the ribbon from relish or stock?
for me stock cable always worked better and lasted longer than any ribbon cable I tried.
I don't remember exactly because it's been long time ago but I damaged my original stock cable after maybe a month in a crash.
after that I went through 4 ribbon cables from Relish while waiting for stock cable replacement from 3DR.
1st ribbon cable lasted 1 week, the other 3 lasted 1 day each.
when the stock replacement cable arrived it lasted 2 months.
after that I was unable to fly because 3DR were out of stock on HDMI cables for couple of months, this is when I ordered 2 ribbon cables from Aerialpixels, one was same design as Relish and the other was reversed-right angle at one end (the one at the top in this picture) :
I installed the reversed right angle cable and it lasted 1 month (by far the best ribbon cable I ever had), I had few crashes in that month so might have damaged the cable because of that, I don't know.
then finally I got new replacement stock cable from 3DR and I'm still using that one now (2 months now I think).
the reason why I don't like the "standard" ribbon cable I explained here (3rd paragraph) :
Frustrated, needing some help.
What options did you chose?
3.9 inch two type D flat?
these were options on my order for the reversed right angle cable :
the reason I ordered the reversed right angle version is that this cable does not require the 180deg twist along the path.
the other ribbon cable from Aerialpixels which is identical in design as Relish :
I ordered this one because I assumed that both ends (connectors) are not opposite to each other, but in fact they are, just like the Relish cable so I never ended up using this one.
