I can't get the engines running even though the prearm checks were successful

My problem:

This is my first drone project so far so I’m kind of newbie.
I cant get the motors running. I tried almost every possible solution the last 2 weeks.
Now I’m at the end of my knowledge.
I want to control my drone via Wlan for now (later I want to connect a USB Modem).
The RC is a Xbox 360 Controller connected to my Laptop.
The communication is working. I configured the Joystick in Mission Planner and finished all the Prearm checks.
I had some trouble with the callibrating of my ESCs via Mission Planner. I ended up calibrating them manually with a little python program one by one.
I can arm the drone and I also receive signal. However when I try to rise the throttle nothing happens
I get no failure message and the motors also do nothing.

I’m really hope someone here may help me.

If I missed some informations about my setup let me know.
I attached some pictures of the things I think where the problem could be.

sorry for my bad english :wink:

thanks a lot in advance

My setup:
Arducopter 3.5
Navio2/Raspberry Pi 3b+
4x Emax RS2205 S 2300kv Motors
Littlebee 30A ESCs

How do you put the throttle all the way down with the xbox 360 controller? Do the ESCs get a low throttle (around or below 1000us for most ESCs) signal on startup? Otherwise the ESCs will not arm themselves and the motors will not run.

Hello,

Thank you for your reply.
I would love to test this out but my laptop got broken today -.-
I have to send it to the customers support first.

I tried to change my GCS to my desktop PC but I can’t get the Navio to communicate with my Desktop

“Mavlink Connecting…”

I try to get this working and will test your suggestion immidiatly afterwards.

Not my week after all…

Hi @Cryxos,

Did you have a chance to fix your PC and make a test?

Hello,

not yet unfortunately.
I cant connect the pi to Mission Planner

I don’t no why the connection with my desktop PC won’t work. I just changed the IP.

The Notebook will need some time unfortunately.

Hi @Cryxos

Please, doublecheck your PC IP.
After that, in /etc/default/arducoptercheck that you’ve set the right IP.

Can you share a screenshot with ipconfig command output?
