stolen idea from Gilbert Magill in 1954
-
There is no torque caused by the rotor, the tail rotor acts only as a rudder.
-
is the fuselage made of wood?
-
why is there still a tail rotor? Because there isn't a rudder?
-
@jimday666 hahaha god flies without rotors
-
How long could you stay airborn ? and what's the fule consumption ?
-
Germany was using this technology in WW2. It's incredible and interesting. I thought the design made no torque, but the tail rotor on this copter means that's not the case.
-
absolutely amazing!!!! didn't think you were going to take off initially
-
On second thoughts - blade tip propulsion = no torque! Hover rotation by rotor shaft clutch? I've got to get one ...
-
As an ex-helicopter pilot, this looks the sort of thing to get me in the air again!
Some comments: Cyclic passes through the pilot's forward vision. A coiuple of linkages will pass it underneath in the next model I assume.
No pedals? Torque altered by rotating the cyclic?
One turbine failure would just reduce radial power, not un-balance it.
Standard auto for both failing, I assume.

DF1 Test: -3 Celsius (Dust from the rockets is steam until the rockets burn after several seconds 100% of the H2O2).
