Two MMCX to sma adapters mounted to the transmitter with two Bluebeam Ultra's opposite of each other with a Mad Mushroom and a couple of 3 turn helix's on the ground should be a huge improvement.
This is all you'll need for heavy soldering jobs. Handles thick copper PDB's with ease.

That is absolutely the wrong way to ever setup a FC that has GPS and RTH. SuperX is very simple, +100 ch 6 only.
Not setting up fail-safe is putting you and others at risk on the ground.
If there was an issue with a motor or esc. Switching to manual or fail-safe wouldn't have made a difference.
Was the FC still secured after the crash? Looks like something might have shifted mid flight.
Hard to tell without actually being there when it happened.
SuperX with Taranis using S-bus, after 15 months I am just one flight away from reaching the 100 hour mark.
Video I posted when I first received my SuperX.
