Basic Setup

First install the required Tandem/Flettner App to the VBar Control touch through the WiFi / App Store. The used NEO VBar must have pro or pro rescue loaded. Connect the 2 NEO's and set them up as master/slave through the interbus before starting.

 

To configure a new Tandem just select. After confirming we will erase all NEO values and upload the whole setup including macrocells. The Swashplates can be set as H-3 or H-4 afterwards seperately.

 

 

Using a different swashplate, just select for each rotor the right one. This will load/reset the required macrocells. You can also use different swashplates in front and back (but same linkage count) rotor. In the swashplate expert (long press) the angles and distances can be set up as liked, rotation is also done there to get straight linkages. the collective direction can be set up individually too.

Tip: Rotate the swash at the end when all values are set up, makes it easier to check the directions during setup ;-)

 

 

 

In directions dialog set them up as needed and check all movements (Aileron, Elevator, Collective, Yaw). If a servo will be plugged into a wrong socket you won't get any useful movements ;-)

 

As usually the servos are blocked at the trim panel in center position. Mount/move/align the servo horns to 90° here and trim the rest with either the servo trim (long press) or the "complete Swash" (normal press) trim. Lengthen the rods from servo to swash to get the swash at half of its range. Now you can set up the rods to the head for 0° as for trainers (if you have enough throw for the other controls). Otherwise set up half of the collective range now (e.g. from -4 up to +10° we have 14/2=7°, starting from -4 means +3° to be set). Afterwards move stick to zero position and set this in one of the swash experts. Check Yaw control fading afterwards - it must have been fading from diff coll to diff elev fully when one of the swash touches 0 deg. collectice!.

 

 

Basic mixers and control curves (yaw fading) are set here:

 

Now change to the in the "Edit Model Setup". Please set up only Model Name, VBar NEO orientation, collective, cyclic values and ESC / Gear setup. If collective/Cyclic won't be in a range of 80...100 improve your geometry (swashplate, servo horns). All other values are set up already!

Perform a throw check while being in this panel or in the Tandem/Flettner Special panel. Even at approx. full collective should be enough headroom for cyclic and yaw commands w/o mechanical binding or straightened linkages/horns.
