This is the CM-200, CM standing for Cargo Monster. It's 10 meters longer than the Airbus A400 and has a significantly bigger cargo hold. It also has a bigger wing surface area, way bigger power to weight ratio, smaller turn ratio and lower stall speeds than the A400, which would be it's main real life competitor.

It has 4 engines and 8 contra-rotating propellers, giving it a whopping amount of thrust, which it needs to do short take-offs and efficient flying at cruising altitudes. It also has a new tail design, existing of two vertical stabilisers and a mid mounted full horizontal stabiliser setup, giving it maximum stability and manoeuvrability.

The engines are mounted backwards for a better center of weight, and they are mounted upside-down to keep the centre of weight and lift aligned with the centre of trust. This means minimal inclination changes during throttling up and down.

This specific version is equipped with three cargo carts which can be air-dropped.

VTOL: Flaps angle
Trim: Elevator trim
Activate 1: Cargo bay doors
Activate 2: Release Cargo
Activate 3/4/5: Cargo parachutes (first cargo is 3, second is 4 and the last one is 5)
Activate 7: Landing lights
Activate 8: All other external lights

The aircraft is equipped with flares.

    @m16a2wm203 Yeah I agree, the flaps should not work haha. But they do, so for now I'm rolling with it. :P Thanks for downloading the plane though!

    The counter propellers are nice and you are right for cargo compartment circular shape is a pain. Still the flaps should be behind center of weight on a conventional airplane. This could result in a nasty stall.

    @m16a2wm203 Thanks for your comment! You are absolutely right, in the real world this would probably be the case. But in SimplePlanes it seems to work exactly as it should :) Also about the shape, I did this so I could make a cargo hold and cargo ramp. I'm not so skilled that I can make that in a circular shape, so this is how I had to do it :)

    Future you say yet the fuselage seems to look quite similar to Short Skyvan (we are talking about 1963), such design would have enormous trouble when facing crosswind. I don't know what are your sources for A400M data, but I doubt those are correct. Your competitor would be C17 I guess.
    Also what do you mean by better center of weight? Center of weight(mass) on your airplane is way too aft for such type of airplane which results in the fact that flaps have exactly opposite effect than usual, that is when you extend flaps, your airplane pitches up, for which you have insufficient trim to compensate the pitching moment. You can have center of weight in such aft position, but that would be usualy behind the neutral point or in here center of lift resulting in unstable flight characteristics. Also pulling the center of weight up doesnt make much sense on a high wing aircraft. Overall it looks nice, but looks dont fly.
