Paul kudos to rob for having the courage to mention or suggest using an 'aileron To rudder mix' for certain airplanes. Its always been a subject that is very controversial and not really a politically correct thing to suggest in especially a beginners forum. But I totally agree with him there are some airplanes that mix will be of great benefit without making a machine destroying the pilots learning curve, something often suggested when the subject comes up.
Paul generally the aircraft types that will benefit most and there are always exceptions either way Are: Cubs especially Cubs, High wing aircraft and biplanes especially slower flying scale types. There are always exception for example the ultimate type biplane the mix would be pointless but lots of scale types and especially ww1 types and so on.
Paul the reasons of course as Rob described is whats called adverse yaw which is cuased by the ailerons and your Trojan is a type that the mix is not really necessary but definitely so for your albatross.
While what Rob said about full scale airplanes that pilots correct for this adverse yaw is true but what is not so commonly known is that most full scale aircraft do actually use this mix to a small percentage and it is done mechanically with springs and bands. Most all of the Piper PA 28 series (most all the low wings) uses this mix and virtually all modern high wing Cesnas also have this mechanical mix.
Recently I have been working with a fellow who purchased ten years ago a Top Flight Tiger Moth ARF from tower after learning to fly and it was flown with help form someone at the time but it Terrifyed him so he parked it. When I recently set it up for him it was typically just a tad to tailheavy when I tested it and certainly could benefit from some aileron To rudder so I set it up and buddy corded him and the difference was substancial. after some cord time he can now finally begin to enjoy that ARF he bought so long ago.
Agine Kudos to Rob!
