New Omnibus F4 Pro V2 installed.
OSD now working  ::)

Just have one slight issue with LED strip.... When powered by lipo and usb the leds work perfect. When just Lipo they are not the right colours and dont change on arming etc....
I did retry the CLI resource MOTOR 6 NONE , then resource led_strip a8 but no difference.
I am guessing it's a 5v issue. The Omnibus F4 Pro V2 has 5v issues as they made it with a 1A diode not a 3A one!!!! But I am only running rx and the LED from the built in 5v. VTX and RunCam slit are from 4in1 esc 5v regulator.

Anyway will have a look at LEDs later. For now it is all together (minus props) including the vtx and antennas. Still trying to work out how to get the VTX03 mounted as it is so small and wont quite fit where cable ties will hold it well not with the button accessible and the display visible.
Anyway I will get some picys soon.

Ched can you please add some pictures or a small video. Just curious to follow your build and maybe get some ideas from it.

Back to square one..... :banghead:
Testing voltages to see why the LEDs are not working the FC just stopped working!! No Leds, tried different USB cable, different computer, flight battery nothing!!!!!
I am sure I didnt short anything or apply power where it shouldn't have been. I have lots of experience working on fault finding at component level so I don't think it was my fault......

Think I will give up with Omnibus FC even though it fitted all my needs.

So once again build on hold.   :cry

Right, after lots of searching for an alternative FC with all the bells and whistles I would like I can't find one!
So after 2 Omnibus F4 V2 Pro clones and unmannedtech (UK Airbot supplier) having a V2 image on their V3 product and them not replying to emails I have decided to go with GdLookinMingeR's suggestion of a Matek F405-OSD F4 ( see: http://www.multi-rotor.co.uk/index.php?topic=21825.0.
So I will order on from a UK supplier in the next few days.

Hopefully my build will get finished soon  ::) Not that I have time to fly for another 2 weeks....  :cry

Cheers, good to know you had a working one  :smiley:
I would have bought the pdb but it wont fit in the stack! I only have 2mm to spare! Actually thinking about it that is not true. If I moved my rx from the top of the stack I have extra space....... Now there's a thought. Can I find space for my rx??? That way I can get a current sensor  ::)
I will have to have a look and see if there is any space for rx. The rx is a Flysky x6b so 35mm x 20.
then again that means the RunCam Split is on top so the sd card cant be removed..
Lots to think about.

Change of plan. Decided I really wanted current sensor  ::). So ordered an Omnibus F3 Pro V2 from Unmanned Tech. So hopefully an original Omnibus will be reliable. Just have to avoid the inbuilt 5v supply. That's no big deal as my 4in1 esc has 5v 3A regulator which will be fine. 0.6A for RunCam Split, 0.4A LEDs, 0.6A vtx03, plus x6b rx and the F3 it's self. So I should be OK with 3Amps.
Should arrive Wednesday, Thursday  ::)
