It can be done.....when I crashed mine...I used 3/32 balsa.....but...instead of using the light ply with all the cutouts to reinforce the sides.....I used 1/16 plywood........stronger and lighter....

I also did not have to use lightening holes in the rear part of the fuse.....

I have been building.....flying...crashing.....and rebuilding since 1987.....si I learned long ago that there are cheaper alternatives to a lot of things used in modeling......

I say......GO FOR IT.......
