Pixhawk 2.4.8 RadioLink Time Out

Did you want ArduPlane? Because you are posting in Copter.
And which version of firmware did you flash, Pixhawk1 or fmuv3?

@dkemxr
Yes it’s my fault
i am working on an arducopter and the firmware was wrong

now it’s right
but my new problem is i can’t armed by radio although i didn’t have an error on data screen

there is any setting should i edited it ?
on radio controll or MP ?

Now you have a very old version of firmware installed and you didn’t answer the question. Pixhawlk1 or Fmuv3? Which did you install? And then we can direct you to the current version to install.

It would be a good idea for you to read thru the Wiki on setting up and configuring a new vehicle or this could be a series of basic questions asked not related to problems to be solved.

@dkemxr

With regard to firmware
it is Fmuv3 (This is recommended on the box)
and the version is 4.0.7
and sorry but i thought the question problem solved

For advice, thank you and apologies for the inconvenience
But I have a graduation project deadline very soon and I need help so I am asking
I apologize anyway

The box is probably wrong because in the HW ID screen it’s only showing 1 IMU and those are supposed to have 2. And you need to update the firmware to the latest Stable version which is V4.3.7 as of today. This is what I suggest you do:
Click on this link Pixhawk 1 V4.3.7 and download the file arducopter.apj.
Then in Mission Planners Install Firmware screen click on “load custom firmware”, choose the file you downloaded, and follow the prompts to flash it.
If you decide to do this then post a screen shot of the HW ID screen again after connecting and we can confirm if it’s correct.

Like I said it’s too bad you bought a Radiolink product.

@dkemxr
i did what you said
the first time it started to install then stoped and told me down the line "No Response from board "

then i tried again and i had this tab

What does it say at the top of the screen. The other screen shot you posted it says V4.0.7. Something doesn’t make sense.

@dkemxr
in the top now it is v4.3.7
I didn’t know it was on top
and when i tried to upload i didn’t see “done”

OK and the HW ID screen shot?

@dkemxr
this is the HW ID screen

OK, I think you are good now.
Back to arming, how are you trying to arm it? Do you have a safety switch installed? If so have you pressed it? You need to look at the messages screen below the HUD for errors.

This is a poor reason to not read the documentation.

@dkemxr
the try arming by moving the throttle stick to down and right

i have a save switch but i disable it by some parameters (this was a device)

most of my information of quad is from ardupilot web , but maybe yes , i Must read more

Then as I said look at the messages screen/tab below the HUD for why it’s not arming.

@dkemxr
what should i look in this tab ?

There is no evidence there you are trying to arm.
Did you do a Radio Calibration? Setup>Mandatory Hardware>Radio Calibration.
Are the correct channels showing movement when you move the radio sticks?

@dkemxr
yes i did it
and in Radio Calibration yes all the channels show the correct move when i move the sticks

Post the parameter file from Config>Full Parameter List

@dkemxr
thanks for your time
Parameter List.param (16.0 KB)

Enable all the arming checks. ARMING_CHECK,1

@dkemxr
if i do that
I will face new problems that don’t concern me

now I just want to fly by the radio without any other pieces or features
