ACE Submarine by KemGus

I've seen a request by few people so here I am - publishing my concept submarine. The whole purpose of this is to teach you how to make one

All you need is Fin3, wiremod and ACE for that.(primitives too)

Controls:
WASD - movement
Space/Alt - up and down
M1 - to shoot left torpedo
M2 - to shoot right torpedo

The guidance on torpedo is dumb, so make sure to have a direct shot.

Systems included:
RDC's public sonar E2
Fin3 control surface SF
Dynamic buoyancy with PID controller
Ballast system with PID too
Propeller movement system
