ArduPlane Plane 4.5

Hello,
I’m new to mission Planner and Ardupilot.
Curently trying to activate servos and having Issues with reading PWM Signal, I tried updateing Firmware recallibrate everything. I’m getting good signal with reciever and contorller, but still nothing. can anyone help me with that.

P.S. I did plug BEC but still nothing I tried to instal QGC Frimware also and It worked perfectly I actevatied servos motor esc etc.
I also tried and installed Mission Planner firmware on Speedybee f405 wing mini with the same settings and it also worked perfectly

“Prearm: Waiting for RC”

Is the radio connected?

8

It was not connected at that moment

9

No.
Google works.
Bing works.
DuckDuckGo works.

RC connection is not required for getting PWM output.

11

Agreed. I was just wondering how the PWM were being tested is all.

12

How you check the PWM output?
Is the servo power rail of the pixhawk 6x powered?

13

yes I use external BEC to power pixhawk 6x servos

I’m moving sticks on my controller and trying to get some resopnse from servos (movment )

14

moving stick on your Controller means that you have directly a stick connected to your PC / Mission Planner? Or you mean the sticks on your RC Transmitter? In last case see @Allister comment.
At your test was the FC armed or disarmed as shown?
Can you provide a log file of your test with log enabled also when disarmed?

But there is one issue left it my pitotube I can not activate it
am using CUAV ms5525 digital airspeed v1.7 and it is connect to by pixhawk board in I2C port
can anybody tell me more how to activate it

First of all, look at all the setup steps described here:
https://ardupilot.org/plane/docs/airspeed.html
If it still doesn’t work, we can go on from there.

Edit: in addition to the link above, I would also check cable length and shielding. I2C cables should be as short as possible, twisted pairs or maybe even with metal shielding to counteract outside interference.
