Hello Howard,
          I rsponded to your post but having major hassles with Netscape mail out,
recieving ok I guess it never got down the fiber :-)
 Thanks for your (and others) input; I hear what you are saying been around and
around the same tracks myself. Too many ifs and maybees I think on the direct
drive approach power-rpm etc. Prop shaft & particularly shaft bearing and caseing
loads plus engine/prop (pusher config) resonances make me cringe just thinking
about it :-(  Better off even sticking with 2stk Rotax {:-0
Oz U/L experimental category 544kg is not much to play with for plastic
performance A/C.
Airframe, engine, fuel 80kg pilot, 80kg passenger(optional). I reckon it can be
done....just.
I don't want to go full sized Aus experimental, too many hassles & restrictions,
licensing, opperational proceedures, flight plans etc.  enforceable legal
requirements rather than good practices and emphasis on safe opperations.
I'm just hoping that the knowledgable 'lurkers' Paul mentioned realise that I'm
not a threat because I'm in Oz not on thier patch and I only want to make one for
my own A/C use. Maybe one of those who have done the single rotor thing will give
me some clues?
I'm still open to persuasion if there's a better way of solving my dilema  :-)
Thanks again for your input.

Harry S
