I have six Turnigy Plush 18amp ESCs. When running motor test in Mission Planner three of them will spin at 5% throttle but the other three require 22% throttle to spin. All of them are programmed the same with the Turnigy programming board. Oh, yes, I’ve calibrated them for high and low throttle. Scratching my head.
This is a quad with a Pixhawk FC (PX4 V2). Arducopter 3.6.4. Latest version of MP.
Any ideas?

I’m working on a VTOL concept with eight vertical motors along with forward motors. I’m trying to configure it as a QuadPlane but am having issues with getting the vertical motors to output properly. Whenever I arm the vehicle, a seemingly random arrangement of motors spool up. After repeated trials, I have seen configurations ranging from two motors to all motors spinning (rarely).
My ESC’s are calibrated and all run in sync. I can verify this with an RC3 passthru to all servo channels. The motors are on channels 5-12 (Aux channels 1-4 on the Pixhawk 2.1). The servo functions should be mapped properly. I have also disabled all the servo functions and let the autopilot map the motors, which wound up at the same mapping I had. As I said, I know that each individual motor is able to get a signal.
I’ve also flown the copter with ArduCopter firmware. Everything works fine there. Then I switched over to ArduPlane V3.9.4 and started seeing the issues. I’m wondering if it’d be a good idea to try the ‘master’ branch of ardupilot. It seems that a lot of work is being done on QuadPlane at the moment.

I cannot figure out what I am missing. Help would be greatly appreciated.
Thanks!

Hi!
I have set-up Gazebo with SITL by following this link and I am using Dronekit-Python to perform missions in Gazebo.
The camera gimbal rotation commands through Dronekit or through MAVProxy terminal are reflected in the vehicle’s gimbal attribute (vehicle.gimbal) but the gimbal does not move in Gazebo and the camera view does not change. Gazebo throws no error (when run with the --verbose flag) so I am assuming that the gimbal_small_2d plugin is loading successfully. All the other functionalities are working i.e. the drone is flying in Gazebo as it should. But the gimbal is not moving at all.
Can anyone please point me to the problem?
Thanks

Hi everyone
I am new to apm and building drones. This hexacopter is my first build although I have a couple quads and a phantom 3 pro. I have been using betaflight for the quads with good success but that’s still a learning process. The hexacopter I am having issues with is with Mission planner.
The build went great, everything install nice, props are rotating in the correct directions.
When trying to take off, the hexa pitches forward each time… it’s never been off the ground
I have gone through the programming several times. I have checked the compass and gps. I have aligned and realigned a lot… I have looked at the physical balance of the hexa as well.
I am at a loss… Help please. What have I missed? I want to build a heavy lift octocopter in the near future but need to get past this hexacopter step.
Any of you in the vancouver area?

First, I apologize if this is in the wrong section, I did not see a section under hardware for the Pixhawk 4 or specifically for ESC issues.
I am trying to get to my first flight but am having difficulty calibrating the ESCs. My setup is as follows:
- Pixhawk 4 with Holybro Power Management Board (https://shop.holybro.com/pixhawk-4beta-launch_p1089.html, see the 3rd image for a picture of the power board)
- Ardupilot V3.6.4
- Turnigy Multistar BLHELI_S 40A ESCs (https://hobbyking.com/en_us/turnigy-multistar-40a-blheli-s-rev-16-esc-opto.html)
- Taranis X9D+ transmitter
- FrSky X8R receiver
Everything calibrates without issue except the ESCs. In Mission Planner, I can see that the output to the ESCs is correct when I apply throttle on the transmitter. When I try to use the ESC calibration feature, nothing happens. No beeping from the ESCs at all.
I was successful in manual calibration on 3 of the 4 ESCs when I connected them directly to the receiver, bypassing the Pixhawk 4. I believe the 4th is defective and am getting it replaced under warranty. Since manual calibration seems to be working, I think I have some issue happening with the Pixhawk 4. Wiring is as follows (also see images of my setup below):
Pixhawk 4 “FMU PWM Out” --> Power Management Board “FMU-PWM-in” --> Power Management Board “FMU-PWM-out” --> ESC connectors

Any input would be appreciated. I have been struggling with this same issue for the past 2 days now and am nearly out of ideas.

Hi, im about to update the firmware of arducopter from 3.3.3 to 3.6.4
I have the full parameter settings of 3.6.4 saved in a file
My question is that do i have to load the settings before i do a compass calibration and a motor/compasss calibration?
cause if i load the settings file after the calibration procedures wont the offset values overright?

Hi All
I have a feature suggestion:
At the moment in rover there is only Hold and HoldAndDisarm for crash check action.
I would be very much interested to have two different Crash check action.
- As it is
- A delay time were the rover goes in hold and then tries to complete the mission or repeats the delay-hold-auto cycle a configurable number of times before it goes to 1).
This would increase the reliability for long mission for example with boats where the craft can hit an object and may get free by going to hold a number of times and could complete the mission successfully.
Thanks a lot

Hey everyone, long time reader and first time poster. I have the sky viper 2450 fpv which is almost the same, my question would be the same for either drone anyway. I have been having trouble with the onboard SD card, I can get about 2 minutes of video (it’s like 15-20 degrees outside now) but after the low battery beeping comes on it seems like it quits recording. I fly for over 5 minutes after the low battery beeping comes on and have the camera running the whole time I think but I’m only getting a couple minutes recording out of the camera. I have the highest write speed and a 32 GB Card with almost nothing on it.Does the low battery beeping shut the camera off? It starts beeping after a few minutes but I can fly about 3-4 minutes more after (no it’s not the video recording beep, that’s much different).
Another question I have is about something in the instructions, it says for an emergency stop to “hold down the stunt button (for drones that don’t have a stunt button, use the video button) and move both thumb sticks down and away from the center of the controller” (NOTE: my drone has a stunt button) anyway when I use the emergency shutoff it doesnt do anything, sometimes it tries to do the stunt/barrel roll/flip thing and sometimes it veers off to the side from the stick input. I have tried different timing and everything and can’t seem to get it right. Sorry to thread hijack but could anyone help? Thanks!

Hello All!
I am trying to port latest ArduPilot to this board: STM32F407VET6
This is not exactly a Copter board, but I have it. It has mini-USB, microSD card slot, and Flash chip on board.
*Edit: Here’s EasyEDA link to schematics https://easyeda.com/rossos/stm32f407vet6-ebay-board-stm32f4xxI have watched the video at http://ardupilot.org/dev/docs/porting.html and learned about the migration of the project to ChibiOS and its simplification regarding porting to new hardware.
I’ve made a hwdef.dat file for the board here: stm32F4ve/hwdef.datThe plan was to also use stm32f103 for FMU_IO in the long run, however for now I want to focus on the main board. GY-91 mpu9250+bmp280 board is to be primarily used. Also “NEO-M8N Ublox GPS Module w/Compass +GPS for APM2.8 APM2.6 Pixhawk”.
I have tried to retain the fmu_v3 pinout as much as was possible.
However this board has build in Flash chip on SPI3, which is one of the major deviations so far.
Also, I am confused regarding the PPM/SBUS input pin, I lean towards PC7 which is also USART6_RX but that was giving me errors.The main challenge I am facing right now is that this board has only 512kb of memory, and my successful compile ends up being 988024.
During compilation of 506 steps/files I have noticed that it compiles a lot of things I wouldn’t necessary need.
My question is: is it possible to disable modules/features to lower the size to ~500kb?Thank you in advance.
Best regard,
Rossos

Hi All & Happy New Year!
Wondering if a lipo battery of this size & power could potentially fry the APM 2.8. Here’s what I want to buy:
Power Module that I already own:
powerday APM Power Module V1.0 XT60 Plug for APM2.8 APM2.6 APM Pixhawk Flight Controller
-Specifications:
-Max input voltage: 30V
-Max current sensing: 90A
-Size:25219mm
-Net weight:25g
-Voltage and current measurement configured for 5V ADC
-Switching regulator outputs 5.3V and 3A max
-6-pos DF13 cable plugs directly to APM 2.5’s ‘PM’ connector
-Note: The Power Module is only designed to power APM, a RC receiver and
-APM accessories (GPS, 3DR radio). It isnotdesigned to power servos. Use your aircraft’s own ESC/BEC for that.
-The maximum input voltage 20V, maximum current measurable 90A, to achieve the control panel on battery power and voltage monitoring. The design parameters of voltage and current detector design parameters consistent with 3DR official ground station (mission planer) settings can be set directly refer to the official Wiki.

Right now it appears that Most GCS use this “User” field or the actual parameter name to sort/identify critical parameters and those that should only be changed by advanced users. Is there an easier way that could help everyone out rather than the binary Standard/Advanced user field?
Something that came to my mind was Tags. Parameters that are changed often could be assigned tags that help search or categorize them. It would help group critical parameters during tuning time.
For example, when I am tuning planes for landing, I need both LAND_ parameters and TECS_LAND parameters. In addition, a few other useful parameters such as LEVEL_ROLL_LIMIT and USE_REV_THRUST would also be applicable. Each of those parameters could have tags, one of which could be a // @Tags: field that would include words separated by commas or semicolons to assist in grouping parameters that may not be in the same class.
Some group tags that come to my mind would be Takeoff, Steering, Attitude, Speed, Navigation, Altitude, Failsafe, Safety, RTH, Input, Output, etc. What do you think? Would this help new users find the right parameters to modify without searching through nearly 1,000 parameters?

Greetings!
Can anybody suggest me a very long range 433 MHz Telemetry pair for Pixhawk 2.1 Cube?
Currently I’m having 3DR module of 500mW. But I need to communicate with my ArduPlane with maximum of 100 km without satellite communication.
I cannot use 900MHz because of rules and regulations in my country.
Thanks in Advance.
Good day.
