Just a warning to all. Flaps change the drag, and lift of the aiplane's wing. It also changes the theoretical center of lift of the wing. Bascially, a balanced plane has the CG at or near the CofLift. Flaps change the CofLift, thus, IF the CofLift stays in front of the CG, then the plane will want to nose up ("baloon"), then the correct elevator input is to push forward to keep level. If the CofLift moves behind the CG then the nose will want to go over, and the correct elevator response is to pull back to keep level. There is no "right" answer to what to do without experiencing the behaviour of your own particular plane.

Further, there is not necessarily a linear relationship between the degree of flaps, and the elevator response required.

Basically, when using flaps, be even more on the ball.
