Default RE: roll coupling on knife edge - problem

BTW, it's flying day for the retired guys at one of my club fields. So I'm about to head out. I'm taking an alltime favorite, a WorldModels Ultimate46.

That little sucker is QUICK. And from day one, it had a very pronounced rudder couple. Lot's of pitch with any amount of rudder and some roll. Takeoffs and landings were a pain because adjusting your flight path with the rudder gave pitch changes you really didn't need. It's kewl advice most give about learning to fly the knife edge without mixes and you'll become a better flyer. You will. They are right about that. But ask any of them how they practice dealing with the unwanted pitch and roll they get landing. You'll probably get a blank stare in response. And then watch 'em land.

That little Ultimate got mixes worked into it's programming on the TX about the 2nd day it flew..... back in 2006, I think it was.

There is no shame in adjusting a model to respond to rudder with just yaw. And no glory from cutting the model up and rebuilding to adjust that rudder response instead of fixin' wid' mixin'.
