Flettner with Macrocells

App for VBar Control touch only on request available

If someone takes a look at all the public available flettner rotor helicopters - he will admit that they all have only 2 combined Aileron/Collective servos each swashplate. The reason for this might be in history as the available flightcontrols for such helicopters had this limitation. It is obviously that a "full control" over all 3 axis would be way better than they can do with only 2 of them.

Some days ago there was article series in a German magazine "RC-Heli-Action" about all the Flettner specific control which is highly recommened to read. The App was programmed on the conclusions out of this articles. As it is still in test status please check all adjustments carefully, especially stick and gyro direchtions.

We have implemented:

  • Basic model COG before main shaft, rigt rotor turns clockwise
  • Adjustable Aileron ratios (inner/outer rotor) to avoud collisions (blade-to-hub-clearance on small main shaft angles)
  • yaw control with diff-coll and diff-elev (fading with curves, adjustable)
  • Aileron must be reduced in autorotation (use Bank 4 with low agility)
  • Elevator surface control with collective (avoids ballooning effect)
  • Rudder surface with Yaw control (better control in flight)
  • Individual swashplates, rotateable for linear linkages

Our goal was to develop a app for the VBar Control touch which sets up all the basic parameters and all the macrocells behind. It gives a nice clean user interface to set up what might be needed in addition to the normal VBar NEO Pro parameters.

As we do not know your helicopter it is the pilots responsibility to adjust useful throws, control loop ratios etc. in the VBar. With the Macrocells we can give you best flexibility. Please check all directions etc. after a change of the setting before a flight. The pilot is responsible for safe operation.
