<P class=MsoNormal><FONT face=Arial size=2><SPAN
style="FONT-SIZE: 10pt; FONT-FAMILY: Arial">I’m fairly new to pattern flying.
I’m considering to buy the Focus sport and want to “keep it simple” with the
engine. I know the Focus was design for YS 110 but for cost/ simplicity
reasons i am considering the OS 91 FX or the OS 120 AX. In the OS web site
they claim that the 120AX is 20% more power but when I compare efficiency it
looks like the 91FX wins. Its 6% more efficient in power to Wight and 16% more
in power to displacement. Am I missing something? Practical RPM misleading
numbers? What would be your recommendation?<o:p></o:p></SPAN></FONT></P>
