Default Hirobo electric Chinook question

This is the Hirobo tandem rotors Chinook:

It seems to be electric.

Both rotors are engaged to the same gears, as it can be seen when turning at lower speeds, or I am wrong? If so, then how does the heli change heading? Does the rudder channel work on the gyro to make the heli spin?

Thanks
Robert

Yes, they are synchronized through the transmission. Bad bad things happen when they de-synchronize.

As for rudder control (yaw) there's a pretty complicated electronic mixer used for those things but the end result is, when you give left "rudder" the forward head applies a bit of left cyclic, and the aft head applies a bit of right cyclic, and the result is the heli pivots on the yaw axis.

Now, do you have any idea about the price?
