Original

The Kawasaki Kx-03 was a Japanese project for a massive 500 ton flying boat, it was intended to haul supplies across Japanese territories, the plane ended up having a length of 162 meters long, 35 meters tall, and a wingspan of 180 meters, it was powered by 12 turboprops and 4-6 jet engines, all mounted above the wings.

In this SimplePlanes version though, the scale is way off as it's only... 113.5 meters, had a wingspan of 126 meters and a height of 28.3 meters, well it's basically 70% scaling, it had 12 propeller engines each giving 1870hp, and 6 jet engines, it can go up to 150km/h, and you can disable the control surfaces, so you can operate the guns.

And a note, for some mobile users, you'd need a bit of patience using the editor with this plane, the plane has been upscaled so much it literally froze the editor for a few seconds while trying to do basically anything, seemingly this has something to do with my device's 3gb of ram, as when it froze, the CPU usage hovers at only around 20-30%, on my laptop on the other hand, the editor works just fine (albeit there's a significant increase in loading time when entering and exiting the editor), and that one's got 8gb of ram, so yeah, don't worry about overall performance though, it should run just fine.

Controls :
Ag1 : top and rear guns
Ag2 : right side gun
Ag3 : left side gun
Ag4 : front gun
Ag5 : change control input of the wings and horizontal stabilizer (change roll to VTOL, change pitch to trim)
Ag7 : lights
Ag8 : enable/disable control surfaces
Control guns with pitch and roll

Takeoff procedure :
Full throttle, keep steady until 65km/h, begin pitch up and hold at 5-10° AOA, it'll slowly lifts itself out of the water, for turning it's best to use the rudder than the elevators.

Downscaled version

This is how big a portion of the wing is next to an F-14
