If the theory is correct then the diode layout should sense that the servo rial is being used and power the board as well. Need to make sure that the BEC or Sbus has enough amps. I always power the camera and vtx from a separate filtered supply ever since the first days of the diagonal lines with fatshark vtx.  Actually I dont on the CL Racing F4 boards as they have a super clean power supply.  If you want to use the volts monitor then the LDO would need to be chopped though.  Also there is the issue of only 4 channels on the FC so flaps will need to be a permanent bypass from the rx.
Anyhow I am struggling to find any info on the pinouts for iNav for the different boards, so thats quite a stumbling block for anyone starting out. I thought I had seen one but cant find it now.  Found this though

Nice, well put together video. I am coming to Bali in May.  ;D

  Ok, I have it hovering reliably, I had to reduce the P values to stop it going mental at takeoff.

 Although it hovers it still gently wobbles constantly and I can't help thinking these floppy Slo Fli props are part of the problem...?

 Anyhow, I have some similar Gemfan Carbon stiffened ones which do seem better, so I will balance and test them in due course. Bottom line is that it's working of sorts, but Im not happy with the wobbly hover.

  Alternate better quality props..Im using 8 x 4.5s.....1400kv motors.....3S Lipo...?

  If anyone has some PIDs they wouldn't mind sharing??....if only for comparison?

Talking to the Omnibus developer/inventor, Teralift,  on RC Groups and asked him for his personal recommendation for which Omni board he would use for fixed wing iNav. His answer was F4 v2 non pro with the LDO removed and a 5 volt sbec. Also he has said that any Omni board that is not blue is a knockoff.

I then asked him for further clarification. E.g. what and where is the LDO and how does one remove it and does the sbec provide power to the board or the servos?

He sent me this link, which I will need to read at least 4 times to grasp.

https://www.rcgroups.com/forums/showthread.php?2790167-OMNIBUS-F4-LDO-woes

And more importantly for iNav fixed wing use, this

OMNIBUS/AIRBOT F4 family: ESC_5V Isolation
https://r.tapatalk.com/shareLink?share_fid=8309&share_tid=2874687&url=https%3A%2F%2Fwww%2Ercgroups%2Ecom%2Fforums%2Fshowthread%2Ephp%3Ft%3D2874687&share_type=t

The more I get into this the less I want to do it. I do not have the eyesight or dexterity needed to desolder micro diodes and such like. I donít get why this is not mentioned in iNav wiki? Or is it and I have not seen it yet?

 Hi m8,

  You won't need to, if you want to use servos and in particular if they are digitals or high current, then ensure they have a separate 5v (or higher) supply to drive them which is not on the servo output rail....(as you initially suggested)

  It's worth noting that my Falcon works perfectly with servos running using the Motors ESC Bec on the rail, but if they were high output servos or digitals then it's maybe not such a good idea in light of this information.

                                                                                                :vulture:

  Update Time:

  I now have the Quad wired up as I need it for FPV...So, an LP filter providing clean VBATT power to the FC with the FC board running via its onboard 5v Linear Regulator.  The 5v BEC supply from the ESC has been isolated from the Motor output rail. Im hoping to use this spare 5v supply to top up My Mobius Camera if I get it to fly FPV.

 I now have Betaflight installed and am using PWM ESC Protocol, but the motors are not running smoothly at all when I attempt to take off either in Angle Mode or Horizon....Unusable.
  Is this what they call de-syncing..?

                                                     Heeeeelp                            :vulture:

I think you are correct with that theory. I would power the ESC from the board not the board from the ESC

 Hi M8,

  Yes, your info about the onboard 5volt diodes has now made it clear, he with the most voltage wins..!!!

  So, i did some measuring, the onboard 5v Reg measured 4.78vdc
                                         and the ESC BEC....................5.25vdc

 So, if I understand it correctly, if you power the servo rail with the voltages as above, the FC will end up being powered by the supply from the ESCs BEC  (which will be noisy, especially if you have digital servos hanging on it)...
  So your suggestion of using a separate 5volt servo rail is justified....:)

  On the Quad, I have not used the BECs 5 v supply, just the signals only, which is normal practice for a quad I think.

                                                                                                 :vulture:
