I personally dont need it. I do have a sim and when I cant get to the field to fly I use it instead. BTW the sim is in no way a game. Anybody that says so is blowing smoke.The copilot to me is "cheating" and anybody that has to fly with one is not really flying the heli he is just watching some gadget fly it for him. You cant say that you have mastered the heli if you have to use a copilot in my humble opinion. My grandmother could probably "fly" a heli if equiped with a copilot.
