Hi Chuter,
I never got in the air long enough to even evaluate it, and to be completely honest, even if I had got in the air,I was very unqualified to judge it's effectiveness back then.
In retrospect, I really had no business putting a V-tail on my Bee in the first place! Beginner gyro pilots have no business making major aerodynamic modifications to a proven design until they have some proper flight experience to even know what's normal or abnormal fight behaviour.
Now that I have accumulated lots of hours on my Bee and a little time in several other style gyros, I'm perfectly content with a simple conventional style tail. At this point I don't see another V-tail in my future.
Best regards,
John L.
