Hello dgliderguy,

You are 100% correct, the model Corby does not have the same amout of angle in the wing dihederal as the full size. I buit 3 version of the model before it went to the factory, all of them had small changes in one way or another.
With regards to the dihederal the reason it was lowered as the model would show signs of pro - verse roll when rudder was applied in both level flight and in knife edge flight. Simple put pro - verse roll when applied makes the model roll in the same direction of the rudder direction in both knife edge and level flight, the first protype that was made had the scale dihederal and it did pro verse roll quite badly, hence the change to what it is now. Its all a bit of a compromise when you design model's and when they are used by the public it is even more important to get it as close to every bodies skill level. I do agree with you all the same that the dihederal is a nice feature of the full size.
