is joystick necessary?
 

Can you help me? Can i use keboard and mouse to controll CoD?

Yes it is theoretically possible to play COD with the keyboard BUT you will find it much more intuitive if you purchace your self a Joystick.

You don't have to have an expensive one (I bought my nephews a cheap logitek Joysitck on special for about $20.00) but it would make it a lot easier to fly and make the sim a more life like experience.

I not sure if I know anyone that actually plays solely with the keyboard.

Cheers!

Get a joystick if you can, preferably one with a twist stick for rudder control. You should be able to pick up a fairly decent joystick for £20-30 and it will make flying a lot easier and more enjoyable. If you have the cash (£30-40), I'd personally recommend looking at the Saitek Cyborg FLY5 Joystick - served me well and has twisty stick, lots of buttons and two leavers which are useful for controlling throttle and propeller pitch.

Yep, go for a Joystick! Flying is possible with mouse and keyboard, but not recommendable.

And go for a Joystick, not a gamepad!

My tip: Browse Ebay, maybe you can even get yourself a HOTAS-System, which I can highly recommend...
(e.g. Saitek x-52).

My 0,02$: Thrustmaster T.16000M - the only "entry-level" low cost joystick with HALL sensor (same of Warthog).
