<DIV

However, fuel cost would make a difference if we could use gasoline.
After my experience, I don't think gasoline engines available in that time
were viable option for pattern for higher classes. However, it
could work for lower classes. I am not sure what gasoline engines
manufacturers are offering to increase power today. Gasoline engines for
sure are more reliable in the low run than glow engines. Another
issue, vibration of gasoline engines requires special attention but is
similar to the situation we have when using glow
engines. <BR><BR>Vicente "Vince" Bortone<BR><BR>-----

<DIV>The Cost for the ZDZ was more than the OS 1.60 by more then twice as
much. Right?</DIV>

will 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><BR>_______________________________________________
