out my old fx61 which has a Pixhawk Lite FC installed (fmuv2 I believe). This has the older 3.8.5 NuttX firmware installed and connected to MP no probs (running in windows 10 VM under VMWare Fusion on my Mac). Then I did the upgrade to current release ChibiOS version (3.9.8 I think). On connecting to windows 10 It seems to connect (chimes), disconnect then re-connect after plugging in the USB cable. Then I get a driver error and no com port shown in Device Manager. I managed to get it connected to my mac and installed the latest release NuttX version of arduplane using QGC, and this now connects fine to Mission planner in Windows (com port recognised as PX4 FMU (COM13)). So I installed ChibiOS version once again in MP, and again can’t connect - again no com port appears - so once again back to NuttX using QGroundControl on the Mac and I’m connected to MP again.
Anyone shed any light on this please?

Just had the weirdest thing. Took our plane (Nimbus 1800 VTOL) for a flight after a few weeks of no flying. Plane had flown fine the last time and hadn’t even been booted up since then.
Armed the plane to do a quick test hover, which was fine, then tried to disarm - and it would not!
Eventually was able to disarm with Mission Planner, tried to arm again and got an error that the trim values were lower than the minimum values.So I checked, and all 16 channels trim values were set to a value of 874! The original values for all 16 channels was 1500.
How on earth does that happen? First time it’s booted in weeks and somehow all the trim values change?
Or is this just another idiosyncrasy of Ardupilot that we must accept?

I can’t find any parameter for configuring DSHOT mode in ArduPlane 3.9.8. None of these described in the ArduPlane docs are present among my parameters.
[MOT_PWM_TYPE], [SERVO_BLH_OTYPE], or [Q_M_PWM_TYPE]
My plane is not a tailsitter, just a “normal” twin-motor airplane. Do I need to enable the tailsitter and then somehow (how?) disable most of it functionalities, but have access to the Q_M_PWM_TYPE parameter?
I use the DSHOT support in my copter, works really great, now I would want to move to the planes with this.

Hi,
I’d like to try quadplane using Cube and big props setup like 27"-29".
Any advice for the start, procedure and settings (parameters, tuning)?
I intend to use FW 3.9.8 and manual tune the quad part.
I’m mainly concerned about the quad ESCs response with spool-up time, spinning props fast enough to follow ATT.DesRoll and Pitch.
I was searching in arducopter section to find some info, but almost everything is related to Autotune (aggr, filt etc).
Questions about filters:
Q_A_RAT_PIT_FILT and Q_A_RAT_RLL_FILT are 10Hz by default. Should I go dawn to 5? Or it only matters with q_autotune in dev fw?
Thanks.

Hi Guys,
Still busy with my quad plane build project, wanted to find out if anyone has any knowledge of configuring in mission planner propellers to be locked at a certain angle after shifting from VTOL to fixed-wing flight mode in order to reduce drag forces? I am using PX4 cube autopilot.

I know this is in the 3.9 category but figured I’d throw up a log of two flights of a nimbus I had sitting in the closet for a cpl years. Figured I’d post them in case there is something useful for the dev’s or maybe folks could let me know what im doing wrong. I had EKF3 enable and AHRS_EKF_TYPE set to EKF3, I did not mess with any of the EKF2 stuff. This is running on a mrobotics pixhawk original. First flight I did an autotune everything went well had some compass issues that needed resolved but it flew fine with the compass issues. Second flight just cruised around tested guided mode, tested the gcs failsafes and everything worked flawlessly, till landing hahaha matted down grass and stumps with flying things don’t work to well, clipped the very edge of the wing on landing tore some glue loose but easily fixable.The link to the files from the two flight are at the bottom.
After the crash I decided to setup this airplane with flaperons after these initial flights to help slow it down on landing (maybe this is not correct). My main reason for using dev is it had the landing gear deploy parameters that are needed on another project just didn’t want to use the other project as a test bed. I think the all up weight with a 14000mah 4S liion battery and a 2 axis gopro gimbal on the nose is around 3500g, all the motors and props are the stock ones that are sent with the nimbus kit (banggood sent it to me by mistake and never charged me). I wanted to setup counter rotating props to help counter act the force the two props create spinning in the same direction but currently the way I see it is when the spin the same direction I only have one critical engine but if they were counter rotating then I would have two critical engines if that makes sense, is there any advantage to have counter rotating props on twin engine electric RC planes?
I do have to say that its quite impressive what the community has done in the recent few months, to be able to take a never flown airplane throw on 3.10 dev that morning then go fly is quite nice. Thanks to all that have contributed.
This was also the first time I used this long range rc/telemetry system, although I did not take it out to 60km due to legal constraints and not having any visual observers posted on some hilltops, it was very nice to have both telem and rc in a nice package, I will try and hit the 60km mark in the next week while I am home at the ranch and can have someone follow it in the ranger while I stay at a fixed location.
You will see in the log file plenty of loiter hahaha I was just sitting back having a grand ol time watching that thing circle above me and I might have had to have a wee sip of
LOGS:Nimbus_1800_3.10devSorry I don’t have any video because someone forgot the camera case at home hahahaha!! I also used a simple bungee launcher that I am really beginning to like. All it is is a dog leash anchor and about 25-30m of speargun bungee cord. I printed off these from thingiverse to attach the bungee cord to and have not had any failed launches so far, compare with trying to just throw the damn things!!

I’ve been out testing a new build of a Skywalker X8 quadplane and it’s been flying great! Yesterday I was testing battery low voltage tripping a failsafe set to RTL. The plane flew back towards me but didn’t stop at the home point and continuing on past me. I’ve never had this happen before so I was a bit stunned. I probably should have switched modes to FBWA but instead I guided it back just using the sticks. If I let go of them it tried to take off again but I managed to get it close enough to do a manual landing. I think that I switched it to QRTL manually or Stabilize but I managed to land it.
I was flying an auto mission at the time and throughout the flight I received a few GPS errors. The plane was flying fine and hit all the waypoints so I let it continue on. I’m wondering if this what caused the issue with the RTL? If anyone has time to look at the logs I’d appreciate some feedback. RTL has always worked rock solid for me and extremely accurately so I was caught off guard by this.

Just moved to 3.9.8 and discovered a major safety issue.
If the plane is powered up and the transmitter is in Manual mode with the throttle raised the plane engine will run while motors are disarmed.
The issue is reproducible.
If the throttle is raised slightly the forward flight motor will only turn for an instant but if the throttle is set to full the engine will run for as much 30 seconds!
To reiterate…
Immediately on power up the forward flight engine will run at full throttle without arming!
