Soviet Orbiter Buran 3D model

I wanted to know what are the physical differences between the US and Soviet Orbiters. So I started to model Buran

So far the main differences are:

Nose gear is further away from the nose.
No OMS pods
The wings on the Soviet Orbiter are slightly more forward.
The wing profile and leading edge is completely different, compare to the US Orbiter
The after the payload section on the US Orbiter, the rear section extends out slightly, on Soviet Orbiter, the 'rear' stays almost in line with the payload section.
Tail and rudders are different.

Good work!
Makes me wonder what the flight characteristics would be like, compared with the US orbiter.

Thanks :)

Apparently, the L/D ratio on Buran is 6.5, when the US Orbiter is 4.5. So glide would be better. Also, but I can't confirm this, the landing thresholds for crosswind and other factor were more forgiving than the US orbiter.

There were a lot technical with equipment that was not flown on the first flight. However, cutbacks and the cancellation meant that these could not be solved. There was a plan to add air breathing engines but this was an issue at hypersonic speeds in the wind tunnel.
