Martian II FPV Camera Angles

In case you’re wondering, since it’s not stated in the manual:

The notches for setting the FPV Camera angle are 15°, 30° and 45°.

There you go, Internet, now it’s documented forever 🙂

I fly 30° personally, since for freestyle I think 45 is too fast and 15 is so incredibly slow, you’re almost not moving forward at all.

Have a look at my FPV Freestyle Videos on YouTube if you like!

Ubuntu 17.10: sudo / gksu / gksudo not working, cannot open display

In case you try to start any application under Ubuntu and you get something like that:

fpanzer@nb-fpanzer:~$ sudo gsmartcontrol
No protocol specified
Unable to init server: Verbindung ist gescheitert: Verbindungsaufbau abgelehnt

(gsmartcontrol:4153): Gtk-WARNING **: cannot open display: :0

Try to allow “root” to run applications under your (user-)display:

xhost +SI:localuser:root

Update: if you disable Wayland, things magically start working as they should. Disable Wayland, it sucks. Just use xorg.
