Default RE: What is the effect of flap on attitude?

Ditto... Unless you have knowledge as to what mixes are needed, the only solution is to fly the plane. There is no pitch up effect per se, the pitch from adding flaps can be up, down, or nothing. Unwanted pitch can be offset with elevator and sometimes even crow. The key is to flight test. I'd also suggest slowing down flap deployment and any related mixes to occur over several seconds, many radios can easily be probrammed to do that. The slow deployment softens transition from clean to flapped flight. I generally go for about 5 seconds or so.
