While flying the Sailfly x yesterday, power completely cut out, loss of control and vision.
Once I found the quad it appeared the battery was simply dead, however it was only 45 sec into flight time with the GAONENG 3s 300mah.
The quad powers up with the USB connected, the motors actually do work once I plug the battery in…
Therefore does this mean the issue is purely with the XT30/voltage regulator which is soldered to the FC, not giving proper V to power up the quad? But still enough to make the motors run once the USB has powered up the quad?
Again, there are no LEDs lighting up or sounds when plugging any battery in, only with USB.
The motors don’t work with only USB (normal), however if I plug in the battery, the motors work as long as the USB is still plugged in.
I do not believe there’s any problem visible, perhaps the regulator is blown? The ‘100’ labled chip on the board in the photos seems to wiggle slightly, otherwise everything seems ok.
Since the motors still work with the battery is the FC still salvageable?
