A few things quickly come to mind:

-Take note of the extra ribs installed on the front landing gear mounting - they are weak and break easily

-Build some covers over the wheel wells on the main gear to prevent debris from getting to the turbine inlet

-I made a tray on top of the existing tray so I could make a nice clean installation

-Put the CG on the wheels or maybe on the struts - makes the plane much easier to land

-Make sure there is no slop in the elevator linkage

-Use the jet-tech 4l fuel tank for the Scorpion
