I finish loading the basic T500 file on my V-bar. everything look nomal except for

When I test the heli by picking it up by hand and move it forward, the Swash move foward as well. should the swash move backward? If yes, How would I change it?

I have very short rudder travel, How would I increase rudder travel by using V bar software?

Sensor reverse under the cyclic menu, if the swash is traveling the right direction for inputs.

Limits are set in the tail menu it's the DirA and DirB settings.

Read the Wiki, I just updated it a little so it's simpler to read in English now =)

Thanks

I got sensors reverse. It works fine now.

I increase DIRA and DIR B to max 127 but It only travel full one side the othe side only travel half.
I read WIKI. thanks again

Your mechanical setup must be out for your tail servo. Adjust the ball out on the horn and center the horn properly, then adjust in the v-bar.

When i turn on the helicopter, after innitialization, should the pitch slider return to its center position?

If yes, mine is in center position but go full travel only 1 direction and 1/2 travel in the other direction

If no,
How do i make pitch slider return to center position before mechanical adjusting ?

Thankyou

Here's what the wiki says:

Step 18: Tail Servo

Select your servo type in the "Tail" menu.

Step 19: Direction of Rotation

Set up the direction of rotation of the tail servo in the "Tail" menu so that the tail blades move correctly. The setup logic is the same as with any other standard gyro.

Step 20: Neutral Position

Via "neutral" in the "Tail" menu you set up neutral postion of the tail servo. Neutral in this case means the helicopter does not torque. This is best done by enabling the test mode in the "Flight Parameters" menu and setting the rudder to 0.

Step 21: Rudder Sensor

Set up the direction of operation of the rudder sensor in the "Tail" menu as you used to do with any other standard gyro.

Step 22: Tail Torque Compensation

Set maximum pitch at the radio. The tail torque compensation now adds some input to the tail pitch. That input needs to be in the correct direction, the tail blades must get more pitch. If not do the following:

1. Reverse the RC input in the "Tail" menu
2. Reverse the rudder sensor in the "Tail" menu
3. Reverse the tail servo in the "Tail" menu

Recheck all directions of operation.

Step 23: Travel limit

Set up the travel limit of the rudder.

Step 24: Zero Collective

The zero collective correction indicates the point of minimum torque in the system. This will be 0° collective when used symmetrical blades and about -1,5° collective when used airfoil S blades.

For adjustment, set the heli to 0° (-1,5°) collective by stick input. Click onto the button, ready.

3D pilots simply set "hover collective correction" to 0.

Step 25: Rate correction

Check in the "Tail" menu the rate correction. The current version (with USB connector) needs to be set to 85 as it is made for gasser helis. To change to value select "IC Sensor". Older versions (with serial connector) can be set to 64 for electric helis.

Oh Man! First test flight was amazing!I can feel the stability. However, It is so freaking fast for me
I use the basic T500 file that comes with Vbar software.

Now I have to go through Wiki to learn how to slow down Cyclic, elevator and rudder.

Any help will be thankful here.

Thanks

Which version of the software comes with a t500 setup? I have 3.6.16 and it is not there.

It's in preset setup. You may have to hit "Start setup" then it's in step one "Load Preset"

I got the same 3.6.16

Did you mean T500 files?

Yes, load Preset and select t500 file.
