Taking it to the next level: Blade Nano CP X. A flybarless helicopter,
  collective pitch. And I bought a Spektrum DX6i transmitter which I can
  use for other models as well.

  What  a difference to my Nine Eagles Solo Pro V. :-) Not that the CP X
  is "better" or "worse". It's just completely different. The  Solo  Pro
  is  fixed  pitch and, most importantly, it has a flybar. This makes it
  snap back to "no movement" when you take your hands off the  controls.
  The  CP  X,  though,  has no flybar so it keeps its current flightpath
  when letting go the controls. This is very challenging, now, that  I'm
  used to the Solo Pro.

  The  Nano CP X is a very small helicopter, same class as the Solo Pro.
  This is brilliant! You can fly them indoors (no bugs or mosquitos) and
  crashes rarely harm them. Great for beginners like me. :-)

  In  another  6  or  12  months, I want to fly bigger machines, though.
  Something that can easily carry a camera. Isn't flying what  everybody
  dreams  about?  I  can't  fly  all  by  myself  but  I can fly a small
  helicopter with a camera. That's pretty close. :-)
