And so what! The engine certainly would be more modern. I just had some excellent fun flying in a Piper Cub on Sunday, it's about 3 times my age. Planes are not like cars, entire chunks of them are replaced on a regular basis materials prone to rust and similar corrosion aren't normally used.

It was my first time flying such a primitive old plane and honestly I hadn't had such fun since my first solo. I was walking round with such a grin.

Old planes aren't bad at all. They are tried and tested, meanwhile this design doesn't exactly look as modern as a Diamond or similar cheap to run glider-come-airplane so it's hard to be excited in all honesty.
