Should have just asked Trappy to bind to his own radio. Tango 2 has ELRS, right? :))

Hi Andy. It seems to me that receiver is not included in build. At least I did not get one. I notice that Holybro listing it as RadioMaster R81 Receiver . What kind of receiver you got and where you got it, that can fit with x650. Thanks again for help.

Thanks, i will try this approach with a speaker. The idea of an impulse hammer is you get a white input. A chirp would do good to. I am not sure about the ardupilot FFT, and may take more time figuring out than just doing a spectrogram with python; i might just do that. Usually the vertical axis is content and horizontal axis (line number) is frequency, so not sure about the output. On idea you might try is suspending the craft by very elastic bungees just above the speaker so the boundry condition is reflective of flight. Another is the FFT resolution is inversely proportional to window size, which in this case amounts to the sample size; may want to use 1024. 7.5 Hz is pretty big. These would allow you to more precisely identify the resonance, and narrow up the notch. Anyhow thanks a lot for sharing all this stuff. I am guessing you are an engineer?

Ah,,,, nice view indeed, but interference

Hi Andy, Great video.I have few questions if you do not mind. 1.) I am building exactly X650 but with Pihwahk 6C, and in my kit I never get EBEC. Is that component only for 6X or Holybro miss to send it. Can I connect X650 without that? 2.) Pixhawk 6C is much smaller then 6X and those install screws for 6C as well as your 6X are not included. What is the size of those small screws for install? Now they added sticker with drilling pattern as there is no way to align holes on plate. Is it possible just use double sticking tape or I should make holes in plate and get correct screws? Your thoughts? 3.) on 1:02:25. you are connecting wires from motor to 2 different boxes next to EBEC? Could you explain me what is the neme of those boxes and is there specific sequence how to connect those wires? 4.) I do have telemetry modules and antennas, where is the best location to install these items? You see I never get any instructions with drone to follow up. and your video is only guidance I have. I do greatly appreciate your help. This is my first build of drone and this is learning project for me.

Thanks for this. You sound like a serious guy. You might want to invest in a modal impact hammer for airframe testing. At 75 Hz, why not just use a low-pass filter? I don't think the controller loops need to respond to anything anywhere near that high. I think the answer is because you only have notch filters to set?

Greetings Andy Piper, When I set compass_orient 100 i reboot and it says 102. never see the sompass_cus_yaw etc? Found it, after ARDUCOPTER 4.2 params are others. I watch yor work with pen paper and soldering iron, Thank You!

Thank you for this insightful video. It is a godsend. I am currently working on developing a custom flight controller based on the STM32F745. In my research, I've examined the hardware definition files( _hwdef.dat_ ) from reputable flight controllers such as those from Mateksys and the fmuv3. However, I find some aspects challenging to comprehend, particularly the assignment of port numbers (e.g., GPIO(50)) to PWM pins and their significance. Additionally, could you please confirm if you are using WSL2 on a Windows machine for this video demonstration or a virtual machine like Virtualbox?

With HDZero!

Nice flight demo.

Looks pretty stable! Are there any future improvements planned for a faster stabilization loop? Could you record a video showing the stabilization rate analysis from this flight?

Can you use the AM32 passthrough for the online configurator with the motors connected to IOMCU? I have not managed to do so, however it works flawlessly when i connect the motors to the FMU port. But then again i cant use FMU (5-8) for the LED's with lua scripting since FMU7-8 don't support DMA (and it doesn't work on IOMCU either). I'm kind of torn between these two options since it can be very handy to easily access the AM32 configurator when using motors on the FMU but then I wont be able to control the LED's.

My "stabilize pitch(error to rate) accel MA" does not go above 297466. MP1.3.82 Arducopter4.5.6

Greetings, hope you are all right. I build quadcopter but cant get it to pos hold, it gains altitude fast. Any guidance?

Have been following your video in setting up notch on holybro x500 with Pixhawk 6c. Your filter setup gives very nice smoother flying performance! When looking at gyro noise with ArduPilot filter tool, it appears that there is some unfiltered noise at 4th harmonic. Would it be safe to filter 4 harmonics (4 motors x 4 harmonics x 3-triple filter, 48 total filters) without overloading processor? They caution about this in ArduPilot setup instructions. Any insight would be appreciated. Thanks again for super video.

Hello from America 🇺🇸, When I use Mission Planner on Android, as soon as i try to connect with my Holybro H743 mini flight controller , it exits the app. Please can you help

Wow, that really looks responsive. Thank you for sharing your hard work with us, i really appreciate it

I'm very interested in this and if you could build a Flywoo Explorer LR 4 for long distance with Arducopter and a Holybro Kakute H743 mini flight controller

Is there a reason that you prefer props in vs props out? Props out keeps stuff like grass and rocks from hitting the camera

I'm also building this drone with the Pixhawk 6X and a GPS-RTK setup. I enabled DShot control of the ESC following what you did in this video, and the motors seem to be working. Interestingly, when I changed from PWM to DShot, the color of the neopixel LEDs changed. I had them set to "Outback Challenge" (green disarmed, red armed) which was working when PWM ESC control was being used. When I changed to DShot, the colors have changed to red when disarmed, green when armed. No other changes were made to the parameters. Bug? Operator error? I'm not sure.

I truly thank you for making these videos. I am new and trying to learn. I am building a Flywoo Explorer LR 4 for Arducopter with a Holybro H743 mini flight controller. I am building it for lightweight, cruising and long distance flying. My question is do still have your files for your Holybro H743 mini and what other parts would you recommend for my build? You are my goto for Arducopter knowledge

tell me you're single without telling me you're single

This a great video. I am following your setup for my own holybro x500. Have just succeeding in getting the Bluejay flashed and can see motor speed in telemetry file. Will now setup filter and do test flight. Thanks much.

I see the same behavior as on my 7" drone: drone rotation is too tough so rotation ends even with some rebound. Do you see this as a problem? If so how to solve it?

Great video! Any chance you could share the parameter list for your X650 build? :D

Is there somewhere I can ask a technical question?

Have you ever tested the Flywoo m10 mini with compass

I have just completed my Build on the X650 Frame. Very nice frame, but not Cube Friendly 🙂. Also not able to get the LED's working on the Cube Orange +

Another question. I noticed that you used the "dshot" method to setup your escs with your 6X flight controller as opposed to one could say the "conventional method". Can one also do this with the 6C controller. I believe that the escs are the same hardware in the holybro kit. Thanks.

Andy, thanks for the great video. I have the exact same drone and have just switched from PX4 to ArduPilot. Now I'm trying to do some tuning. I was wondering if you could share your tuning parameters from video? Thanks again.

Exellent video

What's the quad doing the follow Andy? I'm looking for something that can go this fast.

Hello Andy, can you please put a video showing how you calculated PSC_VELXY_FF using logs.

Apart from an interesting intro to AM32, this is a great general ArduCopter setup video with some great problem-solution moments for many little things that have definitely caught me out when setting up a quad. Great video Andy!

Hey Andy 2:43 , if you dont throttle up then pitch/roll the adjacent motors stop! I about to revive an old tarot hex for some surf fishing 😅

Nice, Cheers

Andy, sorry for the late post, but I had seen your earlier videos with Lee about tuning the Heewing VTOL, and asked him what the status was. He intimated that your work had likely been incorporated by Heewing into their current T1 Ranger VTOL PNP kits. I just received my PNP kit from Heewing and assembled it and programmed it according the Heewing directions, but have not flown it yet. Can you confirm the Heewing is using at least some of your parameters (their current version is AP 4.3.5)? Any suggestions for further noise filtering and PID? Thanks!!!

I had noticed Ardupilot aggressive taking off the ground since 4.3. in your video I saw the same. Is there any param to take off smoother. Big copter is scarry.

will m9 be better since it has higher update rate?

I think you need an example of let's say a perfect 2 gps with perfect accuracy first to have a good understanding, 2 gps that close is not really a good idea tbh

do a disarmed log and ground a data pin or just unplug to determine gps id

Nice to see you just having fun and not teaching us. There is no doubt we need your help, but not every day. Send us one or two of these mixed in with the hardware videos. Cheers!

i used betaflight , and now trying to use inav 7

🎉

Maybe it’s just me, but I can barely hear you.

amazing work Andy!

Is the horizon ment to drift that much on osd

Thanks. That's pretty impressive.
