many thanks to all :D
in my first year of papermodelling i did build models from ojimak,
then i decide to made my own template.
the point of my model design is
1. how to make it fly (yes, it can glide
)
2. how to make the airflow as real as possible with the real one
so i can use my models as an education too for the younglings or teenagers who have an interest on airplanes
