Each stab fin is 2 pieces. There are 2 holes drilled through the stab from the factory, and a piece of piano wire runs through the stab into each fin and glued. Then the fins are glued to the stabs with thin CA.
This morning in the sunlight I noticed my horizontal stab on the right side is warped. If you look closely at the picture from the front you can see the angle of attack towards the outer edge has negative incidence compared to the left stab. Tried to twist it and rshrink the covering but the stab is full sheeted and wouldn't move. Nothing I can do about it now
Hope it won't affect the flying qualities too much.
