Hi Andre,
I agree with "dubd" 1/5 pilot will looks too smal, 12" in 1/5 scale is just 150sm height - too young pilot ore dwarf
But there is some small problem with 1/4,5 pilot (7" - roughly 180sm height) to seat him in cocpit not enough space for shoes (under desk).....There two ways: cut and rebuild cocpit ore put pilot without shoes...I will follow the second way.
Kind regards,
Sergey
