Adjusters...
Actually the picture above is not of one of my planes, but borrowed from the PL-Prod web-site... I think it's of a Tornado.
The Rhapsody has not been designed to use adjustable incidence, it only has one guidance tap on the root rib. This is made of a 10mm carbon tube.
The attached picture is of my Rhapsody, and it shows the single tap in the root cord.
