f) Checking the Tail Rotor Function

Before checking the tail rotor function, it is sensible to set the gyro sensitivity to the lowest value. this way, you can

recognise only the control movements of the transmitter at the tail rotor and not the control impulses generated by the

gyro.Forthis,turnthedialswitchforthegyrosensitivity(seegure1,item18)tothemiddleposition.

Figure 16

Since the main rotor, viewed from above, turns clockwise to the right, the fuselage tends to turn counter-

clockwise (to the left). To avoid this, the basic settings of the tail rotor are chosen so that it will compensate

for the rotating inclination of the fuselage even without a control command from the transmitter.

blades of the tail rotor are already slightly aligned to push the tail to the left (viewed from above) and thus

the fuselage tip to the right.
