So these Immersion RC antenna connectors break all the time. Here is how I repair mine. I have done several like this and it works great!
Yep, it broke again ..
I use this:
1. A antenna extender available everywhere.
2. Some heatshrink.
I cut the antenna extender and strip the wire.
Clean and solder on at these pins.
Wrap around and use some heatshrink.
Shrink a second piece over the other one.
As good as new...
Easier to mount now too and won't break again !
I show how I design a micro quadcopter on TinkerCad and then print the design on the XYZPrinting da Vinci Jr. 1.0
