Scott,
Thanks, the cylinders are plans built from Cubmans website. You can find a link on my build thread on the 1st page. Just do a search in this forumn for my build thread and check it out. I go over the entire build from start to finish and cover just about everything that you may have an issue with during your build. The wing struts are also custom built and I cover this as well.
Later!!
Anthony
ps. I noticed someone posted the link for Cubman's website as I was writing this. Check it out you will find all the info you need.
