Hi all
I seem to be having a problem connecting to blheli suit through Pixhawk cube runing arduplane 3.93, what I am missing? Everything is working if I flash it with arducopter… please see attached screenshot.Thanks in advance for your response.

Hi all,
Just jumped into the world of arduplane and wondering if we can control the airspeed OR Throttle (on the go with transmitter)while flying a fixed wing in Cruise or Loiter mode?Thanks.

So I’ve gotten my vectored yaw quadplane tiltrotor flying in Q_Stabilize and Q_Hover. But I’m seeing some behavior that I don’t understand whenever I try to switch to Q_Loiter. For reference, my setup is a quadplane with the front two motors tilting and the rear two motors fixed, on arduplane v3.9.3.
Basically, whenever I put the aircraft into Q_Loiter, the tilting mechanisms become linked to throttle. At minimum throttle, they point straight up, but they tilt forward as you advance throttle. They stop at around 45deg, at half throttle. Moving the throttle stick beyond that has no additional effect. At first I thought that the q_tilt_max parameter would have an effect on it, but it does not. I also thought that the q_vfwd_gain was involved, but I have that feature disabled.
The one thing I CAN tell is that it’s linked to the vectored yaw settings. Setting the tilt type to continuous eliminates the behavior, and my other VTOL (a similar configuration tiltrotor with non-vectored tilt) does not have this issue.
I’m tearing my hair out trying to figure this one, as none of the quadplane params I’m aware of seem to have any effect on this. Could it be a bug? I know others are having successful flights on tiltrotors using vectored yaw, but I don’t know if any of them are using Q_loiter. Any input from those people would be appreciated.

Hi all,
Please advice me if i can do auto takeoff from the park grass using arduplane?My plane doesn’t have a tail wheel.Just ailerons and rudder and it takes off okay in manual mode from its belly.It has enough power to take off from the grass.
But it would be nice to have auto takeoff as sometimes its hard to point it straight while taking off using manual mode.Thanks.

Is there a setting in the 3.9 release (or any prior) that I’m missing to allow for PID Attenuation using input from a pitot airspeed sensor?
Control throws need to move a lot at low airspeed so the P term would be very large, but at higher airspeeds the control surfaces need to deflect very little to achi be the same correction.
My fixed wing flys fine in Auto or FBW modes at low to moderate airspeed, but when I fly at what I believe to be higher airspeeds or in a dive, I start experiencing a wobble that can turn into a P term oscillation.
Please forgive me if I have missed this in the release notes or as a feature & direct me to the parameter field where I can utilize this PID attenuation feature in the params.
If this does not exist, can this be added to the code as a feature in a future release? I would think it would be similar to the TPA (Throttle Point Attenuation) like on my miniquad running Betaflight.
Thank you,

I have been looking at Peter barkers code found in this link:
Peter, So I am wondering if I am thinking about this right. It looks like you are creating a list of commands and saving them in the cmds variable. You then upload them via “cmds.upload()”. By doing this when you put the plane in AUTO mode it should take off, fly to a way point, then loiter. Is this right?
I am kinda stuck on getting the plane to actually take off or move for that matter. I am using the sim_vehicle.py. I attached the code I pulled from your page.

Hi all,
I am trying to control the roll of a plane using mavros and in particular the topic /mavros/setpoint_attitude/attitude. This is basically the code I am using:
ros::Publisher mav_att_pub = nh.advertise<geometry_msgs::PoseStamped>( “mavros/setpoint_attitude/attitude”, 100 );
ros::Publisher mav_thr_pub = nh.advertise<std_msgs::Float64>( “mavros/setpoint_attitude/att_throttle”, 100 );// attitude geometry_msgs::PoseStamped cmd_att; //throttle std_msgs::Float64 cmd_thr; // Create attitude command message cmd_att.header.stamp = ros::Time::now(); cmd_att.header.seq = count; cmd_att.pose.position.x = 0.0; cmd_att.pose.position.y = 0.0; cmd_att.pose.position.z = 0.0; // here your desired angles tf::Quaternion mav_orientation = tf::createQuaternionFromRPY( 0.6, 0, 0 ); cmd_att.pose.orientation.x = mav_orientation.x(); cmd_att.pose.orientation.y = mav_orientation.y(); cmd_att.pose.orientation.z = mav_orientation.z(); cmd_att.pose.orientation.w = mav_orientation.w(); mav_att_pub.publish( cmd_att ); // here your throttle value a [0,1] cmd_thr.data = 0.8; mav_thr_pub.publish( cmd_thr ); ++count;I hardcoded some values just to try but unfortunately the plane does not respond to these messages. I am currently using the SITL. I tried with mode AUTO and GUIDED but the plane still do not respond to the messages.
I have also set the parameter setpoint_attitude/use_quaternion to true as described here http://wiki.ros.org/mavros#mavros.2BAC8-Plugins.setpoint_attitude.
I am using the latest ardupilot code (master) from github.
I am very new to mavros/ardupilot so any help would be appreciated.
Thanks!

Hi,
The application below for the Matek F405 Wing looked interesting so I decided to create a conversion thread. On top of the added integration, it has the 7 outputs needed to convert the Convergence VTOL to APM. The mini Pix layout below still has the lowest combo price but it is limited to 6 outputs and is not always the best fit using JST GH connectors and less integration. The PixFalcon option does have 8 outputs but it is twice as expensive and not as integrated as the Matek.
My goal for this project is to replace the stock E-flite Flight Controller with a Matek F405 Wing controller and then add the appropriate FPV gear with OSD.

I try to run the SITL in the simulation tab, after i build it in visual studio 2017. When I run it, I get ‘System.AccessViolationException’ in some non-reasonable parts in the code, such as in the line: ‘log.Info(DateTime.Now + " " + sev + " " + logdata);’ (of MavLinkInterface.cs).
I’m using an older version of mission planner (1.3.39), but thats the only version that suitable to Visual Studio who worked in my windows 7. I know you don’t support anymore older versions, but do you have any idea?
Thanks

Hello,
I have a project in university about validation of the plane aerodynamics model. I use the pixhawk to get the flight data. The information in the logs of the the AoA and Sideslip are strangers. Do someone know how the pixhawk estimate this informations, Aoa and Sideslip?

do any one know the definition of stat_FLT TIME, how do flight recorder count the flight time? Does it begins to record the FLT time according to the motor start or the altitude？And please look at the attached photo, the stat_reset is 8.65, what is that mean？

Hi all,
My easystar-II is yawing to left while throttling up due to the motor torque in FBWA mode.But it tracks straight at 0 throttle gliding.So its not trim i guess.I found that the amount of yaw is kind of proportional to the amount of throttle.Is there anyway arduplane can give counter rudder depending on the throttle?Should i try to increase the value of KFF_RDDRMIX?
Sorry i am totally new to arduplane and still learning.Please guide me.Thanks.
