Today just observation fly
Using temporary pixhawk 1m bdshot firware and bluejay esc firmware esc rpm showing work

i think pixhawk 1m bdshot throttle based notch on good result but 1mb firmware
When using the BDSHOT firmware you can set
INS_HNTCH_MODE,3
Now just go and run Autotune
On which valvu will autotune get good result AUTOTUNE_AGGR ?
Pixhawk 1m bdshot good for me but less features
Can i go custom firmware builders adding more
features in pixhawk 1m bdshot firmware ?
In features copter fw new update release So do I have to rebuild the firmware?
You can use 1M but it is not advisable.
Of course you can use custom firmware build server.
Yes, on every new FW release you need to use the custom firmware build server again.
Got below fft graph on my new Quadcopter with 26 inch prop.
Use the Filter Review Tool and always use a linear scale.
Filter Review
Select the the linear scale option before you load the log file, then it will make a bit more sense.
Or better still, use the new web-based tool:
26 inch props should have a noise peak around 35 Hz , approximately.
There must be something in your log it doesnt like. You will have to use the MissionPlanner FFT graphs for now, but ensure you have these settings for future flights
INS_LOG_BAT_MASK,1
INS_LOG_BAT_OPT,4
LOG_BITMASK,180222
LOG_REPLAY,0
I have done that and started auto tuning my drone, the aggressiveness was 0.05. But it crashed.
Then again repaired it and trying to manually tune the craft.
@xfacta @dkemxr can you help me with this.
I am attaching a bin file with this link WeTransfer - Send Large Files & Share Photos Online - Up to 2GB Free
Kindly help. It was almost again going to crash. Suggest something.
Update to the latest Stable firmware version (V4.4.4) . After doing so make sure EK3 is enabled and EK2 disabled. Then start over with tuning.
Your Firmware is just too old. 4.0.4 is 3 years old, the tool is only 7 months old. It should work fine with 4.4 and newer.
hi everyone.
Just saw the above log. Actually i am also having same problem.
What is happening with me is my propellers are of 30 inch and it flow fine, but not with standing the winds and speed. If possible can you look into it. i am sharing few graphs for your reference.
@xfacta @dkemxr @tridge
Whenever i tried it in loiter speed of around 7-8m/s the same thing happens and lead to crash.
AmitSingh Have you find your solution.
That’s not clear, start a new post and delete the above.
Added new topic, kindly check
I have a question about the throttle based Notch filter tuning on a spreader drone. The wiki mentiones settings for the hoverthrust. How would I set this, when the total take of weight is 50kg, but it looses 20kg during the flight?
INS_HNTCH_FM_RAT
helps with this, by allowing the notch to be scaled down below the FREQ you have set.
Normally we’d use 0.7 but you may need 0.5 or something…
A flight log where this weight change happens would be good to see, and we can use the Filter Review tool to check what works at different stages of flight.
If you have a suitable flight controller, it might even be better to use the in-flight FFT option, but dont jump into trying this before exploring the throttle-based notch filter, and getting a good idea of the range of noise.
just caught my attention, is there such motor order supported by Arducopter? 3 and 4 opposite. interesting, wiring correct but label wrongly?
