RC Avatar-like twin rotor heli from flite test


What do you think about that? It is similar in concept with the helicopters from the movie Avatar, it uses differential thrust and independent tilt for each rotor. It doesn't look very stable but this looks like a very primitive prototype. Maybe it has the potential for something quite cool.

    Same board, much more stable...has been done already.... :-)

    What I really want is an easy way to make some good blade guards! I wonder if these are mainly cosmetic?

    Using a KK. Just add some window dressing and should look just as good and can fly fairly well.

  • Does anyone have the link for the software they were using?

  • @ robert: not more complicated than in a normal helicopter or quad ;)

  • 100KM

    I'm not sure if it's the copter that's unstable, or the thumbs that are unable...

    Anyway, the look on the dude's face is priceless when the Joshes trash his gunship.  Feel sorry for him though.

  • Not sure if you're aware, abut a guy on RCGroups builds these twin rotor machines and they actually fly quite well. There's some complicated physics going on.



  • It still looks cool though.


    Face it, it would be fun to take out to the park on a still day.

  • In the movie, the fuse stayed horizontal and the fans tilted, as you would want. In reality, torque canceled out but was very stable as two opposite forces. This would have required cyclic pitch control, witch we don't have. If it's going to be a pendulum the it needs to be one, not as a negative. Not enough hang glider like, witch was its only hope, to overcome the counter-torque stability. Failure it is.
