Here's the link to my posts of when we documented the installation of the original "upgrade package" in our factory demo CH601XL aircraft, starting back in November 2009. There are many photos and videos: Installing the "Upgrade Package" to our Zodiac CH 601 XL (this is the first of 26 posts, with many photos and videos).
Other builders have also posted info with photos and videos as well.
