Requesting Help Calibrating SimonK 30A Esc on a PixHawk Board

Greetings Marty,
So yes you are right < and my apologies > - it is “not” tilting right over < immediately>
If I increase the thrust < about 30 to 35 % ) it will lift off - but it is extremely unstable.

What I have not tried it as soon as I get it airborne - about 1o to 12 feet - put it in Altitude Hold.
Do you think that is a good idea ?
And if I can get it to Altitude Hold - I try and use the pitch and roll to control ( to achieve Hover )
Last time I tried this - it was extremely reactive and I lost control.

Now watching Randy’s YouTube on Tuning - he say to configure a SaveTrim switch on the Radio controller. I was not able to do so.
I am attaching three screen captures - please let me know if you see something glaring which is not correct.

I am afraid I cannot really take a video - since I do not have someone to hold a camera.

Again thank you for helping me.
Rahul.

Thank you Rahul,I will take a look at the settings on my 450 later and see how they compare and report back to you

MOT_SPIN_ARM should be set to something like 0.10 or just under - whatever allows the motors to spin as slow as possible but reliably.

Don’t worry about doing the Save Trim thing.

Provide a link to the .bin log from when you had it flying, and we can provide you much more info.

Thank you in advance to both of you Marty and Shawn.

#2: I have not yet got an opportunity to fly ( more like scared to crash ). But attaching a Bin file - this is the current Bin file (prior to flight ) .
I am not sure if you can find some settings I should change before the flight.

Also including a link to the log file: Hopefully you are able to access it.

Any feedback is very much appreciated.

Rahul - I am facing the same problem as you are. I connected to Mission planner and did all calibrations. I am getting stuck in ESC calibration. I understand your calibration worked by individually calibrating each ESC, but in my case i have already soldered my ESCs to the board. Did you buy new ESCs after the first calibration failed? Would love to know
