Sure will, when I weigh it. I started rounding off some of the surfaces last night. The sanding is going to remove measurable weight. I may seal and paint the nose of the fuse to resemble the aluminum cowls on many planes and only cover the wings and back of the fuse. Bent up my own tail wheel strut and will construct my own lightweight wheel.
The instructions say .40-.45 engine but seem to inffer that a .45 would be better. The Webra is lighter than many .45 engines and some .40s yet at the top of the power heap in that size class. 6.0 lbs would wing load at 23 oz/sq ft while 4.5 lbs nets a 17oz load.
