The new wider spar root angle does not fit the root top skin. The old one also does not fit.

The top of C75W4-2 Root Rear Rib is not flush with the spar top and with the Spar Root Angle. It corresponds to the drawings. The spar end height is 80mm and the Root Rear Rib front end height is 91mm.

The first two pictures show the spar and the Root Rear Rib are…

The kit has incorrect the spar root angle. The drawing says the flange should be 25mm wide. Mine is 20mm. The predrilled holes in the root skin are too close to the edge. Zenith is thinking how to fix it.…
