My Immersion Vortex 230 tends to just disconnect from my radio as if I shut off my radio... and it falls from the sky.

The fix shown in this video appears to help, but I can't be certain because I've only flown 20 flights since my small fix.
The VORTEX is the best drone I have ever owned for the simple fact that it super agile at high speed. If you'd like one, here is where you can get it: https://amzn.to/2rE0EXT
