- Howdy, in this part you're going to get to meet the Omnibus F4 V2 flight control board goo.gl/ONfVAY and in "Plain English" learn what pins you need to be aware of to connect up iNav for a flying Wing. More details below, Press SHOW MORE to see them, Matt
F4 Flight Controller (V2 with OSD)
-------------
This is the board that is being discussed in this episode goo.gl/ONfVAY
This is the V2 board that has a current sensor onboard so you're able to see the amount of current being used and the pack voltage more easily.
NEO-M8N GPS
-------------
And this is the GPS unit we'll be connecting to the FC board goo.gl/GIwe5F
Note: Banggood may change the specifications at anytime, the pins are correct for me at the time of publishing the video, however double check your board before attaching anything to it, the labels should be printed on the bottom of the flight control board.

Nicely explained Matt.. You're making iNAV way less daunting for the masses.
Howdy Skyris, thanks. I know the series will be longer, but I'm doing my best to assume as little as possible, thus chances of a successful maiden is much. much higher, Matt
Absolutely helped me both understand the basics of fc's and how I'm going to use your recommended board for my nano talon. Thank you so very much
Awesome 🙂🙂
Hello Matt, first of all, sorry, my English is Google, as always an excellent video, you are the reference when setting up inav, at least for me, very clear and without leaving any aspect without clarifying.
Of course I've seen all inav configuration videos with f4 omnibus, I've already asked you a question for a cc3d with inav, all resolved, now I'm setting up an f4 v2 for a sky shadow wing that I'm running out of, the thing is I want Feed the servos with a bec, and I only need the signal of the plate, I have seen that there is a connector of 6 pin's JST SH 1mm by the bottom part of the plate, next to the pwm connectors, just below the connector Where it connects the gps, which has the outputs pwm (1,2,4,3, 5+ and gnd), but it does not work, if I give current with the bec to the servants, and they go crazy, they start spinning Without stopping, I clarify that all this is because I do not like soldering :-), do you know if you have to configure some output or something in inav to use the connector instead of the normal outputs pwm? What could be failing? What can I be wrong about?
Thank you, a greeting and forgive the inconvenience.
hola matt, primero que nada perdon mi ingles es el de google, como siempre un video excelente, eres la referencia a la hora de configurar inav, por lo menos para mí, muy claro y sin dejar ningún aspecto sin aclarar.
Por supuesto he visto todos los videos de configuración de inav con omnibus f4, ya te he hecho alguna pregunta para una cc3d con inav, todo resuelto , ahora estoy configurando una f4 v2 para un ala sky shadow que estoy acabando, la cuestión es que quiero alimentar los servos con un bec, y solo necesito la señal de la placa, he visto que hay un conector de 6 pin´s JST SH 1mm por la parte de inferior de la placa, al lado de los conectores pwm, justo debajo del conector donde se conecta el gps, que tiene las salidas pwm (1,2,4,3, 5+ y gnd), pero no me funciona, si le doy corriente con el bec a los servos, y se vuelven locos, empiezan a girar sin parar, te aclaro que todo esto es porque no me gusta soldar :-), ¿sabes si hay que configurar alguna salida o algo en inav para utilizar el conector en lugar de las salidas normales pwm? ¿Qué puede estar fallando? ¿En qué me puedo estar equivocando?
Gracias, un saludo y perdona las molestias.
Thank you very much! that was a configuration problem. Everything is OK!
Good show.No idea why my board worked fine then it crapped out only showing 1.78v but works fine with usb power.Never had this happen before got 2 others working great.
Thank you Matt for your great videos.
I have the Omnibus F4 V3 (i.e. no current sensor) and am setting it up for the Nano Talon. My board is powered by VBAT and I removed the 5volt pin from the ESC lead as you suggested. Throttle was fine, but none of my servos worked. Digging through various forums, I found out that I required either an external BEC or the ESC-BEC. For some reason, the on board BEC is not powering the servos. Perhaps there is a jumper or software configuration to make this work.
I've also found out that the Omnibus F4 V3, and possibly other versions, use a triple diode with inputs from LDO, ESC-BEC or External BEC, all going to the +5 volt rail. So theoretically, there should be no smoke as long as none of the inputs exceed the maximum VCC that board can handle.
Yet again Matt provides an excellent guide! Really appreciate it !
Thanks Jason 😀
You are an absolute god send. Thank you so much for the video!
you are awesome, you have covered the most features
Matt, I am new to rc plane fpv installation. Your lecture on the flight controller setup was great. I have a question. The plane that I am going to setup has 2 front brushless motors and 1 more brushless motor at the plane back section for vertical lift powering. The plane has 2 airrons and 1 elevator. The questions is Q1 - For PWM connection where to connect the 3rd motor?. Q2 - battery power from flight controller to 3 ESCs. How to setup connection to 3 ESCs?. Appreciate if you could assist me in this area that I do not know. Thank you in advance.. from Abrams King.
Thats good info. I'm a race quadcopter builder . This is my 🍒 build of my first wing. Lol. All over quad building but a baby when it comes to fixed wing. Thanks God bless
Howdy Craig, happy days fella!
Bloody great mate. Much needed video. Thx heaps
Brilliant video Matt keep them coming
Thanks Hris. Matt
Hi. Great video, congratulations. Question . What is the voltage and current scale that you use in INAV for the Omnibus F4 PRO V2?
Hi Matt....I'm really enjoying the channel.
I git stuck right here. I have a V3 (not your V2) where I have used two of the three available UART ports. One for smart port and the other for the serial RX. What I have now is a RX3/SDA and TX3/SCL remaining on the FC board. I'm assuming, if you can confirm, I'll be able to set up the GPS but not the magnetometer. Is that correct?
If anyone else watching Matt's channel can shed light on this one, it would be appreciated.
Thanks!!!
Howdy Chris, just progress to the GPS episode. A compass is not needed for fixed wing models. Hope that helps Chris, Matt
I am running INAV 2.0.0 on omnibus f4 pro v2. FC is powered by 5V from my pdb bec. (J12 5V on FC)
How can I connect LEDs from the FC? (J16, J17?)
I'm sure you are aware, but I haven't been able to find it here yet ... The Video In/Out header voltage can be set to either VBat or 5vdc by selecting the RAM voltage desired. They are set by a jumper on the v1 card and a solder jumper on the backside for this card. It makes setting up the VTX and Cam very easy with a single servo connector each. Cheers ... dave
Hi Dave, there is a reason why I don't cover that in this series, the less current being drawn through the board, the better. I would strongly suggest that you power your FPV camera and vTx from the main power leads or a separate BEC as shown in the later part of this series, Matt
Point well taken and thanks ...
Bardzo dobry materiał polecam, i dziękuję prowadzącemu.
Hi Matt. Thanks for doing this vid. I'm a quad pilot. But want to fpv wings. This video was so helpful. Would love to meet up with u guys as I'm from Bristol to
I expect it's a bit late now, but can you really run four servos, a receiver and GPS and maybe a camera from that board's 5V supply? Fantastic information for budding iNav pilots Matt.:)
Matt, Nice and clear. So Im stuck with trying to get the X4RSB over SBUS to work. Bind all sorted of course,
I'v tried UART 1, 3 and 6 . What am I missing to get SBUS working ?
One of the best video so well explained a million thanks from Canada
Thanks Roger 😀
I know this is old, but I started a project wing following this video a couple years ago but stopped. I have all the parts and the wing, except the FC which is no longer available. Can you recommend an inexpensive FC similar to this one? Thanks and great videos!
Great video! I really love it!
Just ordered the C1 Chaser and Omnibus F4 w/ OSD. I wonder what is the name of the 6 pin connector that is used for connecting GPS. I have a few GPS units but I'd like to create a connector specifically for the F4 with magnetometer (just like the port allows). Any idea where to buy it? Preferably pins to make a connector rather a ready-made connector with wires for soldering. Thanks!
Howdy Matthias, yes. It's a 6 pin JST SH 1mm connector, see this video for more info ua-cam.com/video/0MntuqO08ac/v-deo.html Matt
finally getting around to watching your inav series. Great stuff. You still recommend these two parts?
Howdy Nathan, ye F4 V2 boards and defo the GPS units. If the GPS units are out of stock, check on eBay. Hope that helps Nathan, Matt
Hey Matt, your videos have helped me out tremendously. I am using the Omnibus F4 V2.1 Pro on a flying wing. I have most of everything setup except the OSD. I have selected all my OSD screen options and saved them. When looking in my goggles, the battery meter and artificial horizon works fine, but even when my GPS is locked and I can see the number of satellites fixed in INav, I get zero in the OSD? Does the F4 Pro automatically feed the RSSI signal strength to the OSD? And finally, what do I need to do if I place the F4 Pro backwards? Is there a CLI command I need to use?
Mike
Hi Matt, I've installed an Omnibus F4 Pro into an S800 wing but i'm having some problems with it. I tried to power the servos from the board but it was only putting out 1.5volts, but 5volts were going to the RX. I now power the servos from a separate BEC but they are quite twitchy and every now and then the servos move from full one way to full the other before returning to their commanded position. Any ideas where I'm going wrong? Or is it likely to be a faulty board?
ps. love the videos, the iNav tutorials are very helpful
bump
can i simply take 5v + and gnd from PDB and connect to FC BAT+ and gnd? I dont want use current sensor or correct voltage on the display?
Hey Simon, no idea fella Matt
I think I was not clear enough. my esc are soldered to a PDB which is where I want to connect the 3S lipo. My PDB has got 5v BEC. Can I power the omnibus f4 pro v2 from that 5V BEC? (connect them to BAT+ and gnd pads on the flight controller)?
Yes you can, you can even use the direct voltage of the 3s bat, I'd suggest using 12v
Hi Matt, im currently putting this flight controller into a s1100 reptile with your awesome video tutorial, only it's customized with twin edf's and retracts.
Question time, can differential thrust be used with the two esc connections like a rudder, that way i wont need a steerable nose wheel.
Cheers.
Howdy Max, you'll need to see the inav wiki for this as I have never done diff thrust with inav. Matt
Thanks Matt, i will have a look there.
Hi Matt! My Inav install and setup are done....just waiting on the snow and wind to settle a bit for the maiden. I have my servos connected to the PWM pins on the Omnibus f4 v2 and the servos are working as they should. Will I be ok to run the setup like this or should I power the servos from an external bec? I thought I remembered you saying that a vex isn't necessary but some people on the Inav Facebook page are telling me differently.
love these videos man. thank you for making them. my question is... why didn't you power your vtx and cam from the supplied power from the fc?
Howdy fella, thats simple and a fantastic question! Noise and power is the reason.
You can provide better filtering using a larger toroid coil or low pass filter for the FPV system than what the board can provide. Also it's always best to limit the current being drawn over such a small board to the minimum, so removing the vTx and a FPV camera can massively help. Plus most modern FPV cameras and vTx's can take full pack voltages.
Hope that helps, Matt
Hi. Thanks for your videos. I am trying to bild a C1 Chaser with APM 2.8. I thing you are iNav fan.
I would like to ask you how can you explain what you say on minute 7 about to fonts off power supply. As fas as i know parallel power connections on DC are possible without problems. Why you say we must power with only one source'
Thanks
Keep going
Hi Matt and thanks for such helpful and informative videos. Documentation on the Omnibus is almost non existent and having your series to refer to is invaluable. I'm setting up a mini talon at the moment and so need to use PWM 5 & 6, I have a 3.5A BEC from the ESC, would you recommend that I power all of the servos from the BEC and not the board.
Morning, "absolutely" is the short answer 🙂 And I'm glad you've found the series helpful, Matt
Hey Matt, I have a scenario that I hope you can help me with.
I received an Omnibus F4 Pro board yesterday and want to place it in my wing.
The board I had been using was a SPRacing F3 board, so the GPS unit had to be "modified" by removing the connector so that I could connect to UART port.
Now with the Omnibus board, I don't see where I can hook up the GPS Tx and Rx other than that 6 wire molex connector on the board.
So how can I connect my modified GPS to the Omnibus?
Any help would be greatly appreciated.
Also, it's been your series on iNav that brought me to this point. (So it's your fault! :P)
Subbed and looking at all your iNav series videos.
Thanks in advance.
Howdy fella, I'm not sure on the F3 boards. See here s3.amazonaws.com/zcom-media/sites/a0iE000000GWIo4IAH/media/catalog/product/s/p/sp_racing_f3-1.jpg and pick a UART that isn't being used and set the GPS accordingly for it. Try that, Matt
excellent video Matt. thank you.
Thank you! 😀
fantastic matey at 18.36 the picture what are the red pins for are they just hold the wires out for us to see just being nosy i guess
Oh those! They're being used to hold the tray down, so nothing special and I had stuck them at the back out of the way for the video, Matt
Great. I was looking for it.
Hi Matt. Congratulations on another great video.
If I could just say one thing... You don't need to connect to the RSSI pin. Instead you can send RSSI back from your transmitter on a spare channel and tell INAV to interpret it as the RSSI level.
github.com/iNavFlight/inav/blob/master/docs/Rssi.md
Of course, you do need to do a bit of jiggery pokery on the transmitter, but there are posts on the internet showing you how, at least for the taranis and 9xr Pro.
Just to recap: transmitter reads RSSI from receiver, does a bit of maths and then sends it back out on a spare channel. Flight control reads that channel and knows what the RSSI is without any extra wiring.
Howdy Skylark, yes that is possible, IF you don't want to use too many switches and have a Rx that supports telemetry. I could do this with the Hornet wing, however want the 4 extra AUX channels for switches and it only supports 8 channels in D8 mode. Matt
Hi, Thank you very much for the detailed explanation. One Question.
When it comes to connecting the ground from Batery to the FC: As far as i understand it, a relative thin cable should be sufficient since there should be no heavy load running through this one except for what it ineeded by the FC itself as well as servos?
Hey Wolfgang, do not skimp on that step, one of the lads used silly thin wire and hence it went up in flames under load. Matt
This was PERFECT! Thanks
very good video, thanks for making this.
Have you ever explored Betaflight. Rssi is already programmed on channel 16... Thru GUI. Receiver page.. don't have to solder note as long as you activate telemetry via uart port.
Howdy Craig, yes this is the same for iNav, but a L9R does not support telemetry so no RSSI and has to come from the dedicated pin on the L9R receiver, Matt
HI Matt. What about fixed wing using Y cable to drive both ailerons?? Is that possible?? Thanks for all the great info.
Howdy Kevin, I'm not sure thats possible as iNav suggests separate channels for them, Matt
Matt - I see in this video you say to disconnect the ESC BEC wire, but in the trouble shooting video later you say that if the servos don't work, you need to provide the power from a BEC. I'm confused! Please help? Do I use a BEC to the FC board, or not?
See the earlier video, a BEC is needed. Matt
can you use an external current sensor if you where using a PDB with one on it already? I don't like running all that current through the main board like that. May not be an issue for a plane, but a quad it could be, and you would definitely use a PDB for one of those. Also. Can you pull enough power through the FC to power the servos? or should you use an external BEC to power them?
works perfectly fine on a quad, i've had 2 birds with it (albeit on betaflight) and never had an issue with it running 150+ amps
very detailed and helpful thanks! one thing im stuck on, i am using a dsmx (spectrum satalite rx) and been worried about connecting to the spectrum 3 pin port as im told its 5.5v and the receiver (spectrum satalite) is only3.3v.....do i need to adjust from the jumper? thanks in advance!
Hey Vinny, I have no idea on the the Spec sats. However those dedicated sockets should be 3.3V for them. If in doubt, check it with a multi meter, Matt
RagTheNutsOff Thanks again for the fast response! Connected to supplied 3.3v connector on the side...works a treat!👍
Good video Matt👍 it looks as if I'm buying another flight controller🤣🤣
Thanks Roddy!
Hi Matt, if I you were using channel 5 and 6 for an aeroplane, would you still be able to use all the pins in the J10 connector for a GPS? Or are TX6 and RX6 pins shared?
Howdy David, you should still be able to use them, well as faras I know you should be able to use them, Matt
Hi, although the Flight controller you suggest is cheap, it can be faulty. I experienced on my own after ordering from Banggood. I followed all the steps, but the board doesn't work when connected to battery (it works with USB connection). After this down-back, I've made some research and found that it is very common with these CLONE boards to have malfunctions. So it would be nice to say it clearly in the videos. You could also give link for the official board, so people would think twice if saving 20 € is really worth. Said that, I thank you for your videos they are very good, but the hardware you suggest can be crap, you could at least warn about it.
Hello Matthew, the gps unit you linked seems to work only up to 3.6Volts, but you are suggesting to wire it on a 5V pin (the one in the white connector). I would be a little scared.
If you look closely you have 3.3 V power supply from the spektrum satellite connector and one more on the board, but it's just a tiny pad as the rssi one. I surely would prefer your method but it seems wrong. What do You think about? Thank you for great videos!
Howdy, this question has come up numerous times. The GPS will run on 5V, the sockets provided on the unit are for a pixhawk and the pixhawk runs these on 5V. Also I've run the same unit on a Pixhawk and also these boards for numerous flights and not had an issue. I don't even know if they will actually run on 3.3V as I've never tried! Matt
See the GPS port section on this page pixhawk.org/modules/pixhawk Matt
Thank you Sir! Now I know I can wire it up a in a very easier way. It will run on 3.3V because I have it that way on a quadcopter, but 5V is so much easier to find! Thank you again.
Right, I've just stuck a multi meter on the VCC pin on the GPS chip, 2.97V on a 3.3V supply and 2.99V on a 5V supply, the board MUSt have a voltage regulator on it, I suspect thats what the 15ZF chip is :) I'll make a video about this later, Matt
Howdy fella, see here ua-cam.com/video/LFkKcOpFo7k/v-deo.html
Hey Matthew! What a great video on this Omnibus v2. Just one question, right now Im planning using X4R on my S800 but which port on the X4R should I connect to the RSSI pad on the Omnibus V2? Thank you.
Howdy Alif, I only have one X4R and I've never tried feeing in the RSSI from a pad, however google this "x4r rssi pad" and look on the images tab. However frankly speaking I'd push the RSSI down through a PWM channel instead and use that. See here for more details github.com/iNavFlight/inav/blob/master/docs/Rssi.md Matt
Hey Matt! Got it! Thank you for your reply. Have a great day :)
I Matt
I'm changing my Skywalker X6 setup and i will install a Omnibus F4 V2, 4S 5200mAh Multistar, NTM 3548 900 Kv motor, Corona DS339MG servos . My question is if you think it is ok to power servos from the FC or it is a better idea to run them from a separate 5V supply.
Keep the great job!
Howdy Nuno, 100% a separate BEC for the servos wherever possible. It adds a few grams, but hey a model that size won;t notice it compared to that 5200 4S pack :) Matt
Thanks!
Just another question... as i will use a separate BEC, what do you think about an opto ESC? I have some Racerstar MS Series 35A ESC BLHeLi_S OPTO 2-4S around...
Hey Matt, Does that current sensor actually work for you? I have a couple of these boards from BG when I connect the way you do through the current sensor the inductor on the back of the board get extremely hot (not you cant keep your fingers on hot, you get 3rd degree in 1 second flat hot) in seconds and the board has no power. The boards are awesome if I just ignore the current sense pass-through and power pos/gnd as normal.
Hi Andrew, yes it does. It needs to be calibrated, which i assume you've not done hence the question. If using a F4 V2, try setting it at 740 in the configurator, that will get you close. Matt
Just curious as to why you wouldn't utilize a PDB for the build?
HELP! At 7:00 the video says to disconnect the ESC 5v rail.... The flip32 f4 omnibus board I've got says in it's advert that it has a 5v 3a sbec but goes on to say "You will need to power this board via an external BEC as the built in LDO is just used as a voltage protector and cannot be used for a long time, otherwise it will overheat" which leaves me totally confused as to whether it needs the ESC's bec or not.
Morning Seafax, it'll either work or it won't. I cannot comment on that board as it's not either of the ones which I suggested for this series and both of those need an extra BEC to power the servo +5V rail, Matt
just curious Matt, I know it's an obvious question, but i haven't experienced any board other than a cc3d, so I'm just curious what cables do i use to connect my receiver to this board? They don't come with it when you order it do they?
Hi Owen, thats right. For this board you'll need a male to male servo lead, from the receiver to the board and a small JST connector covered in this video ua-cam.com/video/t7dUVNx7S7s/v-deo.html
Great video but I'm still confused about hooking a 3.3 volt GPS upto 5 volts.
(Maybe I'm unlucky and ebay has sold out of 5 volt versions of the M8N GPS)
THX MATT,Very Helpful...
Thanks Mark :)
Matt - there are two F4 brds - - a = OMNIBUS F4 Pro V2 Flight Controller from GearBest £13
b = BF3.2 Omnibus F4 V2.1 Flight Controller from Banggood £26
I have gone for 'a' the cheapest, have you any idea as to the difference and will it work ok in the Falcon...joe
Hi Matt. As I have no experience with flight control boards can you tell me the purpose of the sd card slot and can it be used in this context?
Another very well presented video by the way👍
Howdy Davy, ah ha good question, data logging. It's called a "Black Box" and stores data from the flights in case it's needed by the developer team later. Matt
Matthew Ogborne gotcha. Thanks Matt
I am building a wing
they say to remove the red wire on the servo plug on the speed controller
I'm not getting 5 volts on my servo
this board supposed to have 5 volts for the servo
is there something I'm missing I have to jump
my 5-volt rail is dead for the servos thanks for your help
Hi Frank, see the rest fo the series, the 5V comes from your ESC, Matt
Is this possible to connect to a T-Rex 470 helicopter all that I am interested in is the GPS return to home RSSI functions the rest of it does not concern me. I have my own on-board fbl computer to function the servos and exedra. think you
Hi Scotty, as far as I know helicopters are not supported by INav, Matt
Hi Matt Have a question. I'm planning on running an opto esc. However my camera (runcam split) requires 5v is there a place on the board where I can draw 5v from? Or will I need to get a separate bec to get 5v? Thanks
On second thought I think I may be ok. The first generation of the runcam split only took 5v. The second generation takes 5v to 17v. I will be running 4s in the nano talon so I should be ok running off the pack.
Howdy Michael, yep out of the pack and as little as possible being drawn via the board. Just make sure you have a common ground on your FPV gear, Matt
thanks thanks tanks now i lurning somting !!!!
I can't get OSD working with my F4 v2 board , any suggestions. i am using common ground and if connect both video wires directly camera works however if connect them to FC didn't work.
Morning Ashish, have you uploaded the fonts? See the common mistakes video I did a while back, Matt
Thanks for your reply, I did upload the fonts. when I connect my video wires through FC board I am not getting any video. I did swap the wires just in case i was connecting vin , vout reverse.. however it didn't work.
Hi Matt.
Have you ever got this board to work with Frsky Sbus?
This is the Banggood clone, yes?
Hey Arne, only ever single one that I own with SBUS, both for the BG ones and the eBay clones too, Matt
Wow! Quick answer:-)
I've been at it for a couple of hours now, but I think I'll spare myself and go for a PPM instead. Or order an original.
Thanks for answering, and for a fantastically inspiring channel.
Have not yet finished watching the whole video (slow intermitent internet connection) but want to ssk if the board has a barometer and if it comes with cables for the micro JST connectors.
Howdy Ako'y, I believe it does, but you'll want to disable that as you get the height from the GPS unit. And you'll need a special JST cable that is covered in this video ua-cam.com/video/t7dUVNx7S7s/v-deo.html Matt
Hello, wouldn't an onboard baro be more accurate than GPS for altitude control?
Howdy David, when I used a Baro first time around with iNav, my Teksumo got smashed into the ground 3 times. The GPS is accurate enough, because unlike a quad, a RC plane is typically always going forwards, unlike a quad that has unlimited yaw. I've not used it on any of my builds and it's worked great with just the GPS, Matt
can I powered this board with 4s batt?
because I just bought it, its okay when I plugged the usb cable.
but something goes wrong when I powered the FC with 4s batt.
it turn on about 5 second and gone forever.
back to the question, is it okay to power this FC with 4s batt?
can we use Original Airbot Omnibus F4 Pro V3 Flight controller SD 5V 3A BEC OSD Current Sensor LC Filter
Hi Ashish, it'll work with any iNav compatible board. See their website for the full list. Matt
Hi, I used the omnibus f4v2 with gps (wing model) and even if I have more than 10 satellites, on the screen I see that the compass orientation is very slow, glitchy and give wrong directions. I tried both with compass and no compass (excluding it), but I still have the same problem. Please can you help me?
Hi Maikk, I'm not sure. It would be best to submit a bug report with the iNav creators, Matt
Thanks a lot
im trying to run an EZUHF 8 channel diversity receiver to this board via PPM. As far as I can tell, PPM is enabled on the receiver and transmitter but the board refuses to see my receiver input. Please help.
Howdy Daniel, I'm really not sure as I have never used EZUHF before. However try the slack forums here as they will be able to help you inavflight.slack.com
From RSSI on the FC to where? How do i wire this?
hi, i have a problem, just one servo its moving :c pls help (the servo its ok)
Hi Matt how about calibration of the current sensor.
Howdy Martin, I'll cover that near the end. Struggling at the moment as my soldering iron has packed up & I need it for the next part of the series, grrrrrr! Matt
Ha, my soldering iron died last Friday, bought me the Dremel VersaTip
is there a Vtail setup in Inav? thanks
Howdy, yes, see their wiki. Matt
Hello!
F4 has no OSD. What port is that?
GPS, what port?
Howdy cheng, the suggest F4 boards do have OSD's on them. As for the GPS, see the videos later in this playlist, Matt
can you use this flight controller on i-bus?
Howdy fella, as noted in the first part of this series, I have no idea for non FrSky products. See the iNav wiki for more info for anything I've not covered github.com/iNavFlight/inav/wiki Matt
when you fly with inav, do you need to wait for gps lock first? if yes what's the avg time?
Howdy Henry, great question! In short yes. Personally I wait for 12 or more satellites to show on the OSD before arming. iNav picks up the home position when you arm the model. With the NEO-M8N GPS unit, it uses the normal sat network, but also picks up the GLONASS ones which is the Russian sats, thus more accurate & reliable positioning. Hope that helps Henry & ta for asking here :) Matt
Oh and average time 2 minutes, maybe less. Depends if it's a new location or not as the GPS units have a little battery on them and they remember their last location. Matt
this board will fail if you plug the power in when the usb is connected unless you bridge the 5v to ram solder points on the underside of the boards , I missed this point and it killed 3 of my boards , thanks for the tip matt
Jack, I just read your other comment on the other video, if you're plugging them in and they're going pop and you've done that 3 times, maybe change the power supply out? These boards have been fine for me, Matt
thanks for the reply, what do you mean power supply out ? I must admit I am a bit of a magnet for faulty stuff, but lots of people have commented that when they connect to inav and then plug in a battery the board will just not connect to inav anymore, this is what happened to me .
I think their might be a batch of iffy omnibus v2 boards as it happen to me with a boards from gear best and bangoods . I have setups with other make clone boards which work fine and I am following your directions so I don't think it's user error .
I am grateful for the work you put into your channel and have learnt a lot from your vids and I hope santa brings you something nice to show us in the new year ;) .
yep , just soldered the 5v to ram on another omnibus board I have and it seem to connect ok with the power connected , it's just a shame that I seemed to of missed when you mentioned this in your videos , this seems to be a key point in not bricking the board and should be highlighted to noobs
Agreed. I seem to have missed it too. Can you describe the locations of the 5v and ram pads to be jumped? This F4 PRO board is not as straight forward as the plain F4 board. Thanks for pointing this out.
Sorry, I meant this F4 V2 board vs other Omnibus boards. Other board = VBAT to RAM, no probs. This board - 5v to ram, .. Which ones? Thanks again.
40 amps is too conservative if I was running a quad the max esc I can run is 10 amps x4? I run 30 amps x4 without problems with bursts to 35 amps during punchouts.
Howdy Dave, yes that's in a quad where there is loads of cooling, not in a model plane, all cosy in a low airflow environment, wrapped up in insulation foam to keep it all warm on a hot sunny day ;) Matt
hi！ GPS TX3 RX3 ？
Anyone had telemetry work on this board?
enable ppm ?
Please, please, I no longer know what to do, I have 3 control cards other f4 v2 pro, I configure the inav, I connect the rx, gps, all right, but when I connect the servo, it gets a huge delay in servo, I give every command and it goes slowly until the end point, when I release the command it takes to return, and back to the few, when I put in passthrue it works normally, or when I move on the plate it works very fast, it is only us command of the radio that has the delay, what can be? follow the video of the problem ua-cam.com/video/q2SgRFqvyGg/v-deo.html
Howdy, a read of the iNav wiki for the flight modes will help as it sounds like you have enabled a stabilised mode, Matt
this has put me off this board. its too small and crampt for my taste
Hello. I’m slightly lost how to power the servos on my omnibus f4 v3. I understand it isn’t a good idea to use the onboard bec for this? Does this therefore mean I need to remove a diode? Then power via an external bec?
What cable do i need for the gps on the v2 ?
Hey Mads, see video 2 in the series fella for the lead, Matt
Ahhh was going crazy .... ! it's video 2B.... :D thanks so much for the videos ! really making it easier and fun :)
