Hi All, I am wondering how many people use flaps on take off with the IVP? I was told to use about 15 degrees of flaps. I've also discovered that I don't like retracting the flaps unless the IAS is about 135knots IAS. No real reason other than I notice that you don't really feel the retraction as much as you do at the lower speeds.
