Setting The Digital Trim - Reely 4-Kanal-Fernsteueranlage 2,4 GHz Bedienungsanleitung

13. Setting the Digital Trim

The trim mostly serves to correct the slight inclination of the servo levers due to the interlock and the connected ir-
regular control movements. Additionally, there is the option to adjust the model in operation precisely, e.g. if it is not
flying straight although the control lever is in the middle position.
Then the linkage or rudder rods must be adjusted so that the trim has its original value (90°-range between servo lever
and rods) again and the model still runs straight.
The 4-channel-remote control has a digital trimming with which the four control channels can be individually set with
a trimming button (also see figure 1, items 4, 6, 12 and 14).
The trimming buttons are assigned the following control functions:
Trimming button 4
= elevator servo at the receiver output 2
Trimming button 6
= aileron servo at the receiver output 1
Trimming button 12
= rudder servo at the receiver output 4
Trimming button 14
= throttle servo at the receiver output 3
To check the setting of the digital trimming, first switch on the transmitter and then the receiver. If a trimming button
is moved to the side or up or down and held, the transmitter will emit brief signal sounds in a quick sequence and at
different tone heights. The servo of the respective control channel will change the position of the servo lever in small
steps. When the end of the trimming range is reached, a longer tone sounds and the signal sounds then go out. The
servo lever will no longer remove then.
If the trimming button is then deflected in the opposite direction and held, the signal sounds sound again and the servo
lever turns back to the middle position step by step.
When the middle position of the trimming range is reached, the remote control will emit two slightly longer signal
sounds at the same height.
Now set the middle positioning of the trimming in all four channels and install the servo levers so that they are at a
90° angle to the rods. Since the servo levers and the servo axis are interlocked, very small inclinations of the servo
lever cannot always be avoided. In this case, the trimming of the respective channel must be adjusted slightly from the
middle to return to the 90° angle of the servo lever to the linkage rod (see figure 8).
The set trim value is automatically saved in the remote control and is retained even after switching it off and
on.
When using the electrical model with an electronic motor controller, the trim for channel 3 also needs to be set to the
middle value.
