The ASK 13 is a replica of the original, completely in wood construction. It is a fully aerobatic model.
The construction of the fuselage wasn’t so easy, since there were some changes to the original plan. It was a luxery to have both sides of the fuselage at the same time on the plan, but unfortunately they didn’t match together!
That, however, I first found out when I took both sides of the fuselage from the plan. It wouldn’t have happened if I had checked the plan before!
The rear part of the fuselage had only little variation. The fuselage nose, however, had a difference of 8 mm! So I had to work hard, bending and forcing a lot of glue, to get it in line.
But at least I learned how to do it like it was in the older days – using oil from the kitchen! Building the wings wasn’t a problem. Plywood wing rips and laminated side pieces stuck together with plywood gives you a great construction. The 2-mm balsawood covering helped the construction.
The building of the tail plane and the rudder assembly also went smoothly. They were both made as a coving joint.
Building specifications were both detailed and exactly right to the point.
