Personally, I'm not a fan of touch screens. (And no, I don't own a smart phone...or any cell phone for that matter.) Up to now, the RDS8000 has been as "complicated" as any radio I had ever hoped to use. Which is to say I hoped never to have to use anything more complicated. But the prospect of flying bigger and more complex models (though I''ll never be flying anything other than WWI other than for practice) makes a few "fancier" features like throttle curves appealing.
