Mig 31, Uneven number of main wheels
Looking at the photos of the MIG 31 it appears to have one mainwheel on the right and two on the left. Anyone know if theres a great design reason why its not equal on both sides?

No magic other than the camera angle
The wheels on the main bogeys are offset, the camera angle has merely hidden the outboard trailing starboard wheel.

A MiG chap told me its for operating from snowy/slushy runways, the offset is to prevent build up between the wheels which freezes at height then you have trouble getting the gear down.

Apologies first for a bit of thread drift, the front of the main wheel wells looks very much like a speed brake, similar in fact to the nose gear doors to the C130 and main door of the F-111.
My question is why have so much drag on T/O when for obvious reasons air speed is (and) height are the aim?
Or is the power of these aircraft such that its not an issue?
Just wonder as civie jets don't seem to have the proverbial 'Barn Door' hanging down on a very crucial phase of flight.

When you select gear up in the aforementioned F-111, the first thing that happens is the gear door/speedbrake opens up to nearly 90 degrees to the airflow (even further than the 'full speedbrake' position) - but any increase in drag is basically imperceptible.
