Creating a New Model

Turn on the transmitter and go to “Menu / Model / New Model”. Enter a name for the new model and follow the step-by-step wizard.

Note: Never assign the same name to two models.

Tip: To help identify models more easily when switching between them, it's useful to assign an image to the model (in the “Model Image and Colors” menu). You can download a suitable image from the internet or take a photo of your model. Save the image in the “Img” folder on the transmitter's memory in *.png or *.jpg format. The recommended image size is under 100 kB.

 

In this case, the chosen configuration includes:

• Wing type: two servos for flaps, two for ailerons
• Tail type: one servo for elevator, one for rudder
• Engine count: 1
• Airbrake servos: 2

 

Note: This configuration can be changed or extended with additional functions at any time.

• In the wizard menu “Function Assignment,” check whether the transmitter assigned the controls to functions according to your preferences. You can change the control assignments using the 3D button and the buttons below the screen.
• When prompted with “Pair the receiver(s) now?”, insert the bind plug into the receiver’s Ext. port and connect the receiver to power.

• Confirm the binding by pressing “Yes” (F5) below the screen, then remove the bind plug from the receiver. The new model is now created.

 

 

 

 

Reversing, Centers and Endpoints of Servo Deflection

Tip: Start by roughly adjusting the control surface deflections using servo arm/linkage ratios so that the entire servo travel is used. This also applies to the initial coarse alignment of control surface neutral positions.

In the “Menu/Model/Servo Setup,” set the direction, amount, and speed of travel for each servo in the model. Using the “Servo Balancer,” you can modify the travel curve, for example, to synchronize the movement of two servos throughout their range.

Note: Always begin by setting the neutral position of the control surface. Only then should you set the endpoints.

Max/Min: Sets the endpoint of the servo output, which may be exceeded under certain conditions (e.g., due to mixing with another function).

Max/Min limit: Sets the absolute endpoint of the servo output, which can never be exceeded under any circumstances.

Warning: Continuously monitor whether any servo is reaching beyond its mechanical limits. There is a risk of damaging the servo.

Delay positive/negative: For some functions, it is desirable to slow down servo movements, such as in this case for both flap servos. In the image, the downward movement has a longer delay time than the upward movement.

 

 

 

 

Dual Rates/Expo

For control functions such as elevator and ailerons, it‘s recommended to use an exponential servo deflection curve. This reduces the servo deflection in relation to the control stick movement near the center position, making the model easier to control without limiting the maximum deflections. The function can be activated in “Menu/Fine Tuning/Dual Rates–Expo.” A suitable expo value for elevator and ailerons is typically between +40% and +60%.

 

Note: For airplane models, we don‘t recommend using negative expo values.

 

 

 

 

Aileron Differential

Aileron differential (“Menu/Fine Tuning/Aileron Differential”) is a useful function for models with an asymmetrical wing airfoil. It improves the model's response to aileron input and helps prevent barrel rolls. The correct differential value depends on the specific model, but the downward aileron deflection should always be smaller than the upward deflection.

 

 

 

 

Trailing Edge Camber Adjustment

Adjusting the trailing edge camber (i.e., both ailerons and flaps simultaneously) upward increases flight speed. Adjusting it downward increases lift and reduces speed. A simple method is to use additional trims:

• Select a suitable control, preferably a slider or rotary knob, to control this function
• In “Menu/Model/Function Assignment,” assign this control as a trim for both the “Ailerons” and “Flaps” functions
• Use the “Trim-MAX” value to set the maximum deflection range for camber adjustment
• It’s recommended to assign a smaller deflection value to ailerons than to flaps
• The optimal up/down deflections vary by model, but typical values are around 2–3 mm up and 3–8 mm down

 

Tip: In “Menu/Advanced Properties/Sounds of Prop. Controls,” assign the selected control to the “Control” field and choose “Voice” as the “Mode.” The transmitter will now announce the control’s current position each time it changes.

 

 

 

Butterfly

The Butterfly function (“Menu/Fine Tuning/Butterfly”) uses upward deflection of the ailerons combined with downward deflection of the flaps to replace, supplement, or enhance the effect of aerodynamic brakes.

• Assign a control to the function; this can be the same control used for flap deflection
• Set an Offset value—e.g., with an Offset of 40%, the Butterfly function activates when flaps are deployed at 40% or more

 

 

 

 

 

Tow Hook

Procedure for adding a tow hook function:

• In “Menu/Model/Function Assignment”, use the F3 (+) button to create a new function, e.g., “Hook”, and assign a suitable control to it

 

• In “Menu/Model/Channel Assignment”, assign the “Hook” function to the next available receiver output

 

• In “Menu/Model/Servo Setup”, adjust the max. and min. servo deflection for the tow hook function

 

In “Menu/Advanced Properties/Sounds on Event”, you can assign voice announcements to the Hook function switch, such as “Hook secured/Hook released”.

Tip: Sounds on Event can be assigned to any control. They improve awareness and confidence during model operation. If the required announcement is not available in the transmitter's library, you can record it using the transmitter's microphone, download it from www.jetimodel.cz, or use a PC text-to-speech program. The recommended audio file format is *.wav and the filename should not exceed 8 characters.

 

 

 

 

Electric Motor Control

Currently, the throttle stick of the gimbal is assigned to control the flap and butterfly functions. By using flight modes, we can also assign motor power control to this stick. In the “Flight” mode, the throttle stick will control motor power. In the “Landing” mode, it will control the flap and butterfly settings.

• In “Menu/Fine Tuning/Flight Modes”, rename the default flight mode “Default” to “Flight”
• Set the delay to 1 second and assign a voice file to this flight mode (see “Tow Hook”)

 

Note: Each flight mode can have its own control surface settings. Setting a delay prevents abrupt changes when switching modes.

• Use the F3 (+) button to create a copy of the flight mode and rename it to “Landing”
• Assign a suitable voice file to the “Landing” flight mode
• Choose a switch (e.g. Sf) to toggle between the modes
• In “Menu/Model/Function Assignment”, create a new function called “Motor” and assign it to the P2 control (throttle stick, see “Tow Hook”)
• In “Menu/Model/Channel Assignment”, assign this function to the next available receiver output (see “Tow Hook”)

Switch the flight mode selector to “Flight” and:

• In “Menu/Fine Tuning/Butterfly”, change the Mode “G” (Global) to “S” (Separate)
• In the same menu, remove control P2 and leave the function without a control

 

• In “Menu/Fine Tuning/Function Curves/Flaps”, change the mode from “G” to “S”

 

• Press F4 (Curve) to open the “Function Curve” menu. Set the curve type to “Constant”, and set the “Point” value so the flaps are fully retracted

 

Switch the flight mode selector to “Landing” and:

• In “Menu/Fine Tuning/Function Curves/Motor”, change the mode from “G” to “S”
• Press F4 (Curve) to open the “Function Curve” menu. Set the curve type to “Constant”, and set the “Point” so that the motor is turned off

 

 

Digital Trims

When using flight modes, you can change the trim mode for functions between “G” (Global) and “S” (Separate) in “Menu/Fine Tuning/Digital Trim”.

• Global (G) trim applies the same trim setting for a function across all flight modes.
• Separate (S) trim allows each flight mode to have its own individual trim setting for the selected function. This means the model can be trimmed differently in each flight mode.

 

Tip: Use the F4 (tools) button to save trim positions to memory, view trim history, disable trims, or rearrange their layout.
