Hello
Some small details of the MIG-21:
Affects the landing gear. In the Eduard kit, an essential part of the landing gear is completely wrong and the corresponding components are also wrong. This concerns the so-called parallelogram, which ensure the vertical position of the wheel. The wheel is always vertical. They have a joint at the bottom of the chassis leg, just for this purpose. The torsion scissors sit above. The landing gear cover is divided into two parts for the wing. There are two approximately rectangular openings in the top lid. The joint for the retraction and extension mechanism also has the same pivot point as the parallelogram there. Please look at the pictures!
Happy modelling
