Paul Lipp's email got me to thinking about it. Here's what I did: 1. I adjusted the flaps so that they would reflex well above the strakes. 2. I decided not to get a digital level. 3. I flew a constant power, steady altitude, at what I consider to be an average gross weight and a typical high altitude indicated airspeed. 4. I bumped the flaps up and down, letting the airplane stabilize before making the next change. I noted the change in indicated airspeed at each flap position. 5. The result: Flaps aligned with the fuselage strakes (Lancair 320 Mk II) gave me the best performance. Any comments? What did I miss by not using the level? Bill Kennedy N42BK
