pictures of VGs

I fixed the VGs with clear silicone therefore I used the templates to draw the line with permanent black marker and then stick the VGs over. Quite a job. The amount of silicone on the VG must be right otherwise messy or not enough. I'll take pictures and post them over the weekend. No change in fuel...

For all Cheetah lovers , here there are the results of the flight test before and after installing VGs on my Bushcat.
Very impresive ! Now I can call her a real bush plane.
