Matek F765-WING/ Inav idk HELP!

[TinkerJoe]

I'm Using the Matek F765 with Spektrum Dx6e transmitter and SPM4648 reviver. I am new to fixedwing and INAV but very familiar with quadcopter's and Beta flight. This will be my 2nd FT build. I did the FT A-10 With tons of mods stay tuned for another thread on that. I did that with the traditional receiver transmitter flight test C pac kit. I am currently trying to build FT Corsaorair with the Matek F765 flight controller with fully integrated FPV and OSD and all the gee whiz stuff that is standard on FPV quadcopter's.
My Issue.
- I cannot get my motor to spin despite all of my pre arm settings in Inav all being green. At this point I am not running GPS or airspeed sensors it is just a bare bones flight controller/ reciver. I do t even have my VTX conected yet. I've watched every Matek tutorial I can find on YouTube and by all accounts I should be good to go. But still no go Juice. I'm suck AF. My serois all work, My Transmitter is showing up just fine in INAV. Help this shuld be such an easy set up but........

If I remember correctly, there is a flag that needs to be toggled in the configurator that allows the motors to spin when armed. I use ArduPilot with my Matek boards, so I don't remember exactly. I'm digging for one of my boards that doesn't support Ardu to check the configurator.

Nevermind, you have it checked already. It is at the top of the Outputs page. "Enable motor and servo output".

Can you grab a screenshot of your mixer tab?

FYI, You need to unhook the red wire from the ESC/BEC connector. The Matek board has it's own BECs, and you should never tie multiple BECs together on the same bus. I would also use S1 for your primary motor. If you don't have a 2nd motor, remove it from the mixer. (if it is there)

So I did all the things you said to do and nothing. I changed out my esc because I had one on hand, nothing. Also here's the Mixer tab. Do you think it could be something with the spectrum transmitter? I am pretty new to spectrum in general but everything seems to be working like it does in Beta flight with a drone.

Does the motor spin when you test it on the Outputs tab?

Does the motor spin when you test it on the Outputs tab?

Yes, but not until about 18% if that means anything.

if you want the motor to spin up on the bench, you have to enable this:

that can be normal, I was bench testing a bunch of motors and most of them didn't spin up until at least 1100ms, there is a minimum for most setups for it to spin up.

you also have 'stop motors on low throttle' checked

I have and they do. When I disconnect from Inav and just go straight off the transmitter I can't get the motor to spin

 

[JasonK]

on your modes tab, your going to want arm to cover the are for angle mode also as your doing double duty with that channel, else you won't be armed when in angle mode (so it won't arm there).

 

[JasonK]

and your channels all respond correctly on the receiver tab?

the 'arm' sequence is to set your throttle to zero, switch armed on, then throttle up.

You should probably calibrate the ESC.

what is "nav_extra_arming_safety" set to? If you don't have a GPS, it should be set off.

 

[JasonK]

I never had to calibrate my ESC when using D-Shot, I think the protocol is different and avoids that issue.

No calibration in dshot because the ESC is being passed a number so no conversion needed. In regular ESCs the signal is the same as to your servos, analogue, so you need to train the ESC what is the lowest and highest signal that is going to be sent, and that's calibration.

It was set ot ON, turned it OFF. No change

Calibrated my ESC, Helped the throttle response for sure! but didn't fix my arming issue.

 

[TinkerJoe]

CLI DUMP for you guys. Let me know, Thanks

 

[CarolineTyler]

You have nav_extra_arming_safety in its default setting ON.
You will not be able to arm the motor until you have a GPS lock

 

[JasonK]

Looks like you have your ESC protocol set to Standard, I would change that to D-shot unless your ESC doesn't support it. You will get better FC to ESC interactions.

Do you have FPV wired up to the FC? can you check your googles to see what warnings are showing up? might tell you why it isn't enabling.

I'll set up my VTX tonight and see if it tells me anything
