I did the mission planner motor test to confirm rotation, but I will argue that the motor test will not show how the autopilot reacts to the body being tilted.
Also a motor test will not show how the UAV reacts to RC inputs.
Where are you getting this 3kg number from? I am curious because I have only been able to find hear say from past forum posts on MTOW of a X6 with Tarot 5008 KV:340 motors.
The tests you made also do not reliably do what you want and expect them to. Closed loops do not operate reliably in a open loop configuration
I have not heard of this before. I will investigate and see if this meets my needs.
Ok trying to make sure we are on the same page here.
I did use the motor test to verify motor order and rotation.
I used stabilize mode for my “tilt test” where I raised the throttle to about 20% and lifted one side of the drone to simulate a wind gust. I then monitored the autopilot’s response (visually through the motors rotating faster or slower, and by real time graphing the signal out to the motors) by changing motor speeds in attempt to level the craft.
I used stabilize mode for my “RC test” where I raised the throttle to about 20% and used the RC to adjust the roll and pitch.

Which part of this is my logic flawed?

And notice my use of the word “reliable”

Hmm so if I understand correctly, motor test will send unmodified thrust values to the motors you want, without the autopilot attempting to alter it due to the UAVs attitude.
So this method would be good for testing motor assignment and rotation. Would this also be a good way to check that I properly calibrated the ESCs?
I probably didn’t communicate this properly but I do understand that by doing my tilt and RC test, that its not perfect because the props are not on so the response the autopilot is expecting is not there. The part that I’m confused on is, did you mean there is more I can test with the motor test function that I’m not seeing?
Also, I really appreciate you input on this issue.
Yes, that is correct.
yes.
Just use “mission planner Motor test” in the way that it is documented. And that is all you need.
And of course you need New ArduPilot methodic configurator GUI
No! This is bad advice when the user hasn’t reported any successful flights yet.
Do not try Loiter until the drone is flying properly in Stabilize and AltHold. Basically stick to the Methodic Tuning Guide.

I would re-re-check the correct turning orientation of the props ( not talking about being upside down but that there are props made to turn left and others to turn right.
I recently setup a quad using Castle ESCs (different from yours) but also had the vehicle flip over. The fix was to configure the ESCs for “multirotor” mode using the Castle software. Perhaps check if your ESCs have that option.
Check the motor outputs are the correct order. I had the same problem with my Tarot 650 frame. The pixhawk outputs are different to the tarot. Hope this helps.
My rig is tarot 650 frame with dji 800 motors, 15 " props and pixhawk 6x
Agreed, I don’t plan on using any position assist modes until I can take off in stabilize.

Will do, I currently have the props off but will definitely recheck them when I put them back on.

Hmm I will check this. I’m using the DMR 30/40, what kind are you using?
Yeah I’ve used the mission planner motor test to verify motor assignment and everything is wired correctly.
I’m using Phoenix Edge Lite 50. I haven’t used the DMR 30/40 before but it looks like you can program them with the Castle software. For my setup, the ESCs defaulted to “airplane” mode which produced a signal at a lower frequency than required for multirotors. I don’t know if the DMRs are the same - but it would be a quick check.
Sorry @steve220 but that goes against all recommendations and against common sense.
Please do continue to do that yourself, but do not recommend that to others. You are endangering their property.
