Hi,

I think your confusion has arisen because the 'computer' bit of a transmitter isn't to do with the frequency it transmits on, it's to do with storing the settings unique to each model.

The settings vary from model to model and the transmitter 'remembers' the settings you dial into it, like the dual rate percentage, the 'sense' of the channel (that is, whether it is working reversed or not), the exponentials, servo end adjustments the trim settings you set in flight etc etc.

I reckon the most valuable thing a computer radio gives you is the ability to set dual rates. This makes it possible for a novice to fly an aerobatic plane on low rates before they get more bold/experienced, and set the rates higher.

If you go for a non-computer radio, it'll only take a few weeks before you wish you had spent the extra small amount of money and gone for a computer one.
