I designed a part that holds the SMA end and a capacitor for the Xhover Win5 (should fit the Win3 and Win4). I would recommend printing it in TPU, that way it makes it easier to get the capacitor and SMA end on and off the part. The SMA end is mounted at a 20 degree angle upward from vertical. I did this because I had issues with my TBS Triumph getting prop strikes because it wouldn't stay bent upward enough to clear 5045s.
Tag @whocaresfpv on Instagram if you make one and mount it! We'd like to see how it turned out for you!
