be very interesting to see your results. I had the chance to build and
fly the Abbra with ZDZ 40. I was able to comparare the same plane with
OS160 back-to-back. Clearly the ZDZ 40 was behind in power (or
power-to-weight ratio) when compared with the OS 160 when doing the
Master schedule of that time. I am sure that less fuel consumption
with less BTU content means less power. The Abbra with the ZDZ 40
was ~3-4 oz over 11 lbs. The OS 160 Abbra was 9.8 lbs. I am
not sure now what the new gasoline engines manufactures are doing to increase
the power. I believe that an improvement in the design of gas engines is
required to make it usable for
pattern. </FONT></BLOCKQUOTE></DIV></FONT></BODY></HTML>
