Dico:
Great films: Nice job.
I wasn't going to mention it, but then thought why not
There appeared to be an appreciable amount of yaw occurring in your first film. I mention
this because I found the same in my IV-P, especially at low speeds.
While this might be a normal routine situation, I found it objectional. My solution was to
add the "strakes" that Mike Custard produced sometime ago. It seemed to solve my problem.
Please believe I am not trying to say you have a problem. Just relating my experience.
