Yea, that would be a good way to present it.

Copter-4.0.1 released!
Copter-4.0.1 has been released as the official firmware for multicopters and traditional helicopters and should be available for download from the ground stations within a few hours of this post.
The changes vs 4.0.0 are in the ReleaseNotes and copied below:
- FrSky telemetry status text handling fix (Critical Fix)
- Circle mode allows pilot control of radius and rotation speed
- CAN servo feedback logged
- Magnetic declination tables updated
- Serial0 protocol forced to MAVLink (avoids accidental disabling of USB port)
- Minor Enhancements:
a) Autorotate flight mode renamed to Heli_Autorotate
b) Solo default parameters updated
c) “Prepared log system” initialisation message removed - Bug Fixes:
a) TradHeli RSC RC passthrough fixed
b) CubeOrange and Durandal I2C timing fixed (was running slow)
c) Compass calibration auto orientation skips “pitch 7” which could cause cal to fail
d) Durandal’s fourth I2C port fixed
e) Linux boards with CAN support fixed
f) Neopixel added to SERVOx_FUNCTION param description
g) NMEA Output fixed (was sending an extra CR)
h) Optflow messages sent even if EKF has no height estimate
i) SkyViper build fixed
j) Spektrum/DSM 22ms RC input fixed
k) “UC Node Down” message removed (was unnecessarily scary)
l) Semaphore fixes for Logging, Filesystem and UAVCAN Dyanmic Node Allocation
m) RangeFinder parameter fix (4th rangefinder was using 1st rangefinder’s params)
n) TradHeli STB_COL_x parameter description fixed
The most important change is “1) FrSky telemetry status text handling fix (Critical Fix)” which resolves the critical issue announced in this blog post.
WARNING: we have seen two reports of CAN compasses not being recognised at startup unless BRD_DELAY_MS is set to 5000. This parameter slows down the autopilot’s boot time (by 5 seconds) which gives more time for the CAN peripheral to startup. This is not a critical “bug” that should lead to crashes but we would like to hear from users if they are having troubles with CAN compasses being detected.
Special thanks to our beta testers for testing this release over the past few weeks. You are a critical part of the process and we really appreciate your help! Thanks!

Can SBUS Out (SBUSo) and AUX pins be used simultaneously?
I want to control a Gremsy gimbal and a Seagull #REC together via a Cube . So far, I enabled SBUS out (BRD_SBUS = 1) and connected the gimbal using SBUS which works using Ch 8-11. I need 3 more channels to control the Seagull #REC and had hoped to use AUX Pins 4-6 but can’t get it to work.
Is it possible to use SBUS out as well as the AUX pins? I have tried setting the appropriate SERVOxx settings to RCINxx, RCPassThru, and disabled but no luck and run out of ideas!
Anyone out there able to help with this?

HappyModel PixRacer R15 Inquiry
I’m looking to build a FliteTest Mustang P51D as my first scratch build, and I think I’d like to have ArduPlane along for the ride. I currently have a Pixhawk1 sitting around, but I feel it is simply too large/bulky for such a small build.
I’m quite tempted by the PixRacer R15 by mRobotics, but budget dictates I should look for a deal where I can.
Enter the HappyModel PixRacer R15 on eBay.
Does anyone have any experience with these? Trash? Acceptable?
Thanks!

Unwanted Yaw during auto missions
This seems like the only parameter that would make sense to me… Have you played with any of them yet?
AHRS_YAW_P: Yaw P
Note: This parameter is for advanced users
This controls the weight the compass or GPS has on the heading. A higher value means the heading will track the yaw source (GPS or compass) more rapidly.
| Range | Increment |
|---|---|
| 0.1 - 0.4 | .01 |

HappyModel PixRacer R15 Inquiry
Good day, the flight controller you have found on eBay its not the version r15… inside that cover you will find the version r12, the original pixracer is released by mRobotics, if you will compare the one on eBay with the one of mro you will see that the hardware is totally different. You can look also for the mRo x2.1 or x2.1 777… more redundant and more capabilities.

WS2812B (NeoPixel) Integration
Wait a minute. On the Pixhawk, both AUX and Main signals come from TXB0108:
( 8-Bit Bidirectional Voltage-Level Translator with Auto-Direction Sensing and
±15-kV ESD Protection)
with separate VCCA (recommended 1.2V to 3.6V) and VCCB (recommended 1.65V to 5.5V), but both are connected to 3V3.
Vohb has minimum VCCB-0.4V, roughly 2.9V (low).
So it seems that if VCCB were connected to J901-VCC (moreless servos/ESC’s external supply) no level translator would be necessary, but this implies a redesign of the PCB.
Output signals would be truly 5V (or external supply). Any drawback?

Heli Setup page and Helicopter 4.0.0 fw
Great work. I am not at all an helicopter expert, but second page is more clear.
A great thing about Tradheli is that knowing almost nothing about helicopters I could do a mission on the first trial (on a windy day), although there was a ROI forgotten problem.

HC-SR04 Alpha Module (I2C) with Pixhawk
Good day,
HC-SR04 doesn’t perform well due cone reading limitations… you can use maybe as landing sensor but not for obstacles avoidance. If need an obstacle avoidance you must look for Teraranger tower or SF40c

Beside logging and reporting of protocol used,
In case of DShot, does it use full 2048 steps resolution or the same 1000 steps range, just in digital representation?

Very weird problem acceleration
thank you Wicked ! and Randy,will look at those parameters later today and also will do an autotune and will report back yes it was in stabilization

PID tuning for heavy quadcopter
Hi,
I want set Pid Parameters, my Quadcopter is heavy, it Octa qua frame about 12kg and 24" props. motor is 250kw and 6s.
Someone has an example setting Pid for heavy Quadcopter ?
Please tell me if you have any experience,
Thanks Dev team.

Heavy or light, the https://ardupilot.org/copter/docs/tuning-process-instructions.html guide applies to all.

Cześć.Dave.
Could you write what firmware version for pixhawk 2.4.8 (pixhawk 1 or fmuv3, etc) you have installed when you have proven that you have oneshot125? I would also like to ask for a param file or although you have mapped engines. I can’t repeat the oneshot on my pixhawk 2.4.8. Thanks

Lidar in AltHold
@rmackay9,
I took the parameter for rangefinder in SITL from this page, anyway as you said differ only in scaling. I did another test with the params you suggest but the result is the same.
It seems to me that the problems we see on my second test above (with plot and dataflash log) has the same root of the problem on @Frankendrone test: the EKF continue to use rangefinder altitude even when status is not 4 (Good), in my case it becomes 3 (OutOfRangeHigh) over 20m (RNGFND_MAX_CM 2000) and then we see all the weird things.

This is not correct. Someone can use high voltage servos, so if J901-VCC is greater than 6.5V (VCCB maximum rating) U901 and U902 will be blown.
So other 5V internal supply is more appropiate, such as IO-VDD_5V5, VDD_5V_HIPOWER or VDD_5V_PERIPH.
