This is a 2-piece wing. They are connected by 2mm piano wires and a rubber band under the bottom. The two short spars are for glueing plastic tubes for insertting the piano wires. The airfoil is as thick as 18mm, a thinner clark Y one.

Pod & vertical stab. of the Alula.jpg
The tail is removable, I applied the same idea as what was taken in Dream Flight Alula kit. But I glued a bamboo skewer to the tail as its reinforcement, I glued two more later. The wood stick glued at the nose of pod is for mounting the motor.
