Also, try side slipping any of the cessnas or the pa28. It seems that in this flight regime the rudder seems to lack authority, at least compared it to the 150's and 152's I've flown where you need quite a bit of aileron to counter the opposing roll of the rudder when the controls are 'well crossed'. Is this the case or is side slipping a particularly tricky thing to get right in the FDM?

However, I can sit at minimum power with the brakes on in nil wind and rock from one main wheel to the other using the ailerons. I can also lift the tail off the ground at minimum power. I'm not sure if that is a side effect of what you've done, but I'm sure that shouldn't be the case :-) That shouldn't be from my change -- can you do it with other YASim planes?
