Ok its safe to say that the people that think the K4 is hard to fly or ez mode are in denial
while these comparisons are entertaining and graphically displaying them interesting... I think we all have a fairly decent idea of the planes' (assuming you've taken the time to fly them all) relative performances.
There are just too many variables to try and actualy quantify the unquantifiable. Ya know, on any given sunday...
Here's an easier spin on EZ vs Challenging... if it's a ride you're having fun with, it's EZ, if not, it's Challenging.
