Weighing in at over 620 tons with a wingspan of 120 meters, this is on the very edge of my computer's capabilities.
take off at 70 m/s, stalls at 50
only action group is for the brakes.
I'm impressed i managed to make it a functioning float plane at it's current size. there is absolutely minimal roll control, be warned.
Use vessel mover or other means to move it off the runway, the wings clip the buildings.
