I used the flaps(first time I've ever used them) on the maiden (of the GP Cherokee) because I have a short runway. I did a take off attempt without the flaps and found that the flaps were necessary for take off and landing For landing fly a few approaches without the flaps and see if they are needed.( For a 2 position switch) drop the the flaps on about half way down the downwind leg and use for landing.( For a 3 position switch) About half way down the downwind leg drop the first set of flaps and then when on just on final, drop the last of the flaps. Have an experience pilot beside ya and just relax. For landing fly a few approaches without the flaps and see if they are needed. I love using them, they make the landing look very cool. One more thing, take a video and pictures and post them.
