sNi-FPV - Drive of the day - Head Tracker Prototyping

Prototyping for a build of a FPV-Crawler with normal Head Tracking plus a "lean" axis to be able to see what the wheels are doing. :) This is just a first try on a too small RC-Car that is way too fast for this, but I finally managed to attract my daughter to try at least! :)

Other:
Radio: FrSky Taranis QX7S (with Crossfire Mini Module)
Goggles: DJI Goggles V2

The head tracking data get sent to my QX7S via Blue Tooth and then sent using crossfire to the car. It uses the RC-Cars own 2.4ghz control link for steering and throttle and I use the 5.8ghz DJI-system for video. In the final version, the control link will be either ELRS or TBS-Crossfire. I have not decided yet. :)

I first saw the "Lean out" idea in Josh Tulberg video here: https://www.youtube.com/watch?v=PgaO3EkDxPQ
