A German built a fully functional Sukhoi Su-27 Jet.

You know we all sometimes fix things by our own hands. I also occasionally do some work to my car. But a German, Harald Huf, made his own Sukhoi Su-27 jet.

This isn't a still model, but a fully functioning RC jet. I can't call it crazy. Because being only crazy won't let you finish a project like this. I am not only amazed by his skills but also the support from his family.
