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 disc= overed that I don't like retracting the flaps unless the IAS is about 135kn= ots 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.
So I guess I am wondering, if you only have a couple people on board (or ev= en a full load with lots of runway), do you use flaps?
