Damn, dude! Keyboard? I really want you to make full hydra tutorials.
Keyboard, yes.
I use Q and E to control the rudders, A to pile the nose downwards and D to tilt it up. The four arrows to control the plane, and Num 8-2 to control the thrust, Num 4-6 to move the camera left/right.
This is the setup I have used, since 2007, although, I haven't played this game as much as you may think during these years, but it's been a game I always return to. Now I have to really get into real life though.
That I have a really good PC, a keyboard I just love, and the Dell S2716dg has given the Hydra journeys a big advantage...
I don't know how I should make a tutorial? Just observe and learn
just try and try and try, that's what I did anyways.
