Harry, you crack me up. First off aileron differential does indeed work on models. To state that it does not just tells me you have not progressed into advanced R/C flying. Same goes for rudder application in a cross wind. There are several reasons why it may not work for full scale but does for models. I have stated time and time again to you well read full scale guys that flight characteristics between full scale and models is vastly different because of wing loading and power to weight ratios being so different. Others have not listened so i don't expect you to either. Imagine a world class R/C aerobatics guy walking up to Patty Wagstaff and telling her she is doing it wrong. Wouldn't go over very well I'm sure. I honestly don't see the difference between that and a full scale guy telling accomplished R/C pilots that we are doing it wrong. Some things work well with some models while not so much for others.
