It might be the angle of the pic, but that fuse looks kind of short. A typical trainer with a 60" wing span should have roughly a 40" fuse. According to my excel program, a 72" wing would call for a 50.4" fuse, a 19.5" horizontal stabilizer and a 9" vertical stabilizer. It says a .45 will fly it. a .46 LA with a 11X5 prop would drag it around just fine for a trainer.
