I have had a couple requests/inquiries about some issues I have experienced with my Swift 2 and how I fixed them.

Let me start by saying this was my very first FPV cam, and, in no way, am I disappointed or displeased in it's overall performance. In fact, since I made the repairs/fixes I have received several compliments on how nice the DVR looks!

Initially I did not have any issues except for some vibrations causing a "bouncy" image and focus. As I began to push the quad harder (crashes and hard accelerations ) the vibrations became worse. Then after a week or so of abuse I go out to burn off some batteries only to find on my second battery my Video was saturated red and very dark in the shadows. I flew to see what would happen. Didn't change throughout that flight. Next battery the problem was gone. From there it would only show up from time to time without consistency, then if I unplugged gave it a second then plugged in again, it went away.
This is how those flights looked. Fun flight but hell to see! (turn volume down, I didn't edit it, as it seemed to throw off the sound timing as well, but it is loud. Just a heads up)


Well after a hard crash and rebuild, I decided to look further into the Swift 2 and this is what I found. (besides the loose feeling connectors and PCB)


The PCB had actually looked to be shorting against the interior sides of the housing, where the carriage nut is for mounting the case.


Even had a build up of dust and debris on the sensor itself (that dirt on my finger came off the sensor!)



The Fix: Level Easy!
2 small pieces of insulator, electrical tape or split heat shrink, covering the sides of the PCB where they come in contact with those carriage nuts. (sorry, I have misplaced this photo   ) But you get the idea. Not only has it solved my video image issue but also eliminated the extra vibrations. I have ran probably at least 20 or so packs now since the fix, with zero problems. Love this cam now!

Next step is to get a good focus and fly the daylights out of it.  I found how to use this focus pattern over on RCG's. Time well spent in my opinion

Here are the results after the fix. (Did you see the bird @3:30) (I just noticed it )  


Hope this offers some help!

Good tutorial - nice find on the focus pattern reference!  Just for convenience, here's a link to the actual focus pattern (from rondexter.com):

My Swift2 is having the same video issues as well as having some OSD issues. This too was after a crash. I will have to take it apart and check for the loose PCB.

Thanks!

Very well done job. I have the same problem with my THS, I've mounted runcam nano 3 and the view looks very red and bad quality. Camera doesn't move in mounting, plugged properly. Stock camera work correctly. Does anyone can help me please?

If you take the camera out (unmounted) do you get the same image quality? If so, is there another VTX you have to test the camera. If not other vtx, then depending on the goggles, I can show you how to use the goggles to test the camera.

Yes, I tried mounted and unmounted the same result. I haven't got second vtx to try it. My goggles are Eachine ev100, if you guide how to check what wrong with my set I would appreciate. Btw is there any setting in BF to improve camera quality?

If unmounted from the case and you are still seeing a redish picture then there is likely something else going on.
On my old Runcam when isolated from the case the problem went away.

And as far as I know BF doesn’t have any kind of camera settings, just OSD.

I send the camera back to seller and wait for another one, I hope that was camera issue. Thank you for your help.

Your welcome. Hope you get everything all sorted out.

So I get the new camera, the issue with red view is still there, not that much like before but I can still se red better than the other colours. I tried look at the pictures at the post above with this problem solve but I can't see what is done to it. Any ideas?

In my post above the cameras PCB was just barely touching the back of the recessed nuts in the case. I insulated it with some electrical tape is all.

Sounds like you may just need to adjust some camera settings like color balance/hue.

Can or have you shared any DVR for us to help diagnose?

The camera is Runcam nano 3, this model have no settings to change. My goggles are ev100 without DVR, I ordered separate module, should arrive in this week. The red view is in the middle and on sides of view and sometimes the view get really dark for 2-5s.

Have you double checked the following:
Your vtx and goggle channels match. Also try a different channel to see if there’s any change.
Check that all antennas and connections are the correct type. RHCP vs LHCP vs linear.
Double check all video connections for clean solder joints ect

Just some ideas
