The ability to store the trim settings in the computer has been around longer than the "digital trims"

The Futaba Super 7 series specificly... (average of about 15 years old... some of these radios are approaching 20 years old now) has the anolog trim levers as with a non-computer radio... and has the ability to remember where the trim was... so you can just press a couple of buttons and store it, then recenter the trim levers. (and... all planes in its memory can be flown with the levers centered for normal level cruise.)

I see an advantage to anolog trims for in-flight trim changes in different flight modes... a few clicks up-trim at take-off and you can take-off hands off the right-stick as long as there isn't a strong cross-wind to deal with. The analog trim on throttle is great... so you can have trim and stick down for engine kill, trim center and stick minimum for normal idle, and trim full and stick minimum for engine start.

No matter if you have the digital or the analog trims... you SHOULD readjust the mechanical linkage to center the trims, centering the SERVO for normal level cruise.

Computer radios can make you lazy about proper control system setup. Getting lazy about that can cost you an airplane.
