🛩️ EFXtra - INAV build and maiden 

You think one can put the ET micro vector in the same space? I have seen you do it with the mpx dogfighter ;) I'm soon about to jump off the fence and buy the efxtra.. but doing research for now.. Ps. love your channel!

Gian Luca Mazza i got about 6 mins on a 2200 4s graphene. Which is par for the course for this plane. Was great fun. But had an untimely end on a bad launch. Which caused bigger problems down the line. Of only it was epp.. .

Ok, clear! Tk a lot..and have good fun,bye.

FPV Daniele Yeah you could use the same hardware in a flying wing. Like you said, you'd just use 2 servos instead of 4. In inav use one of the wing presets instead of the airplane preset. And yes, GPS, Rx and buzzer all run off the 5v pads on the board

Robin Bayer 3 of the UARTS are dedicated pads on the board, 1 UART is for sbus, and the 5th UART is accessed through the ribbon cable plug. So in theory you can access all 5, although practically on this particular build only 3 could be used.

Uhh... should have a deeper look first. Sorry for stupid question. The answer can be found here github.com/iNavFlight/inav/blob/master/docs/Board%20-%20MatekF405.md#flying-wing - I think the only 'bug' is the schema in the configurator itself.

Change in iNav! S5 no longer used for servos with Matek 405: github.com/iNavFlight/inav/pull/3224

This wasn't actually my plane, it was my friend's, I just helped with the build. He had it for a while but ended up selling it to a friend who then converted it to run 6s 😂

If you can make it fit, then yeah don't see why not

@@gizfpv Thanks, its a 20x20 FC also, so should be fine and maybe give me a bit of future proofing. Planning on doing a pan and tilt headtracked DJI version, probably on 3S. I'll get some videos up if it all works out ok. Cheers.

Hmm that sounds odd. Not really sure what to suggest. Have you tried another servo? To rule out the current one possibly being faulty?

@@gizfpv thanks for the quick reply and advice. I've tested the servo (with a servo tester and plug it a working channel) it's working fine. I then soldered another servo plug to pad s6 and hook up 5v and ground and assigned to Inav to yaw etc. But again didn't work 🤔 It's seem pad s5 & s6 are mapping but not working. I double checked my Radio mapping, all good, Inav see yaw movements, tested S5 and S6 plugs with a multi meter, power is at the end of the plugs. Right now I'm a bit baffled, and seem to be going around in circles - lol 🥴 I am considering using a servo slipter on the Alierons, putting them both on S3 and using S4 for rudder instead of S5. Not sure if that will work with Inav mixing? this is only my second build with Inav, previous build was a AR900 wing.

Can I ask what firmware version you flashed to the board.

Sorry to keep posting here, made some progress, seems the S5 pad on FC is now used for the LED signal wire in the lastest firmware for the MATEKF405. S6 pad is for servo. www.mateksys.com/?portfolio=f405-std#tab-id-6

James Donahue Did you get it working?

actually YES .... YEAH !!!! good news i used a different Rx, ( S6R ) cuz the X4r-sb for some reason the rudder channel was pulsing the servo violently !!!!! & BAD news (for me anyway) is i took out the "INAV set up and went regular.... but now that its working i may change it back some day...... another dumb question for you..... is there anything special to do when you take a receiver out of a drone and bind it to a different Plane ????

I don't think so? The receiver doesn't know what aircraft it's in, all it knows (and needs to know) is which transmitter its bound too

well thanks again for some good help..... all is running good and gonna do a maiden flight here in a couple of days.......

Neil Agravante I'm not sure you can add a barometer, but you don't need one. You can get good altitude information from the GPS unit

Thanks for responding. I actually just bought one from amazon last night. I’ll do a before and after test to see the difference, if any.

On the Omnibus F3 you can enable pwm 5+6 if you use a UART to connect your rx rather than use the sbus pin. Connect your sbus rx to either RX1 or RX2 and disable any functions on uart3, and then uart 3 will default to pwm output and can be used for servos

Thx! i will try! Do you think pwm 7 and 8 might also work then?

Henning M No, unfortunately pwm 7 and 8 cannot be accessed :(

Stefano Pozzato we used the hglrc m8n that hobby rc sell.

palankaizs On the OSD setup pase there is a button to upload fonts. Click that and then chose either 'large' or 'bold'

Thanks, I will try it but I though that I tried everything there. Just to be sure, You mean the OSD setup in the inav configurator?

palankaizs yep, the osd setup page on inav. The fonts button is on the lower right of the screen. Atter you select a font be sure to click upload

Thanks!

James Donahue Assuming you have the correct Rx type selected on inav (sbus), it might be due to the R-XSR outputting a inverted sbus signal. You could try either using the CLI code serialrx_inverted=on/off, or you can use the uninverted SBUS pad on the R-XSR. Both of those methods are worth a try

Thank you Soooooo much for responding. i didnt think of that.. i will try it ... dumb question for ya !!!! the EFXtra came with a y connector on the ailerons !!! i unpluged it and went with the pin set up you did !!!! AND... does the channel mapping matter in the TX ie. RETA or AETR etc.....cuz in INAV the mapping only show AETR at the top.... but no 1234 after, like it always did... is this norm ?????

James Donahue All that matters is that the channel map on inav matches the channel map on your radio. On inav it should appear as taer5678 or aetr5678 etc

the only thing that comes up on my receiver tab at the top is the mapping... no numbers 1234 or 5678...... i have the mapping matched Tx and Rx to AETR..... but im not getting the numbers !!!!!!! WTH

James Donahue Huh, ok, that's weird. That probably means either the port has been set incorrectly or the Rx type is incorrect. Have you defo assigned a port?
