| maybe you have got this answered already...
rudder is controlled by turning the swashplate like aileron commands on a single rotor heli...with a catch
if you turn the front swashplate to the left, the nose moves left, if you turn the rear swashplate to the left, the rear swings out to the left.
if you want to pivot around the center of the heli, then the swashplates pivot in opposite directions (controlled by the rudder channel on a model)...so both swashplates must go in opposite directions to turn on the center of the heli
back to what I said earlier...you can turn a twin rotor a mix of these 3 different ways...if you want to pivot left on only the on the rear rotor, you feed left aileron and left rudder
.....if you want to pivot left on the front rotor, you feed right rudder and LEFT aileron...confused  its not that bad.
to go forward and backwards, chinooks move the front swashplate up and down (like a collective) you could move the rear one too or a mix of both...doesnt really matter how its done.
the gyro in the chinook models is usually put on the elevator because it is the most sensitive control. the rudder doesnt really need a gyro. they don't have any countertorque problems and are slow to turn.
if I was to build one from scratch, I would use two helis that have tube t/rs and pick a machine known for having strong crown gears....my biggest concern with my hirobo sea-knight was the belt tranny, which would surely slip if you put the thing through its paces...that and it is a heavy pig that I wouldnt want to auto it at any cost. |
