As the company Jonkers announced it's new JS4, Matjaz saw a good opportunity for himself. With a light modification of the fuselage and new wings there would be a new model in his portfolio. As the original has a wingspan of 18 metres, our 1:2 scale model would have stately 9 metres!

Again, there were the usual goals for our design:

• fully autonomous self launching capability
• good flight performance
• transport friendly parts

Since we allready have some experience with building bigger fully molded models, we realized our requirements with known solutions:

• proven airfoils from Dr. Helmut Quabeck
• fuselage made from two easily joinable parts
• two part wings with separate winglets

With original's wingspan of 18 m and our 1 : 2 scale the model has the following specs:
