There's really no such thing as an "outdated" plane. Sure, it's a bit old school but it will still fly. There are many people around that still build their planes and enjoy the building as much as the flying. Newer doesn't always mean better. Nothing says you can't update some of the materials used in the construction to improve the strength or to make a design lighter. I did just that on the Windfree I built and am glad I did.

I am still flying planes like the Paragon, Gentle Lady and Windfree, all of which are older than the Ninja.
