Yes, Mehari has some similarities to DR-107, Lazer, and Extra 230. But at the same time, there are many differences. The airplane size is smaller then an Extra230, but it is bigger then DR-107. We try to use high aspect ratios on wing, tail and also fuselage (length / mean diameter) in order to give to the airplane a good visibility at the sky. We also believe that a more "stretched" airplane is better for flight qualities. During the design we spent many time trying to adjust the flight qualities (deflections and force per g in any position and airspeed, as well as post-stall behavior) in order to have an airplane that is easy to fly, despite its small size.
The ailerons design is quite innovative. We try to make it more effective on the wing tip, as well as Mr.Extra try to put on his new 330SC, but with a different approach.
This prototype was build with wood spars on the wing and tail in order to save money. Now, after flight test programs, when we are sure about the airfoils and geometry, we will use these wings as a model to build new ones, with molds, and in carbon fiber (vaccum pre-preg). With this we intended to save, at least, 30 kg.
