Zn-Line Alliance trimming question

[Mark Hunt]

I have a question regarding pitch mix with rudder.  If you mix some up with rudder, won't it appear when trying to wind/yaw correct when flying inverted?...causing the plane to drop the nose?

I wondered about stall turns also, but I guess the airspeed (nearly zero) would nullify any elevator deflection while using full rudder.

  I have flown several Alliances and all of them needed some pitch mix...Specifically they pitched belly with rudder. And to be quite honest most of them pitched more than I would like...BUT When this was mixed out they were extremely great flying models. 

  I would setup a curve type mix for the rudd-elev mix....This way you can mix out the coupling at different rates depending on the amount of rudder deflection. I usually stick 3 points on each side...Say 1/3-2/3-full rudder stick...

  Then go out and fly it and set the mix value for each rudder deflection. It works well. Some people think the model is trimmed when they get their mix to zero. Personally I don't really care what values the mixes are...the question is do they interfere with other things.  My experience with the Alliance is that when its mixed out properly it flies extremely well and you don't see it.

  From the sounds you are happy with CG, up and down lines so mix it out properly so that at any rudder deflection its properly corrected and you will never see it in flying it.

  Good Luck with it
