I got bored doing detail on another thing, so I did this. It only took an hour or so.
As you can see it's too big to fit in the picture. The whole fuselage is courtesy of XML editing, normal fuselage parts blown up by four.
The landing gear is the same.
The rest is normal! The ONLY place you can take off from is Maywar Takeoff, well the only place I've taken off from at any rate.
There are probably other places.
This aircraft surprised me quite a bit because I put it into a Final Approach and it just flew, steady as a rock, until it stalled, no engines, no control surfaces.
I was fully expecting it to roll over and dive into the ocean, but it didn't.
The other thing is.... Giganticus can park under the wing of this crazy thing. 0.o

EDIT: Yeager is no good, Bandit is no good.
Avalanche is ok, Blue Glacier(?) is ok but you need to get on the power right away, Wright is ok.
Other places that are obviously too small should be avoided at all costs.

Also, XML editing is fun. I just realized why this performs as well as it does.
Four times the size does NOT = four times the weight, so those huge wings are lifting themselves + about 25 normal fuselage blocks, the engines and fuel.
