Hi, fellow rotray enthusiasts.....I was just surfing the web for 13b related
items, and came across this website   www.aerota.com/pages/contact.html
They show their single rotor, twin rotor, triple and quad rotor rotary
engines, claiming some pretty high power outputs.  Has anyone else heard of
them, or have I just been living in a cave too long?  Thanks for your
replies. Paul Conner
