That's exactly why the discs are there, to prevent air from spreading over the rotor and create lift.

As the engines are to be placed just in front of the inner sections of the front rotors, most lift will probably created there.

By the way the spinning of the rotors control the lift. If rpm is low, less lift is created ergo if rpm is up more lift is created. I figured with four independent rotors and a rudder, one can control the aircraft in all three axis.

How are you powering your rotors?

Ehm, no...maybe a future version? I'm worried about the weigh. Think the motors plus the rotors will get too heavy and the spindly undercarriage will collapse.

In the what-if universe, a weak-looking undercarriage may be very strong (titanium matter or other, top secret…) ;D

Sorry Dave, I wasn't clear.  I didn't mean are you motorising the model, I meant how would Rockwell power the rotors on the real FAR-X?

Ahw, right! understood....

I was thinking about putting electric engines in the rotors. Electric engines are able to spin really high rpm's, weigh is depending on the type of engine (was thinking about coreless engines for their ability to accelerate rapidly, lighter in weigh and low torque). Electric power will be supplied by an apu just below rotor assembly and control of it all by fly-by wire...

That's what I was thinking.
