Flickering OSD Fixed | Mamba F722 OSD Issue | How To Fix Bad OSD

[@markonikolic5010]

I tried everything I knew to fix flickering OSD on mamba f405 mk2 stack....this was the way to go. Big thank you :)

[@PropsOff]

I really appreciate your feedback. It means a lot to me if the result is duplicated beyond my workshop. Glad it helped you out...👍🏻🍻👊🏻

Hello Everyone! Thank you for checking out my channel and subscribing... Here I share how I fixed "Flickering OSD" when using the Mamba F722.. Hope it helps someone. Enjoy the Breeze...👍🏻🍻👊🏻

[@kylecooper3350]

Tried this on a f405 mk2 and it worked great! Pad configuration is a little different, but the idea is the same. Thanks Propsoff.

[@PropsOff]

You feedback is much appreciated. To know the work-around works for you makes me happy.. Check out my giveaway! Enjoy the Breeze...👍🏻🍻👊🏻

Perfect, that worked a charm. On my Mamba F4 board was getting zero OSD and maybe 30% chance it'd show up and even less that it'd not disappear quickly. Been rock solid just that one wire from the ESC ground to the controller board. I did suspect such a tiny ground wire with all the components would become a problem, didn't expect nearly as bad as it was though. 👍

[@TekkGnostic]

I was misinformed it was a software bug and wasted a day trying different firmware with varying and random results. This fixed everything consistently. Also much smoother gyroscope in angle mode without the resonation.

[@PropsOff]

@@TekkGnostic I have recently built a frestyle 5incher with a Matek 405 FC and individual ESCs I have no video issues. Further testing is needed. I haven't flown much and taking a break from KZbin. Pretty interesting stuff...🍻

[@adamshook5896]

Thank you for this video.. I started having this issue yesterday.. I'm going to give this a shot.. reminds me of installing a ground kit for your car

[@PropsOff]

Let me know your results, please.. It's exactly the way we did it for drag racing. Had an alcohol outlaw that had electronic fuel issues and ran a heavy ground system and that thing broke records. Do let me know. Thanks for checking it out and commenting...👍🏻🍻👊🏻

[@ivi2861]

I tried it with my unify pro v3 5v(bec for cam and vtx) . without wiering vtx gnd to fc gnd doesnt help. But with wiering gnd fc-vtx it works fine ! Thank U Sir !

[@can5projects563]

really nice information hope to see your next video ....

[@TheBoatPirate]

youre definitely gettin into the small stuff there. awesome. its stuff like this that helps people learn. side note: your voice was ringin a bell and i swear, you could be a voice double for fine tune cb shop. check it out. pretty cool. btw, im havin a WEIRD issue with my taranis. im wonderin if you have any idea what it might be. ONLY my roll endpoints are all over the place. adjust in the radio, adjust in betaflight, both endpoints are up to 100 points off after disconnecting. All other endpoints are rock solid. any ideas? im stumped unless i got a bad gimbal on my pretty much unused qx7.

[@PropsOff]

Thank you for the above section..👍🏻 Now, your end points are off on roll, by how much? If you calibrate your sticks then adjust your stick travel using Betaflight receiver tab and "Inputs" menu on the transmitter, you should be able to dial it in resulting 1000 lowest and 2000 highest. Does that sound right?

[@TheBoatPirate]

@@PropsOff it drifts off say 10 to 100 points. i calibrated the sticks and it did make a difference. at least it seems to arm consistently now. i got it a lot closer. gotta knock the rust off these old fingers now. youre the only one i could find to help me find an answer to this. THANK YOU. i really appreciate having anyone at all to talk to about this.

[@TheBoatPirate]

@@PropsOff any idea why betaflight doesnt show the quad in the preview in receiver tab?

[@PropsOff]

@@TheBoatPirate That, I will need to look up again, been a minute since I seen that..

[@PropsOff]

@@TheBoatPirate I have looked for a reason your not seeing your quad in the "Preview" of the Betaflight receiver tab.. Nothing so far. Are the channels showing up and moving correctly?

[@vjvenida3991]

Thank you so much for this video.. i fixed my video blackouts using the redundant ground.. im still trying to figure out how to fix the flickering of the osd, i've wired almost all ground pads to the redundant ground wire. 🤔

[@PropsOff]

I actually had a camera that I crashed give me OSD flicker before. Finicky ground connection or an overloaded 5v rail too can cause it. I had to replace my camera though..

[@vjvenida3991]

@@PropsOff update: I'm sorry I missed the part that you made a redundant ground for the FC too.. My OSD flicker is gone now... Thank you so much! you save me from buying a new stack. :D

[@vjvenida3991]

@@PropsOff I have learned this in college that you have to get a good ground for any electronics. I can't believe I have forgotten that important part.. Thanks for reminding me haha

[@PropsOff]

@@vjvenida3991 Yeah, My college electronic days are from a long time ago, however, the great ground principles apply even today.. Lol I still have not opened the crashed camera to see if wires came loose, I should. Have a great day...🍻

[@BobCorey]

Nice video, I somehow started having about the same issue. This happens at random times, some days doesn’t even happen, or it won’t relate to the throttle. I also got a second 405 MK2 and still got the same thing one random day. I thought it as the VTX so I replaced my unify pro with a AKK X2 but has very noisy video…why is that? (Actually tried two AKK X2) Do I have to do all that weird mess of cables..? XD

[@PropsOff]

Yes, the video after this one is the final result for the best video ever. I spent lots of time placing and removing redundant grounds to measure the difference. Isolating the video system was the best part.

[@BobCorey]

@@PropsOff I saw your other video too. Isolating the video system means pulling power straight from the battery and feeding the camera through the VTX? Do I have to have this regulator in order to do this? Do you know if the 9v and VCC are filtered? I am trying to figure this out because I have spent so many hours trying to fix this thing…

[@PropsOff]

@@BobCorey The BEC (in my video) has an internal LC filter. If you run the BEC off VCC and the camera off the VTX, it is the best filtration. Yes, you will need to have the Matek BEC in order to isolate the curciut (as shown in the "Best Video Ever" video)...

[@javieruriel]

Do you have a draw or some image to do the wiring?

[@PropsOff]

Yes I do... kzbin.info/www/bejne/hYmynoyomt9mqKc

[@JColoon]

Question: it looks like all components need to be grounded to battery in essence = black cables to bat - , right?

[@PropsOff]

Basically and with a redundant.. I took things a bit farther or some may sat it became an obsession to have crystal clear FPV video.. Here's the final version - kzbin.info/www/bejne/hYmynoyomt9mqKc

[@sL1pKn07SpinFlo]

sorry, i'm not ENG native speaker, so,: you wired from XT60 pad to the GND pin output (near the ESC conector) to the GND VTX pin in the FC , from the VTX GND pin in the FC to the cam GND pin, and from the cam GND pin to the VTX unit GND pin. correct? is a FC problem or Tmotor ESC unit? (or both). greetings

[@PropsOff]

Correct, full redundancy of the grounds back to the Lipo ground... I actually when further in the next video and used an LCfilter/BEC. You may be interested in seeing it. The issue is the electronic noise entering into the video output. Cleaning and isolating the circuit is the best way that I found.. I attach that video below.

[@sL1pKn07SpinFlo]

​@@PropsOff you know if the issue is applicable to other F722 mamba series or is only for "F722S" like you model?

[@PropsOff]

@@sL1pKn07SpinFlo I've had to wire many brands the way I did in the last video I attached. Oddly enough, I've not had to do this to two Matek F7 flight controllers (no matter the VTX).. I even run a redundant on AIOs. The VTX, especially HDzero, needs more ground.... A while back, all the components were separated. Never had any issues until the PDB became part of the overall component. I think the PCB and traces have become ever thinner and smaller, creating noise ever more present in the sign wave.

[@califpv]

I'm getting this issue after replacing my runcam phoenix 2 with the exact same one... Not even the wiring was changed. Just plug & play. Can't figure out why

[@PropsOff]

I have a couple Phoenix 2 micros and a nano.. There's one that took a bit of a hit and it will flicker (no reason like you say)... I would ask for an exchange (may have been thrown around in shipping?).. It's strange how one is absolutely perfect and the other isn't for me as well, hum..?

[@califpv]

@@PropsOff got it. Thx

[@PropsOff]

@@califpv I'm interested, what's your thoughts or plan?

[@califpv]

@@PropsOff I just received that cam from am hobby's , so just gonna ask for a replacement. I'll let you know if the cam was faulty. This has never happened, so wish me luck. 🤞

[@staydown.normal5323]

also what caused my problem was the camera worked on pal but flickered a little almost not noticeable but in ntsc it works fine i was trying to chase a bad wire for no reason lol i did add a cap and a main battery ground but it never went away lol it was because i was on pal...... it worked but osd was not perfect

[@PropsOff]

Yes, The PAL NTSC has to be correct. Betaflight default is auto, which is terrible. Good you got it sorted...🍻

[@staydown.normal5323]

@@PropsOff i had it on pal and i thought my camera was both pal and ntsc but i guess not i thought the screen would be black if the came was not pal but it worked just bad osd flicker,,,,,, so i put it back to ntsc and no flicker.... just smaller image now but its fine again.... lol i replace my ground and added one main ground too lol ahaha... it was the camera being on pal ez fix ntsc for the win

Hello, very helpfull video thank you. I have another issue, my betaflight stopped to show videotranmitter menu and my quad vtx do not allow to change 25mw and stuck. Vtx signal very poor and video is cut completely when i start to fly? Can anyone know why?

[@PropsOff]

Your camera is bad or wired incorrectly. Most of these issues are caused by power going in the "CAM" signal too. Check your wires! Did your camera take a hit?

[@BarisBaydur]

@@PropsOff no not a recordable demage or hit on camera. İ guess FC can't get feedback from vtx, maybe fc osd broken or vtx has a problem. İ will check wires or change vtx and will give the result here.

[@PropsOff]

@@BarisBaydur When it fails,, What screen do you have in your goggles? Snow or blk/brown/grey?

[@BarisBaydur]

@@PropsOff black and grey. In the normal arm position the image looks very distorted and googles could not find easily. When i try to fly the drone image is completely distorted and the screen turns black. Also i change my vtx to 800mw but it same.

[@PropsOff]

@@BarisBaydur Did you swap out the camera yet? Just saying. Usualy if the VTX is losing power or failing, you'll get only snow in your goggles.
