Default What is the effect of flap on attitude?

I have been meddling, I mean programming a DX6i transmitter for my few remaining intact planes recently, and I would like to understand the effect of using flaps in level flight.

I realize that they tend to add lift and drag, and hence the plane may fly slower, (and possibly be more likely to stall at low speeds?)

But my real question is - does adding flaps pitch the nose up or down? As they are behind the CG, I would think that they might tend to lift the tail rather than the nose.

Maybe an irrelevant question, but anyone got any thoughts? I appreciate all your comments...Chris
