Mini fin for tbs crossfire race antenna

thingiverse

This is a MINIMAL shark fin - AKA anti-turtle fin. It's made specifically for the crossfire race PCB antenna. If you don't insert the race antenna into this fin, the fin is pretty much useless as it is TOO flexible. Print in TPU 20-30 % infill. There are slots to use zip ties. This design sacrifices durability for light weight. It's about 4g or less. It's VERY snug, but as you can see the entire PCB antenna fits into the slot, including the heat shrink. You most likely have to use tools to get the antenna in and/or warm up the print. I used some small needle nose pliers, tweezers, and a hex driver to gently push the antenna in. There's a step inside to make room for the solder ball and the heat shrink. When inserting the antenna watch that you don't get hung up on this step. See cutaway drawing with step highlighted in red. The solder ball on the antenna should face forward. Use at your OWN RISK! It's tight so the antenna doesn't slip in a crash.
