Hello Dico:
As I recall, I ordered the strakes directly from Mike Custard about 10 years ago. They were the cheapest option I had ever purchased for my plane (less than $ 300) and also the easiest to install.
I had just started the painting process on my plane, when I heard about the strakes, so I stopped painting and waited for the strakes to arrive. As I recall, it took about 2 days to install, start to paint.
I have some photos of the installation process, if you would like to see them. I don't have Mikes
address or contact info, but Im sure the folks at lancair might. As you can tell, I am a real advocate
of his product.
Keep up the photography.
Regards, Bill Hogarty
