Can the Plane Take-Off?

I dunno...on a simulator, I've been able to take off at about half the speed I'd otherwise need. I finished accelerating in the air. There are these tricks known as high-lift devices. Specifically, flaps on the wing's trailing edge. Once in the air, I'd pull them in.

Edit: Lemon1324, I know how to fly. The flaps would get retracted once I was at a decent speed, and only when I was at a flying speed. I might not even use them until I cleared the accelerated air, an then use them only until I got a better speed.
