Hello. Just wondering if I could get some advice.Since day one, my hex has had a problem with uncommanded roll/pitch. I think (its hard to tell with the control issues) I have gotten my rate pids…Continue
"I'm curious about this as well.. Seems like you can augment steering with a simple gyro in a normal RC vehicle (for drifting etc.) So how about with APM? Also, what about adding some rotery encoders for abs or traction control? Deffinately some…"

Just a quick question. What does the "preflight_level" command under the actions tab in the flight data page of mission planner do with the 2.9.1 release? does it only re calibrate the gyros? I was under the…"
"That's a good question and would be worth asking in the '2.9 release' thread or the MP thread.
The original Level command was removed and replaced by the calibrate command because doing a level would screw up the accelerometer…"
"Ok, that was what I was thinking regarding the accelerometer calibration.
It's actually "Pre Flight Calibration". I thought the word "sensor" was in the name, I wasn't by my computer when I wrote that reply.…"
"You have lost me with the 'Pre Flight Sensor Calibration' ??
Where is this function?
The Accelerometer calibration has to be done and that is all the levelling it needs.
And yes, it needs to be done on all sides but not redone all the…"
"I have never used the Level command in the configurations tab other than when I initially calibrated my accelerometer. All other times I have had to level the copter I either used the "Pre flight sensor calibration" or just…"
"Just a question on your procedure for level.
Are you using the CLI level or the Level command in the configurations tab?
Apparently the CLI level does not do good things with 2.9 and the Accelerometer calibration should be used in the Level…"
"Just an update... I calibrated the ESCs individually and it helped a little. I was able to completely remove the backwards drift however the uncommanded roll is still present. No amount of trim corrects this. While…"
"Does it always roll/pitch in the same direction regardless of wind or heading? I was having the same issue and realized that one of the motor screws was in the wrong hole about 2 cm off. If this is the issue, you will be able to see a…"
Thanks for the reply. I will try the manual ESC calibration as I used the auto cal method. I was lazy.
I guess it's unclear to me as to how or when arducopter calibrates its sensors. From my understanding, the…"
I used to have very similar issues with my first quad. Here is what I did to address it:
- I run the manual esc configuration per the wiki as I feel I get better results
- when attaching the battery to your Copter, be sure that it is…"
