hey dave!
N522A came to me with a whelen strobe on top of the fin. it looks as if it was done when the a/c was last recovered as the base is much wider than the stock base and the fabric is very nicely faired into the larger strobe base (sounds more complicated than it is).
after my first night flight, i ordered a red/white lens as the white flash produced an intolerable reflection on the back side of the prop (even tho it's painted flat black). now, the red flash is perceptible, but not annoying. i only wish the lens was a little more "tear-drop" shaped, not just round (round is VERY draggy). if you need pix or further info, just let me know.
blue skies,
vic & N522A
