I am not a fan of the Tower 'ultimate combos' because they often include items I would not choose. Sometimes I think they put in whatever is overstocked.

I didn't read all of the posts in great detail so your question about computer radios may be answered. The primary advantage, in my mind, is multiple model memory. That way the settings for each model are stored so you do not have to make a lot of changes in order to fly a different one.

The programability for setting servo throw, exponential, mixing channels, etc is very nice to have but not an absolute requirement. The model should be set up mechanically as close as possible and radio programming should be for fine tuning.

Many times getting 7, 8, or 9 channel transmitters gets more model memory (more planes) in addition to more features. Features can be confusing. The manuals for most popular transmitters are available online so you can review them.

While everyone has a favorite (sometimes to the point of bashing all others) I believe Airtronics, Futaba, Hitec, JR, and Spektrum all have some very good products. Some of the lesser known brands are probably fine but sticking with the 5 listed means you can likely get answers to questions pretty easily.
