Enjoyed setting this up but it wasn't without challenges. Here's what I learned setting up for a podcast in the car for the first time:
1. IBIS is not enough, should enable active stabilization in the FX3s (got really soft suspensions on my car but still not enough)
2. Have a proper back-up plan for audio (the sennheiser ew-dp system glitched and the backup wasn't optimal)
3. Tighten things properly, the back camera drifted during the ride
4. Consider front cameras placement as they were showing up on the back wide shot
