Good point Jim....... simplicity has been the main force behind my love of the iFly. I think I have only peeked at the old manual once to verify terrain settings. Other than that the unit is very intuitive.
Good case in point; my cousin flies my Arrow and he doesn't like the iFly, preffering his 4flight and an ipad. At times he has been pretty vocal about it and I just let him vent and remind him he can still use his ipad. I have noticed lately that he isn't fussing as much and I am seeing his last flight on my iFly more and more often.
