Have to solder a new antenna on my tarnish as well. Ordered a 5dbi antenna with screw on attachment, and I have an antenna identical to the original I ripped out of my STM transmitter. Not sure winch one I'll use. Depends on when the antenna from Germany arrives guess. Ordered tip cleaners and a flux pen as well some can do it properly, especially since my cheap EP2 soldering station oxidized they tips very fast.
As for how it happened, I put the receiver for my new taranis in the Beaver linked it, then off to the computer spent a copleof hours learning to program it, added messages for flaps position, throttle hold switch with on off messages and warning beeps if the throttle was on with the hold on. Some well done programming I was proud of. Now to where I messed up and broke every rc safety rule.
I had the plane upside down on top of the Taranis case in my cramped work room after putting in the receiver, so I left it there for testing all the channels and stuff. It was also laying nose towards me. Did some test and thought some of the channels if no all where inverted, plane being upside down made it hard to tell. This should have been another warning... next brilliant move, release the throttle hold.... oh yeah... it was definitely inverted. Antenna on the Taranis got kicked off and my thumb got a semi bad cut. But it could have gone much worse...
I doubt I'll forget to always test new radio setups involving big propellers outside while holding down the plane again...
