<DIV><FONT face=Arial size=2>As pointed out, using right thrust and/or
throttle-rudder mix it is possible to trim adverse thrust effects of the
typical pattern plane for only one flight condition.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>I should also point out my design, the VooDoo
Express, requires no thrust offsets and is in trim in all flight
conditions and all power settings.</FONT></DIV>

<DIV><FONT face=Arial size=2>Throttle to rudder mix or right thrust
?</FONT></DIV>
<DIV><FONT face=Arial size=2>Both practices meet our needs, separately or in
combination. The most useful need for right thrust ( or right rudder ) is in
the vertical up line. The most apparent need is early takeoff. The amount
needed for takeoff, vertical up and straight and level ( upright or
inverted is irrelevant ) are each different and all are
nominally at full throttle . We can't provide the difference with either or
both methods.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>The reason we are happy with our trimming is
because the thrustline does not need to be highly accurate. We seem to be
unable to descriminate with an error of maybe plus or minus 0.3 degrees
??

<DIV>Finally, I had chance to read the last K-Factor (October). I
read an article Practice and Trimming by Scott Covey (District 7 column)
and it was interesting the information in regard 0/0 engine trust.
However, it does gives too much details besides that the results were
good. I remember checking Chip Hyde Scandalous at Nats. and I
don't think I could see 0/0. At naked eye it was evident that it
has right thrust. I am interesting in finding real feedback
from experience pattern pilots using 0/0 engine thrust.</DIV>
