Hi Paul - I am a licensed pilot. I fly strickly for fun and am currently
   thinking about building a home built Helicopter (maybe a kit) . I am
   very
   interested in the Wankel Mazda rotary engine for this project and can't
   believe that I haven't been introduced to the concept before now . I
   have heard
   about rotary for years but, had always assumed it had pistons of
   some sort
   (simular to other reciprocating engines). Please add me to your
   Rotary engine
   newsletter "Subscribe" - I am looking forward to my first letter . Thank
   you . db / Wichita Falls, Tx
