I’ve seen more than one Tiger with full fuel, 2 in the back, small cargo and then when one of the front seat passengers get in, sit on it’s tail. When this happens you almost always get a crease in the trim tab.
With the lighter engine of the cheetah this will be worse.
So, the solution is to have the two front passengers, stand on the forward wing walk while the back two get in.
