After the Market launch of the C1100,
The new Spanish govt. built after ww2,
Launched the "Proyecto de avión de transporte", a program to build a functional, long haul, all terrain /weather, stol cargo plane.

Casa, the only Spanish Plane manufacturer remained after the war(others were sold/gone bankrupt) and Counvas made a contract of partnership to buy 50 C1100, ripped off from their high tech instruments and shipped to Valladolid.

Casa implemented a all tail cargo bay.
To make Cargo operations easier, the Tail section could go up to 90°(ag2 +trim)

After the building, they found out that the Twin engine configuration didn't succeed in sustaining the plane in a stable flight, that resulted in the accident of the 3rd of May 1991,the prototype stalled, and crash landed, luckily, in an open field with no houses nor casualties.

So Casa implemented 2 other engines,that made the plane not stall.

Controls :

ag1: lights

ag2+trim:cargo tail

ag3 to ag8 nothing.

hope you like it, and also, i mentioned a french gunship version of the C1100.
i have a low end device, so idk if it would work with those many parts(im lucky that I've managed to build this without crashing).

Aniway, if you want to build the gunship version feel free, just post it unlisted, tag me, and ill write a description for you.
