X4 busted connection repair

1

Was ready to launch with my X4 yesterday morning - turned the main switch ON - heard the ESC(s) synchronizing, but no red light atop the throttle and a blank screen welcomed me🤬
99% of the time it is a busted solder, and it was! Repaired it last night. I can’t remember how many time that happened. The handle housing is tight for the number of wires to fit comfortably inside it - it always requires some jiggling/pushing/pulling the tiny wires around to close the half shells. Sometimes the cable to the ESC is yanked back during an inflation for various reasons and a solder or wire will brake. Doesn’t take much to screw up a connection, even with the SP.
Hard to see but the black ground wire is disconnected (zoom in on the vice and where the black wire is missing)).

Sorry Bill, am not. I like it in spite of its ailing moments. I always managed to fix it so far. It looks a bit banged up but that’s ok,… that way I do not feel bad adding more parts to it or drilling holes or cutting out carbon fiber parts🤣.

Looking back at that first version of the controller gives me chills!
We thankfully upgraded to a custom PCB after that so there weren’t so many wires in a tight space.
Glad to see it lives on. That’s a piece of history :slight_smile:

As long as I hear the beeps, see the screen ON and the red light, that’s all I care about😆
