Forgive me if I mess up here but I don't do face book and don't have an Ipad. I barely know how to text and e-mail. Computer savy I'm not. Most of what I know is from searching the net anything aviation and info on building my 701. Joe T's control mods were in,I believe, Zenair newsletter #185. Mike N's mods are in Zenair NewsletterCD #189 which is March/April 2012 edition, Chapter 7. I followed Mike's example mostly. Very happy to not have that tension on the cables with Right stick deflection.
