This one has a Rotax 912UL on the front of it. I’m sure that contributes a lot

Rotax 912UL
My old 4-1050 had and empty weight of 650 with a 912UL. The Mangy Fox (4-1200) with all of its extensive mods, reinforcements and a big bore 912UL is only 700 empty.
The first thing to address is *why* the plane has a 750# empty weight and what can be done to put it on a diet...
There isn't 200 pounds difference between a 582 and a 912. More like the 912 should add 50 pounds. You should still be somewhere in the 610-620 pound range. There is 150 pounds of extra weight there somewhere. On the model 1-4 but especially the 1-4/1050 the key is a light build.
