thanks for the help. these are the missing parts planes.
and missing parts for each ship:
and 2 new problems:
the space plane cockpits, for i know like kraken or stall class space plane cockpit, can not view or EVA kerbals but can transfer them to other parts. in the pic below, that was kraken class space plane cockpit whose capacity is 10, and i put 10 kerbals in it. there are only first 3 kerbals are shown at right bottom corner. (no letf or right arrow to swap kerbals so u can only see these three)
the plane spawned on runway is off ground, like pic shows. i wish it can be spanwed at lower position so the plane is not damaged because of hitting on the runway.
i am not so sure weather other mods cause these problems, i will try the game with OPT mod only later.
