I threw the Supafly tune on it and it works pretty well. Gonna try the 2.5 pitch props next. I really like the vtx power and being able to put it in pit mode at the push of a button. I have some video lines on screen and wonder if I need to twist some of the vtx cam wires to clean it up. • Posts: 753 Threads: 20 Likes Received: 612 in 423 posts Likes Given: 779 Joined: Jun 2020 Reputation: 31 01-Jan-2024, 04:06 AM (This post was last modified: 01-Jan-2024, 04:10 AM by brettbrandon.) I do not see a capacitor listed in the parts and I can't see one in the pic. If you do not have one, you may be able to clean up the vtx by installing one.

It came with the aio and is tucked above the aio with clear shrink tube, and black shrink tube on the posts. The FC kinda lights it up. The aio also comes with a practice board to solder on. I just remember hearing about twisting certain wires with the negative wire and not the positive on some vtx wire routing. Not sure though.

Twisting the wires does help as far as interference is concerned. I think that when you twist them, the ground wire is sort of acting like a shield sort of like in a shielded audio cable. I twist all the wires including the camera and motor wires. Any wires that have power running through them. • Posts: 753 Threads: 20 Likes Received: 612 in 423 posts Likes Given: 779 Joined: Jun 2020 Reputation: 31 01-Jan-2024, 07:56 PM (This post was last modified: 01-Jan-2024, 07:56 PM by brettbrandon.) Here is a pic from one of my latest builds showing the camera, vtx, and motor wires twisted. I get virtually no vtx interference on this quad (it also has a capacitor)...

I don't really twist mine, but do run a cap on the power lead. If you are in an experimental mood, try dropping a small 100uf cap on the VTX power pads. it doesn't need to be a massive chunky cap since most VTX run from a 5V pad, so a 6.3V or 10V cap should be fine, if it runs from a 10V or larger BEC circuit, then size the cap accordingly. That should smooth the power going to the VTX. If you are still having issues though, i'd probably check the antenna and maybe try a different VTX and see if it was a hardware issue.

It does feel like an improvement. • Posts: 5,904 Threads: 47 Likes Received: 2,786 in 2,248 posts Likes Given: 7,686 Joined: Jul 2019 Reputation: 97 (03-Jan-2024, 02:57 AM)Pathfinder075 Wrote: I don't really twist mine, but do run a cap on the power lead.

Hi Pathfinder, I had never thought about using a cap on the VTX power pads. Hmmm. Sounds like a good idea that I should try. Now, you have got me thinking. Installing a cap directly onto the 5V circuit like that would stabilize the entire rail. Hmmm. Yeah, I will have to give that a try. Good idea! Thanks, Mate. Later, iFly • |
