Its not really hard...

good choice, mouse can be better at some things, I like it for camera in most games.

nice skills, is hard use keyboard

CherryPie flying, Cassie singing. I don't know why, but this is awesome.

I play with Mouse and Keyboard.

That's a helpful skill if u wanna get through fort zancudo and avoid getting wanted level with heli, so u just drive heli through the tunnel under it. Much faster way than flying around it ;P

You have controller o Mouse and keyboard? With controller is easy fliyng helicopters, good video.
