Free-Camera-Mod in Hangar:
Nice add-on for HangMan (not mandatory)
Left-Shift + F3: enabe/disable freecam
W, A, S, D: Move Camera
E, Q: Move camera up and down
P: smooth camera movements (inertia)
and much more, see included XML-file.
You may also set a key(-combination) to disable elements of GUI (graphical-user-interface), so you have an unhindered view.
But be careful: You can only leave the non-GUI-mode by closing the WoT-client (by pressing ALT-F4) or setting a value for restarting the client!
Unpack into your current res_mods-folder, e.g. C:\GamesWorld_of_Tanks\res_mods\0.9.13
