How does this compare to the Potenza Aura 8 or the EagleTree Guardian? I'm interested but there is almost no information availble on exactly what this device can do. I've downloaded the PDF manual, which only included very general guidelines but no specifics, like what different modes can be programmed (Crow, Snap Flaps, etc. . .). Huge market in North America. Lots of pilots chattering about this device on RCG but no one really knows anything about it.
