ASW Helicopter

A helicopter equipped with a dipping sonar and 2 depth charges, also has 2 harnesses which can be used to rescue people. The depth charges are more for show than to actually destroy submarines, considering that
a) If you're flying solo you have to jump onto the other seat
b) They require a direct hit, and since there is only 2 of them the chances of that are relatively low.
If you still decide to use them, the optimal dropping height is ~20 meters when stationary, haven't tested dropping them in-flight. Once released, after 3 seconds their (very sensitive) warheads are armed and if they bump into anything they will detonate. Dropping them from too high will cause them to detonate upon hitting the water surface, and dropping them too low can (theoretically) cause them to actually not gain enough velocity (1 m/s) and not detonate upon hitting a submarine in shallow waters. The same might happen if the submarine is too deep, but again, I haven't tested them that much.

Controls are straight-forward. Turn on the key right next to your face, wait for the engine to spool up to 10 RPS (Might take a while) and then you're good to go. W/S is pitch, A/D is roll (You can turn using roll when moving), Up/Down is collective, and Left/Right is yaw. The helicopter is pretty slow, but you can make it go faster by editing the microcontroller in the back (Look for something about max pitch and increase it), though in my opinion it looks stupid when pitching that much. The only seat keybind for the sonar operator is Space, which opens the hatch for the sonar. Then you can control it with the buttons in front of you, which are self-explanatory. The left screen shows depth in relation to the sonar, and I bet you can figure out the right one. The cables are 40 meters long, but I usually hover 20 meters above the surface so it doesn't take as long to lower/raise the sonar.

Now time for credit.
