8.2 Swashplate: direct cyclic feed forward (Dial 2)
Turn dial 2 clockwise to increase the swashplate’s direct cyclic stick feed forward. This is the part of the stick
input that is going directly to the servos. If correctly adjusted, this relieves the control loop which will work
more eciently by only having to make residual corrections. Factory setting of the dial is horizontal which
provides a good setup in most cases.
Increasing the direct cyclic feed forward will cause more cyclic stick input going directly to aileron and elevator
on the swashplate. Decreasing the direct stick feed forward will do the opposite.
If the direct cyclic feed forward is too high, it will over control your cyclic input. The control loop needs then
eventually to steer back. Even though you get the impression to have a more direct control, unwanted side
eects may appear, like pitch backs on cyclic stops and imprecise fast forward ight.
If the direct cyclic feed forward is too low, the helicopter will feel softer, slower and less direct. The optimal
point depends of many factors like blades, servos, head speed, size and mass of the helicopter.
At delivery the dial is in the middle which should be a good starting point for most helicopters.
8.3 Tail dynamic (Dial 3)
Turn dial 3 clockwise to increase the tail dynamic. Turning dial 3 counter clockwise will decrease the tail
dynamic. Factory setting of the dial 3 is horizontal which provides a good setup in most cases.You have
to make sure the maximum possible tail gyro gain has already been determined (see section 8.4) befo-
re adjusting the tail dynamic.
Increasing the tail dynamic will lead to harder stopping behavior and more aggressive response to tail stick
inputs. If the dynamic is too high the tail will bounce back shortly after a hard stop and feel spongy
when making fast direction changes. If the dynamic is set too low the tail feels dull and stopping might be
too soft. Ideally the tail should stop perfectly to the point without making any apping noises.
The direct cyclic feed forward does not aect the maximum rate of rotation! If the helicopter turns
too slowly, you should check the settings of the swashplate limiter in setup menu L, change the
control behavior in the parameter menu at point B, or increase the servo travels or “Dual Rate“ setup
in your remote control.
