Yeah on the other Dx's a plane is basically bound to a memory position. The transmitter won't operate the plane if the wrong model is selected. It is what they call model
match.

Another major advantage to the computer radios is being able to adjust the dual rates to your liking and having expo.

The Dx5 I think has 75% and 100% on low and high rates with no expo.

75% may still be really twitchy for low rate on some 3-D or very aerobatic planes, especially without expo.

Expo is kind of like variable rate steering on a car, less sensitive near the center while still giving full travel at full input.

The Dx8 has 3 levels of dual rate, which can be set to 3 separate switches so you could have elevator on high rate and ailerons on low, for example. Or you can choose to have all three channels on one switch.
