Also, note that the strings are frayed as well. That will amplify some of the disturbance. Another factor is the diameter of the yarn. You wind up measuring airflow too far away from the fuselage. That said, very impressed with the work. For the next round, I would suggest using flourescent fishing filament taped to the fuselage every 3-4 inches. That will give you a better indication of airflow. Though I have to say, I didn't see anything wrong with the airflow.... taking into account the fray and large length and diameter of the yearn. Very nice. Thanks for posting. I love the videos.. Nice flying too!!
