Throt/ Rud

[John Pavlick]

Ed,
 Sure, but you can only fly planes like that in SPA!!! (Or Sportsman). My
Super Kaos Jr. is set 0-0-0. Just a little bit of right rudder and up elev.
trim - still tracks down lines straight. I don't mix anything with the
radio - it's all done the old fashioned way!

  Think about having the trim and thrust where you don't have to do
either?????

    Ed,
     Don't think 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.
     If you think about what Chip described: Trim for straight flight at
full throttle, mix left at idle. Another way would be trim straight at idle,
mix right at full throttle. That's what I've been doing. Same difference.
