I have the default Blade mQX RTF, it was a gift from my dad and I love it. It is pretty difficult to maneuver even after extensive practice inside/outside( ~20 hours ), trim has always been an issue with the provided remote. It would seem that real controllers can do so much more than the default Blade controller that comes with the unit, which I have found extremely hard to trim and or control correctly. ( only two options... High or Medium controls... ) Where can I find more information about remotes that will work with this unit? Can they be upgraded/future proof to FPV? I am really interested in expanding this venture.
