RE: C160 transall build
As light as the C-160 is i guess a grass drop would work, but the fiberglass fuse would have to be reenforced and that would add some weight. Its very strong as a round shell , but cutting the rear cargo hatch would weaken the tail section a lot. But it would be a neat Item to taxi out with the ramp down and close it for take off and do a flyby with it open. hoping to get out and fly mine this afternoon some if the weather cooperates
