Who likes flying helicopters? I'm like the worse at flying the mini-copters in Rust so I'll have no chance with this one!

UPDATE: You'll notice the updated mesh in the first GIF image. There wasn't much work needed to change the design to the new specifications. I planned the model in such a way that changes to any of the sides shouldn't affect the whole mesh; by separating the mesh into chunks (by this I mean the front paneling is a separate element to the rest) i could just delete it and remodel. The texture was quickly done by creating a smart material from the material I used for the original corrugated panelling texture in substance painter, then I just remade the signs.

There was a drawback. Because the new geometry is larger in scale, it also had to occupy the same UV space, which meant it would have lower texel density. But it's a trade-off for a quick turnaround. The alternative would be to re-organize the whole UV, re-bake, and then to texture again, etc. No thanks.
