Well, you guys are confirming what I've suspected all along since I first learned way back when about what goes into designing pattern models.  And that is that there's way too much going on and anyone designing their first model can't really expect to come up with a world beating design on the first go.  Today's mixing radios can certainly help but in the end the model has to have the right stuff as well.  And there's a huge amount more to a world class precision aerobatic model than first meets the eye and calculator.
