And now for something completely different...
The XF5U Flying Flapjack
Weird plane with great theoretical potential, but the Navy wanted jets.
Props far outboard to counteract wingtip vortices.
Modeled in blender 2.79b on drawings from on-line.
Modeled in full dimension, then scaled to 1/100 for the .stl
Scale by 35% in your slicer to get proper micro-armor size
Props are huge...
17mm diameter in 1/285 scale.
( make with thin clear plastic sheet
