Try to look up some of my replicas, or better, high-end player's ones... They're really simple, once you know how to make them...

Tips:
*To inspect other's builds & know how they have done the build, take them apart one by one, & know how they place their blocks.

*If the part you want is nudged, & cant replicate it in your own build, put that part in your sub-assembly & open it in your aircraft by dragging it from the sub-assembly category

use fusalage blocks
