You wrote: "I need to tuft the wing root fairings and the bottom of the elevator when I have a chase plane and see if there is separation at high AOA." I think that you will be essentially wasting your time using visual observation from a chase plane to interpret air flow by yarn tufts. You will get a simple one word answer to the question "........see if there is separation at high AOA". That answer can already be predicted as "Yes". But just how much separation and where will require a more extensive data gathering method. I say this after watching on a DVD an extensive amount of KIS TR-1 air flow tuft testing done by Julian Bone. The results were very interesting and useful because he gathered the data by means of video cameras mounted on his plane. This meant that the data could be gathered relative to different airspeeds and analyzed over and over . See attached still picture. It would be extremely unlikely that you could get any comparably useful results from the visual observation of a crew member in a plane flying formation with your plane. As an expediency you might want to try to equip that crewmember with a zoom capable hand held video camera to see if that would provide some useful data. Take care when flying two planes in formation at high AOA.
