I have to disagree, the newer electronics packages are utilising more channels, the computer radios give all sorts of nice flexibility and mixing options which are really useful. They're also very cheap compared to the standard 4ch Futaba 2.4ghz set. Lack of analogue trims isn't an issue when you are able to alter your end points to compensate. You can still add fire buttons and such, or assign these functions to switches. With a basic understanding of how your more simple transmitter functions work then you can transfer this to the more complex radios, just have to read the manual!
