wow!

At the time of buying I assume they had a deal on the "add these extras and save" . Which is why you have the extra frame kit, this is what happened to me as well lol

"That's brilliant, so that worked!" - as the drone smashes into the ground. 😀 Seriously, great video Andy, setting up RealFlight is a pain, this will help a lot of people. [Make sure to watch part 2!!!]

We can't hear you talking while the sim is running Andy! You know you can press "M" to mute the sound in RealFlight?

I want to implement path planning in this what can i fo

Getting back into FPV after a little while out, Pavo20pro on way, about to put it all together this week.... I'm used to betaflight, So i'm curious.... Is this for anyone or a specific purpose firmware?

I was complaining about the gps pads but my got the nano surgery and soldering you had to do to get I2C to work.... Well done. I hope betafpv learn from there design decision and layout the board better next time.

I have a qwiktune question. In a tilt rotor vtol. I hit the default maximum yaw values Allowed in qwiktune. What is a good max to allow the pids to reach to achieve oscillation? I have the feedforward set correctly.

Great job Andy 👍

I guess my message asking for help was either not recorded or deleted , but it’s ok by now I got used being ignored , great videos , I will watch more and again !

Thanks for doing this. Riz from Discourse on Pavo Pico topic.

Thanks for explaining the reason for the triple notch; do you happen to have a reference on this topic? Paper or presentation or anything?

I think that this is indirectly solving a control architecture problem. In practice it would seem the FPV pilot would like to increase speed, but using throttle alone will result in all four motors speeding up equally. So thrust is normal to body. If the desire is to have increased thrust in the direction of travel, why not have a FPV mode that uses a coordinate frame with one axis along the velocity vector and two orthogonal to it. I think experienced FPV pilots manually must do this, and I am not sure this entirely addresses the nod issue. Funny thing is a lot of my past work involved relating air vehicle (type unspecified...) body frame acceleration to higher level (outer loop) guidance objectives. This ad hoc approach would have been easier with a different autopilot architecture. It feels like something of that nature is going on here. I usually think what four variables are you really trying to control as you have four degrees of freedom to do this here (four motors) and develop the control architecture accordingly. I realize you don't have a white sheet though.

You must be used to more agile frames (FPV) to rock the fram like that. Nice handling.

Excellent discussion Andy

How and what do I do to set the rx to tx on my radiomaster 16s for the video? Thanks for all your awesome build video's, I often use them for my builds. So much great info. Think i have that fixed. Now my transmitter keeps showing vtx power level constantly am using yapuu script. How do I fix that problem. Using crossfire tx and vtx.

Hi Andy. I purchased the x500V2 exactly two years ago and was inspired to try using RPM feedback now after watching your video. I updated to the latest 4.5.7 with Pixhawk6C-bdshot and tried my own parameter values as well as mission planner presaved. Still, I can not get the serial connection to work in BLHeli. I can also generally not connect with ESC configurator and usually get the port is already in use warning. Once or so I did get a connection with the ESC configurator, but the read function did not produce anything and there was no flash option. Do you think it is possible that I have older ESC that do not support bdshot?

Andy, thanks for posting this. It is not clear to me what the hang up with RC5. Were you experiencing a low-power limit with ELRS as a result of not having arm on the is switch? And what if I just rely on arming by pulling throttle back and to right. Do I really need to rely on a mechanical switch for arm/disarm. I don't like this because of the possibility of accidental disarm during flight. Please advise if you have the time - do I need to arm with RC5 on ELRS?

Im tunning a t2 vtol. How did you fix qautotune to tune yaw? Im on 4.5.7.

Thank you for the video. It was very helpful. Can you dive a little more into where the ardupilot functions can be found as you mentioned some of the definitions are ardupilot and how to basically edit the ardupilot firmware in general steps for my custom designed board. It will be very helpful. Thank you again for this wonderful discussion,

Andy, thanks for providing your params file. I will compare it to an unmodified one to see what tuning you had. My setup is slightly different so I can't use it wholesale, but look forward to seeing the effect of using your updated PID settings.

What voltage divider info did you use for the pdb?

Hi Andy. I managed to connect everything and armed and all ground test seems to be fine. I tried to run engines on higher setting and see how vehicle behave. It is not stable on high settings and has tandency to fly backwords as i noticed on just short hop in in the air. Let me ask you props marked with yellow sticker are counter clockwise rotating pros and other two without stickers are normal clockwise rotation. I could not find that detail anywhere. Thank You.

Andy, I am still working my way through this video. I am building a holybro x650 and orange cube. Great to hear you finished dshot for cubepilot. I would really like to use bdshot for the reasons you mention. It seems there is conflicting information online whether this can be done on the main outputs. I recall reading the orange cube hardware would not permit bidirectional traffic on the main lines, and hence bdshot was not possible? You are demonstrating it in this on the pixhawk 6 pro video, so it appears you have worked through everything. Is this capability also on the orange cube?

How many amps at hover? 6s battery?

Are you not worried about the esc's overheating without heatsinks mounted in the body of the drone?

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

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

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?
