About this 3D model

This plane was supposed to fly at Inter-Ex 2016 in Versoix/Geneva. http://jivaro-models.org/interex_2016/index.htmlThis is a meeting where you see objects flying which seem to be unflyable :-) This model is more for fun than to be a sophisticated aerodynamic airplane.You must have a lot of expierence to be able to ride this crazy horse.We had to try out several CG points and trimm settings for the elevons.Finally it flew but something happened that caused the crash. Luckily there was a rapeseed field...https://www.youtube.com/watch?v=L9iDHNIykRQExcept of the front fuselage all has remained unhurt. As next I will try a different shape of the elevons and set them more backwards.Then we will try it again :-)
