3ch coaxial is totally a different world from 6ch single blade woo. If you can hover a 6ch single blade rc heli, you can control a 3ch coaxial in 1 finger! If you can fly a 3ch coaxial and never touch any rc heli more than 4ch single blade or play well in flight sim, I suppose you even unable to get a 6ch rc heli up in the air. Or it can only stay in air for a couple of second. Just an analog!
