I got forwarded this link a couple months back and I thought I would share it with you guys. I know there are a lot of people that don't know how a rotary engine works(not here obviously). It also has a lot of different engines, some I haven't heard of. Well enjoy...

good find...how much fun is your hatch?

 

It's been sold for a couple years now. It was a blast. 2200 lb. 13.1 @112

 

I thought more people would find this interesting than just one person.
