The anti-torque pedals in a helicopter are used to keep the heli from rotating from the spin of the rotors (it controls the tail rotor)
Reduce collective will reduce the lift and the helicopter will begin to descend. Reducing the throttle will also reduce the RPM and result in descent of the helicopter. With less torque, the helicopter will begin to spin so the rudder pedals will have to be adjusted to reduce the amount of tail rotor thrust.
The pilot uses foot pedals and a hand manipulated stick.
You change the tail rotor pitch with the pedals. You can also use the cyclic and move in another direction, which will tend to cause the fuselage to align with the new course.
You can connect any pedals of any brand. Its best if you seperate single pedals away from multi pedals.
How fancy do you want them to be? Cheap pedals are die-cast. Expensive pedals are machined.
