I'm not fond of them myself. Paper doesn't hold curves particularly well, and I generally don't see paper models as very convincing no matter how well they're built.
There's also another issue of print registration. Just as decals in a plastic kit that are out of register are a nightmare, the entire color areas on the paper you cut the components out of on a paper model being out of register is even worse as there's really nothing you can do about it.
I'd say keep looking for a non paper kit of the Wright flyer, you may have to look to more obscure vacuum form or resin kits, but I'm sure a 1/72 of it is out there in something better than paper.
Additionally, if you think cleaning dust off plastic models is a chore from Hell, don't get into paper models, they're 10 times worse to clean.
