Yes, the key mapping takes time. It's like:

You think: "Hmm... I need flaps."
then go to controls and assign a button.
Game says: "flaps:combat flaps:takeoff flaps:landing"
You think: "Hmm... This is an unhandy place for the button."
Go to controls again and assign a new button.
You say: "Woohoo! This is Da place for the flaps down!"
