oh crap, he has the old original sagging landing gear system, there is a completely upgraded main and nose gear system for this jet. The cylinders have a locking mechanism in the cylinder so once the gear is down / up it cannot sag. It also puts the nose gear cylinder in a better position. I would strongly consider getting the new gear (main gear themselves are the same, just different cylinders) and new hydraulic system before going any further. The original gear is one of the main reasons that most of the Mig's out there never flew.
