This looks awesome. I'd like to have that size screen on my reserve flight deck and have the screen blink furiously if a Cessna is coming up from behind the paramotor. Perhaps a BT alert into my headset instead.

For a permanent power supply the mausberry PS seems great. 4amps and auto on/off when the car shuts down
