well, to each his own opinion I guess.
I can tell you I bet that the mechanical parts for all 3 helis are absolutely identical (too bad nobody made hop up parts for the Twister, which was released about 2 years ago ...)
You are right, they dont copy, its just rebranding
and as far as the sensor stuff goes: I hadnt heard about that until you posted the video, so I cant really say how it works, and the people in the vid dont say squat ...
So for those, I am looking forward VERY much to a lengthy review from you - if that stuff actually helps for anything(or if the best help is to not pick flying spaces that are too small for the skills of the pilot
As I mentioned before, no offense - but to me this is only interesting, because I now can continue a project that I had on ICE for about a year do to parts unavailability
