Rudder/aileron coupling in knife edge?
Greetings,
After trying knife edge with my new World Models Ultimate 120 a couple of times, I've got a question about coupling between control surfaces. When I crank the rudder in, this model needs aileron and elevator correction to maintain heading. I'm assuming this is normal (I've never had a biplane before.....or a model with this much rudder authority), but what I'm wondering is how the rest of you handle it. Do you exploit the mixing capabilities of your computer trannies (which I'm about to play around with), or do you rely on the mixing capabilities of your brain? If you use the tx mixers, do you use a switch to turn the mix off until you need it (to avoid unwanted aileron or elevator input while on takeoff etc)?
