        Paul,

        The Spitfire was supposed to have gained 20mph with the
installation of ejector type exhaust nozzles.  Does this have any
relevance in the speed range of homebuilts. (That is getting to be quite
a range).

It won't be long before we see some rotary engine powered airplanes
going 300 to 400 MPH IMHO. Perhaps sooner than I think if R-Beat 900
HP turbo three rotors work.
