I have a cheapo FlySky FS i6X RC transmitter / receiver from an earlier drone project, and I wonder if it would work with the Flight Core v2 before I go ahead and purchase one of the more expensive recommended options like Spektrum or FrSky (or the RadioLink AT10 suggested in another post).

I am trying to setup my new Flight Core 2, but when I connect it to a USB port on my Windows 11 laptop with QGC 5.0.6 I get a message pop up saying "Power surge on the USB port".

The Flight Core 2 also got pretty hot -- I hope it didn't get fried!

Also, I am not clear from the rather brief documentation what file I need to download and use for the firmware update.

Do I need to use SDK 1.1 specifically or should I use the latest (1.5)? That directory contains

modalai_fc-v2_1.14.0-8.104.3.px4 05-Jun-2025 22:37 1786598

but the doc mentions voxl_SDK_*1.1.0.tar.g.
