Bob,

We are trying to keep the F17 Tuning Guide up to date, so we will keep making updates as more information is being shared. Here is the link to where the Tuning Guide is.

Look at the bottom. You can see it there, however, it has not been updated yet. I am hoping to move it or copy it to the Nacra Class website:
