And it still doesn't let you modify your differential throws on the elevons
for clean rolling motion; you'd have to do it manually.

Personally, I think a computer radio is essential for (relatively) exotic
control surface planes, like the Samurai.  Without it, you spend many hours
mechanically adjusting wheel/horn angles to get a 'correct' flight path.
IE, on the Samurai:  If your setup with a mechanically controlled differential
does barrel-type rolls when you crank the ailerons only over, you'll have
to fiddle endlessly with the mech differential.  With a computer radio,
you can do it electronically, and practically adjust it as you fly; or
at least, have it set up and flying well within a couple of hours.

Besides, to us techno-geeks, computerized equipment is a must. :)
