Adjust the amount of rudder movement
Interface path: WFLY → [Model Menu] → [Winglet]
This function is used to adjust the left and right rudder of the model winglet. The winglet is
used to reduce the induced drag caused by the wing tip vortex. (Winglets are vertical or angled
extensions at the end of each wing.)
The winglets can significantly increase the wing's aspect ratio without increasing the structural
stress and weight of the wing. Although increasing the span is also able to reduce the induced
drag, it also introduces parasitic drag and requires more power to support the weight of the wing,
which results in no overall savings. The winglet can help solve this problem, it increases the aspect
ratio, but does not increase the wing's wingspan.
In the "model type" selection, the main wing type is selected as "delta wing", and when the tail
type is selected as "winglet", the rudder angle of the two rudders of the winglet can be adjusted at
this interface. (Applicable only to models with one servo on each side of the rudder).
●
The amount of operation of each servo can be adjusted separately. (For the connection method of
the steering gear, please refer to "Servo connection in different model categories")
● When the connection causes the mixing direction to be reversed, it can be adjusted by changing the
polarity (+/-) of the action amount.
● When the amount of action is too large or the rudder is repeated, the servo may not respond. Be sure
to confirm the actual movement of the body when setting.
* Flight conditions: Set the "Flight Conditions" control switch in [Model Menu] → [Condition]. Switching
is performed by switches, and function settings are made separately.
