Using the Wizard

In the Start menu select “Create new setup.” After you receive confirmation you are automatically led to the next step; “Receiver.”

Select the receiver to be used with your VBar. The default setting is “standard RX hookup.”

Tail Rotor Gain
Note that with 5.0 Express the tail rotor adjustments are carried out exclusively in the transmitter. For this, use a suitable channel with dial, slider or switch in your transmitter. For use with a standard receiver, a separate patch wire is included with your VBar. If you are using receiver satellites you need to assign a channel for setting the tail rotor gain. Check functionality. Should the display stay at 64 % (default), assignment is probably wrong.

If you are using a standard receiver, the speed controller is connected to it as usual. If you are using Spektrum satellites or single-line receivers (Rasst, S-Bus, Jeti), the ESC is always connected to the port “Collective/ESC.”

Adjusting the Transmitter
It is necessary to set the TX signals to the correct directions, center, and end positions. This is done by using the transmitter’s sub trim menu to zero all centers for all channels on the VBar setup software. The ATV menu is used to adjust all channels to 100% at full stick deflection and the servo reversing is used to change direction to correspond to the correct direction in the VBar software. Once this is done, you need to save the center positions to VBar by clicking the button “set center.” VBar will perform a cold start and reinitialize. When finished, the V will stop blinking.

Sensor Mounting
Choose here the mounting orientation of the sensor in your model.

Direction of Main Rotor
Choose here whether the main rotor turns clockwise or anticlockwise.

Swash plate Type
Click on the type of swash plate used.

Collective Direction
VBar needs to know the direction of the swash movement for positive collective. Please check this on your heli and set it

Servo Directions
Now install the Mini VBar into your helicopter and connect the swash plate servos. It is very important that the servos are connected to the correct slots of your VBar (CH 1/2/3). VBar will not work if you have misconnected the servos.

Swash plate adjustment
In this menu, the swash plate is set to center position of its collective travel (zero pitch), and also leveled at 90° to the main shaft in both aileron and elevator axis using the controls per servo or per function. For this, it is necessary that the helicopter has been built with correct geometry (servos, swash plate, and linkages). A Pitch Gauge (swash plate leveling tool) is best to accomplish this task.

Adjust collective travel
Please set the desired collective travel here. The range for this is optimal between 80 and 100. You may reduce (but not increase) the pitch values later in your transmitter using the pitch curve function, e. g. if you measure different angles for maximum positive and maximum negativ collective. Check that your transmitter output doesn‘t exceed 115 % of travel in any case.

Adjust cyclic throw
Adjust cyclic throw here to the indicated value. The range between 80 and 110 is optimal.

The last step in the programming assistant is for the tail settings. Please first choose the tail servo used in your model, then connect the tail servo to the VBar by plugging the servo into the slot in the VBar labeled “Tail Servo”, to avoid servo damage. Finally you should check if stick travel and tail rotor travel correspond properly. If they do not, it is necessary to reverse the function in the software. The servo travels are set separately for each direction. For top performance, the values should be approximately equal for both directions. If that‘s not possible, move the servo arm by one notch around the center postion and try again. Programming is now finished. Go back to the main page by
clicking Finished.
