<DIV style="FONT-SIZE: 12pt; COLOR: #000000; FONT-FAMILY: Arial">Correct. 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>----- Original Message -----<BR>From: CHV69@aol.com<BR>To: nsrca-discussion@lists.nsrca.org<BR>Sent: Sunday, December 13, 2009 8:11:24 AM GMT -06:00 US/Canada Central<BR>Subject: Re: [NSRCA-discussion] This email list is flawed in my opinion.<BR><BR><FONT id=role_document face=Arial color=#000000 size=2>
<DIV>The Cost for the ZDZ was more than the OS 1.60 by more then twice as much. Right?</DIV>

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>_______________________________________________ NSRCA-discussion mailing list NSRCA-discussion@lists.nsrca.org http://lists.nsrca.org/mailman/listinfo/nsrca-discussion</DIV>
