That's why the yaw mechanism is there. The tail motor is tilted to compensate for the lack of a CCW pair (it's usually the one placed differently, although OP's design is still useful). It also allows for graceful turns and banks (unlike a quad/hexa/octa, which uses the rotational speed difference between motors). Tricopters are generally more unstable because of slow/unresponsive tail servos (that's where the fourth motor's computational need goes), hence the bigger average frame size.

Great 'Ible. The tor-browser package is already in Ubuntu's official repositories, so I don't think you should've written that. And PLEASE, PLEASE tell the readers that is only for Ubuntu and its derivatives. Otherwise provide the link/instructions for others to install (I'm not talking about compiling anything here, just dpkg -i and rpm install). No beginner deserves such treatment.

Tor is now an independent nonprofit organization that lives off volunteers. The code is available. Have you checked it? Even the Internet started as a state-only invention, but after it became too big, it couldn't be held centralized. TAILS is made to wipe everything after reboot (the A stands for Amnesia), so it's not that practical. Besides, TAILS does EXACTLY what @boompjes described in the steps above, just that this approach is much more user-friendly.

Do you by any chance know M. Bartl IRL? Yes, the exit nodes are getting squashed, but the mixing going on in the relay mesh provides decent (as much as low-latency can get) safety.
