Of course they're pretty small at that point. Do you run any performance tweaks in your fsx.cfg file? I seem to recall something about a part radius that could be set in FSX as well, which would make objects disappear when they were smaller than x pixels on screen. That might have the effect you're talking about if it was set too aggressively.
My LOD_Radius is set to 4.5.
There is a tweak for FSX:SE called "SmallPartRejectRadius" which seems to do what you are describing. I haven't used it but sending a .pdf to your e-mail which came from a FlightSim.com forum item. I may try adding it and will let you know if it changes what I am seeing.
