<DIV><FONT face=Arial size=2>When I put in even more right engine thrust angle
on my big bird now I get 4 flights on peak rather than 3. before I
was leaning on the rudder much more and had some right rudder trim all
the time which was gobbling my batts.</FONT></DIV>

<DIV><FONT face=Arial size=2>both methods seem to work well to correct this

any negative effects these two trim methods create?</FONT></DIV>

about inverted / upright / right / left like that. It's all the same to
the airplane. Upright the slip stream hits the left side of the fin
causing Left yaw. For sake of argument: Right thrust will be used to
counteract this. Inverted, the SAME THING happens. Don't think right /
left in reference to YOU, think left / right in reference to the AIRPLANE.
When inverted the slip stream hits the left side (still) of the fin -
unless the motor suddenly starts turning the opposite way. Same thrust
offset ("Right") required unless the slip stream goes away in a push. Now
if there's right thrust, you need left rudder to offset the right thrust
which is trying to make the airplane yaw right in the absence of the slip
stream air on the fin. If you still want to think about it the
"other" way, remember "left" rudder when inverted will make the plane yaw
to the "right" (in reference to YOU standing there watching the plane).
Now I'm getting confused.</SPAN></FONT><o:p></o:p></P></DIV>

think about what Chip described: Trim for straight flight at full
