They're more useable than dual rates on my old plane. One switch. Up is full 3d rates (and higher expo, a little spoiler mix, etc), middle is normal 'high' rates and down is low rates (for landing and so fourth). On my old radio each surface had it's own switch so you had an aileron high/low rate, an elevator high/low rate, etc. 3 switches to manage, and my basic setup was low rates were as high as I could get them and still fly the plane and 3d rates were, well, huge. Now with this radio I can have a low rate that isn't as touchy for takeoffs and landings. Maybe this will be a moot point as I just setup the thing this weekend and probably wont fly it until Sunday if the weather lets up but that was one gripe I had about wanting 3d rates then you needed your low rates to be as much as you could still fly with and on landings and some straight-line manuvers I would wish for some lower rates. Just my 2cents
