The original Jonkers family just grew bigger last year! So, as the new JS3 Rapture was competing in Benala, Australia, Matjaz instantly fell in love and decided to build a new, big model. After being lucky to receive a useful three views image from the company, I started designing our model in February. After very short six months, our prototype in scale 1:2 had it's first flight. We are very proud of our new product for which we had several requirements:
- 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:
- very good electric power train from Andreas Reisenauer
- proven airfoils from Dr. Helmut Quabeck
- fuselage made from two easily joinable parts
- two part wings with separate winglets
With original's wingspan of 15 m and our 1 : 2 scale the model has the following specs:

7.500 mm |

length (overall) |
3.470 mm |
