the ground and then the plane was flown. Nothing spectacular to report</span>.<span
class="533220621-11112003"> The plane flew well. Still needs a little
more right thrust. Even running very rich the 1.10 would pull the plane
straight up with the "break-in" APC 14 x 11. The engine has YS Engine
Performance Specialties 90 degree header and muffler. I use an Hatori
black rubber diverter to keep the oil away from the bottom of the
fuselage. With this set-up you can keep everything inside the cowl.</span></font></font></div>

satisfied that the YS1.10 will be killer once it is run in. It was very
friendly from the outset and ran well even when set rich. I will run
the 14 x 12 and the 14 x 13 when it is full broken in.</span></font></font></div>

class="533220621-11112003">A comment on CG. I have had more e-mails on
this subject than any other aspect of the plane. The plane calls for
165 mm from the LE. I ran my 1.40 version at 175 mm and it still
carried a little up-trim. The latest plane was set a 170 mm and now
carries more up trim than the first one. I shall move the CG back on
both of them to see if it has any adverse affects and to advise on what
is a sensible rearward CG. </span></font></div>

<div><font face="Arial" color="#0000ff"><span
class="533220621-11112003">As it stand 175 mm (~6-3/4") works just
fine.</span></font></div>

<div><font face="Arial" color="#0000ff"><span
class="533220621-11112003">One trimming tip. After you land you often
find that you have beeped in a few % of trim here and there. If you
like keeping your main trims at zero% you will most likely the
electronic sub-trim or mechanical pushrod adjustment. It is hard to
reproduce the desired trim by eye or feel.</span></font></div>
<div> </div>
<div><font face="Arial" color="#0000ff"><span
class="533220621-11112003">A neat trick is to use two pins. Put one
pin sticking straight out of the TE of the aileron. Then position a
second pin sticking out of the TE of the wing. Line the pins up. Then
take out the stick trim-setting and re-align the control surface pins
with the sub-trim or turnbuckle or whatever.</span></font></div>

<div><font face="Arial" color="#0000ff"><span
class="533220621-11112003">You can be very accurate with this and it
is also very easy to do in field conditions.</span></font></div>
