Why does the VTOL model have a slow climb rate (0.5 m/s) when using a beacon, but climbs at 2–3 m/s when the beacon is disconnected? How can I troubleshoot this issue?

Free STL files now available for download for basic quad-copter - all 3D printed
Over the winter I developed a quad-copter designed to be inexpensive to construct.
The entire frame is 3D printed, and can be used with very inexpensive components.
I’ve made them available on my website, along with some general comments and advice about a build. I plan to used this as an excuse to finally learn the Methodic Configurator developed by @amilcarlucas and include information about using it to tune a quad on this frame.
My goal is to provide another way to help people have an inexpensive way to get started with autonomous quad-copters.
It’s available at Copter Parts – Download STL Files | Copter Cam Tech

Cube Orange+ - No GPS
Hi,
I am trying to build my first quadcopter. I have a cube orange plus, I bought Radiolink TS100 Mini GPS which has Ublox M8 in it. It came with 6-pin JST-GH connector (which is correct). In the wiring diagram for gps it shows VCC - TX - RX - SCL - SDA -GND and Cube Orange’s GPS2 port is VCC - TX - RX - SCL - SDA - GND
So I Changed the TX and RX and also set the baud rate to 57600. GPS’s led is flickering it means it has positioning according to manual but mission planner still show it as a “NO GPS”
Also I can see the GPS in Compass calibration as external compass.
I dont know what to do? I really appreciate help.
Thanks for your time

Slow (delayed) disarm in acro comparing to betaflight
Hi, I’m new in arducopter, and I come from betaflight acro. So I set up ardupilot on my 3,5inch cinewhoop.
I have noticed that disarm happens in 0,3-0,5 seconds after I switch RC thumbler, so my drone remains flying all this time.
The same question is for arming - it happens in approx 3 seconds after I switch the tumbler.
But disarm (as it is about safety) is bothering me more.
Could you please help me to find any options to tune this?

Detect programaly what ek3_source is curently used
Hi,
I am working on visual slam based odometry source. I have managed to use my odometry via mavlink.
I setup
EK3_SRC2_POSXY 6
EK3_SRC2_VELXY 6
and set:
The active set can be selected via an RC auxiliary switch (e.g. set RCx_OPTION to “90” / “EKF Source Set”).
And it even somehow works.
The problem I have, then pilot switch ekf sources, information is shown in Ground station, but as log message, and this message sometimes is missed by pilot, specially then he switch sources online.
So It will be good to have capability to know witch source is used, and also it will be very use full to have access to this information via mavlink, in such case I will have capability to change some parameters based on source (for example LOIT_ACC_MAX)
So if there is any capability to know what source is currently used programmatically via some mavlink request?

Sideslip transition during crosswind landing
Hello,
Forgive me if this has been documented somewhere, but I haven’t been able to find detailed information on the lateral control algorithm that the auto landing uses during a crosswind landing. I am assuming that it uses a crab technique (wings level, nose pointing partly toward the crosswind) to track the runway heading, the same as during auto flight.
Is it possible to specify a sideslip technique, where the nose remains aligned with the runway heading, and bank is used to compensate for the crosswind? This is a common technique in full size aircraft, and something that would be useful for larger airplanes, especially taildraggers.
My goal is to demonstrate smooth, accurate, controlled landings on a taildragger up to 25kg in crosswinds up to 11 knots.
Cheers,

RTL dives to RTL_ALT, does not descend linearly as documentation says
Hello,
My VTOL T1 Ranger (arduplane firmware 4.5.7) dives at pitch limit to RTL_ALT if above RTL_ALT when QRTL activated. The documentation says it should linearly descend to RTL_ALT if above RTL_ ALT.
Is there a parameter to determine if plane should go straight to RTL_ALT or linearly descend to it based on distance from RTL?
Thanks in advance.

Change the VTX power according to the quality of the received signal
I am trying to set up a FPV aircraft with head tracker. These are the components: FC Matek H743 WING V3, Pitot Tube AS-DLVR-I2C, GNSS and Magnetometer Matek M10Q-5883, CAM Foxeer Razer V2 Mini, VTX Rushfpv Max Solo, FrSky Archer R4 receiver.
Using the VTX data cable connected to the FC is it possible to modify the VTX power based on the quality of the signal received? If so, how?
Thanks

Cube Orange Plus Shutdown when Holybro Remote ID Connected
Hello,
I have a Cube Orange+ that I am utilizing. When I connect the flight controller to power the flight controller starts up just fine.
As soon as I plug the Holybro Remote ID module into the GPS2 specifically, the flight controller basically shuts down all power to ports. I have no idea why it is sensitive to a connection to the GPS2 port, I am hoping someone can shed some light on this.
Stable:
Unstable:
Configs:
copter.param (19.7 KB)
Again, note that I am only changing the input port on the flight controller and nothing else. Immediately, the light blue LED indicators come on and the flight controller eventually shuts down power to the rest of the ports.

2 IMU Vibe Z values change between the two IMUs Matek 743
I got a strange situation with the two IMUs (Matek 743). At the beginning, the Vibe Z of both IMUs were very similar, but reviewing a recent log I got values which are like 30 for the first IMU, and 7 for the second… What does it mean?

Reset SITL session in Mavproxy
In there a way to quickly reset a SITL session in Mavproxy (for example after a crush) ?
What I do now is CTRL+C at the terminal and then run sim_veichle.py again and I want something quicker.

Quadplane can't takeoff as VTOL
Hi everyone. I’m new to SITL and I tried to perform basic quadplane setup. I used Q_ENABLE = 1, Q_FRAME_CLASS = 1, Q_FRAME_TYPE = 3. Also set up Q_ASSIST_SPEED as 15 m/s, Q_OPTION (5), and ServoOutputs. Unfortunately, every time I start mission (which begins with VTOL_TAKEOFF) drone just stays on the ground. I also tried Q_ENABLE = 2 and set up VTOL_TRANSITION right after VTOL_TAKEOFF, but it didn’t help. Drone takes off in simple TAKEOFF flight mode, it follows waypoints, but when it reaches VTOL_LAND/RETURN TO LAUNCH it just begins to CIRCLE. What do I do wrong?

Connecting two Pixhawk-equipped to 2 different aircraft to a single Mission Planner instance
I am working on creating a two-plane swarm using Pixhawk 2.4.8 and need help connecting both Pixhawks to a single ground station (Mission Planner). My goal is to designate one aircraft as the leader and the other as the follower. Is this possible? If so, how can I achieve it? I am new to this and would appreciate any guidance.

How to Run Multiple Vehicles (Rotary-Wing, Fixed-Wing) on Gazebo with ROS2 and ArduPilot?
I already have the Copter system running, and now I want to add a Plane to the simulation.
I’m unsure how to modify the launch and world.sdf files to set up the environment for this. Also, I don’t have a Plane model.
I’m really stuck on this, and any help would be greatly appreciated.

Recommendations raspberry - pixhawk
Hi!
I am trying to make an autonomous quadcopter that could avoid obstables using computer vision. I am using a raspberry pi 5 with the pixhawk and mavproxy. My idea is to use a RGB camera ( I can´t afford a stereo one) to process the obstacle and send commands to the UAV to avoid it. I want to use ROS2 to make it (take the image, aply the algorithm, calculate deph and then send a MAVlink message to the autopilot), but I dont know if there is another way to make this easier. I only want to make it in a straigh line and use an ultrasonic to measure the distance with the floor.
Someone knows another way to make this instead of using ROS2?
Thank you!

The hobbywing x9 and ardupilot also make vertical flicker
Hello.
I made 2 Quadcopters with X9 Motors on the chassis of EFT.
I have X7 + Pro Flight controller in the configuration and I have no compass problem with Baseline yaw heading.
- There is no problem with the device and it flies very well.
My other device has a vertical vibration starting after 40 seconds of the video.
https://www.youtube.com/shorts/IUGt7nlMeHY
I am doing ArduPilot methodic configurator manually but I need to fly stable in ALTHOLD mode for NORCH filtering but it vibrates in althold mode and I could not find the reason.
I think the vibration values are at an acceptable level.
I have successfully flown many devices on ardupilot but I need your help on this one.
I would appreciate your help.
I am sharing the log file with you.

X Quad Tends to Flip During Takeoff in Stabilize Mode
Hi,
The attached log file is from my vehicle’s first flight. The issue is that the vehicle tends to flip over during takeoff in Stabilize mode, but it can take off in Loiter mode. Because of this, I don’t think the problem is related to motor configuration (I’ve already checked it). I also verified the CoG and frame type.
Could this be resolved by running an autotune on the vehicle?
Thanks.
Initially, I tried to make the vehicle take off in Stabilize mode, but since it started to flip, I switched to Loiter mode, and it successfully took off. I’ve just set the initial parameters.
