To practice, I can download the free Heli-X 5 Demo highly recommend as software - rarely so much fun at Heli flying practice had. With the Windows 7 USB Secker 32-bit plugged, can be installed by itself, plugged remote control, Heli-X started, adjusted stick, and off we went. There are 5 in the demo aircraft resulting in the difficulty increase ... DJI Phantom, Eceuril with paddles, Eceuril with flybarless, T-Rex 500 with CP, and yet something violent, 3D unfliegbares for experts.
I know the real MJX F47 and WL V911 ... I also highly recommend for beginners. 45 or 35 and by at least 100 crash still not broken. But FixedPitch helicopters are quite stable and thus to control simple. This allows you to practice the most basic direction control well.
With the cable and Heli-X can even practice the craschfrei, and, indeed, practice so you skip flybarless fixed pitch and the same with a CP heli get along.
What you can accurately with the cable transmitting what is now configurable at Heli-X, or to the J6 Fernsteerung, I have not found out, but the default settings rich first time to practice for the next few months.
Hope thus have only helped to Helisüchtigen Helieinstieg or Heliaufstieg.
