The main landing gear of MiG-3 retracted by rotating inwards and slightly rearwards.

The doors of each side were divided into five elements.

The main element of doors is solidal with the lower part of leg and with the wheel axis. It is connected to the upper part of the leg by two rods: they are guides allowing sliding when the shock adsorber is compressed.

Two upper elements of the landing gear doors were hinged to allow the main element to move during the compression.

The lower one is hinged to the main door element, the second one to the wing inside the bay.

The leg and inner face of doors are painted light blue, and this is coherent with wartime images.

Four images of two small upper door elements.

The images above are from the front side.

The image on the left is from the back side.

The image below is from the left side.

Note that there are two guide rods for each leg.

The main wheel disk.

On wartime MiG-3s, it was painted green.

The wheel tyre is similar, but not identical to wartime photos, and the disk looks slightly larger than those visible on photos, although the details look identical; this was probably done to fit with available tyres.

A rubber manifold covering the shock adsorber is visible.
