   Very nice! I want an electric plane! It’s nice that it is much quieter than an ordenary fuel engine and that you can shut off the motor now ant then. More of a “bird” feeling”. A fine flight. Perfect landing.

   I think the Aurora was the prettiest pattern plane ever flown. Sure, they ‘all look alike’ to most, but not me. Long live the Aurora!!

   I ment the torque of the individual/each motor not the cancelation.
   under the assumption that both motors run the same speed with the same prop (one right and one left issue): is the powerconsumption the same as for a single one at the same speed?

   Thanks for your interest.
   On the fall size yes they were if not a little more efficient, if you take out the extra complexity. There is no torque effect or at least very little with contra’s

   I would like to know a bit about the math of this.
   is it the same as a single prop with a motor twice as strong? is the torqe halfed?

   Hi
   It quite easy the back motor drive through the centre of the front motor. The front motor rotor sits on the shaft, on bearing. So it can rotate in the opposite direction. Take a look at my other contra motor video, it may be a bit clearer.

   i dont understand how this works. are the motors spinning in opposite dirrections. or some type of gears revers the other prop
