  • Could it be that a single rotor solution would be much less complex and much cheaper?

  • That's sort of my opinion on it too.  It's an interesting concept, but it just doesn't seem like a great solution to the problem.  It seems like a tandem rotor heli, or a coaxial is just a cleaner solution to the problem.

  • That's an interesting approach and it makes sense.

    I guess I don't see what they're trying to do here.  I feel like they're making something for a problem that doesn't exist.     Great research, but if you're going to market something (and they clearly are), why not market something that actually has demand.   Right now they've built a complex mess that other platforms generally just do better.  

  • I looked at this thing a while ago.  It's interesting, but I don't think it's the best solution to this problem.  This makes more sense to me:

    Or there was another one I've seen, can't remember the name, but it's a single main rotor, but with two anti-torque rotors.  The AT rotors are mounted on the sides, not the back.  They push in opposite directions in a hover, to counter torque.  But in forward flight, they both push forward, just one side more than the other.

  • Correction, the site says 1 hour flight time, and it looks like they're using a lipo powered brushless on the front motor.  Maybe the flight time works to be about the same, but I don't know why you would pick nitro over a gasser.
