All,
Below are a few videos of the test I did this weekend. I have not fully analyzed the videos yet but there is plenty to fix based on what I am observing. The one that caught me by surprised was the reversed airflow in front on the cowl flap when opening over 1.5 inches. I expected the turbulent flow below and aft of the exhaust pipes. I will be making a fairing in the future and repeating the test. I will also be modifying the cowl flap.
Hope we can all learn something, this is just cool stuff.
