looks like there is no dihedral in that first picture.cosmic said:The aircraft in the video link mentioned in ifida's post (number 5) is a Sonerai 1. It started out as a stock standard Sonerai 1 but in 2000 the decision was made to convert to a low wing and to power it with a Jabiru 3300. A number of modifications have been made but apart from the change to low wing, the aerodynamics are unmodified Sonerai 1. The performance and handling is first class and a tribute to the design skills of John Monnett. Attached are pictures in 2000 and in 2018.
