I’m new to building quadcopters and assembled a Holybro S500 kit with PixHawk 4. Everything worked straight forward. But my maiden flight yesterday was no success.
The copter just wobbled on the ground and did not lift off. I started in “stabilized” mode.
So the main thing that was not really clear to me, was the motor configuration. I followed the guide here an my wiring looks like in this diagram:
Unfortunately, you can’t spin up motors in Qgroundcontrol with px4 1.10.1, there is a bug. So I decided to flash ArduPilot. And there motors behaived very wired. I figured out how to wire up the right order with ArduPilot.
Then I decided to flash the px4 Mainbaranch. Motor spinning works there. Again, the order was conpletely wired. I did build it back (Motor#1 to Output#1, Motor#2 to Output#2…). Now it looks again like in this diagram, and I found this pic in the Doc, where wiring looks similar to mine:
Mhh, looks like I was right in the first time. And I flashed back to the stable version of px4. ArduPilot an px4 seem to have different motor mappings.
Also, my motors are spinning to the right direction.
So what could be the problem?
Is my motor setup OK?
Maybe a smaller Lipo (actual: S4-5500mAh, about 500Gramm)?
A better ground to liftoff (started on a plown field)?
First trys with AutoLiftOff and AutoLand?
Lot of questions. Thank you for your help
