CareFree



Care-Free-Control

In this mode, the control direction of Nick and Roll is not made by "Front" definition, but by the direction in which is positioned the MK front at the Start engines moment. So you can yaw the MK without it having any co-rotation effect on Nick and Roll.

Tips:

  • You must first get used to the fact the is no more front arm.
  • /!\ The pilot should not ever change orientation, otherwise will be confused. Exception: in Teachable CareFree it is possible (see below)

  • For safety you should practice in an open area and use GPS-CH to get back.
  • The compass must be properly calibrated to work well and safely

  • WARNING: Looping will not work with Carefree
  • {i} This feature requires a Navi Ctrl with a Compass

CareFree is implemented since version Version 0.80

Teachable CareFree (CareFree 2.0)

{i} "Techable" means, that the control direction can be changed during flight

So, the control direction will be "teached" each time, the assigned CareFree-Switch is switched on.

A distinction is made:

  1. Within 20m of the starting point, the front-direction of the MKs will become the control-direction
  2. Outside of the 20m, the bearing between home and MK-Position will become the control direction

So the pilot can now rotate on the spot, because he can teach-in a new CafreFree-direction by using the switch. Outside the 20m he does not even have to see where the front-direction was at the time.

{i} Tip: If the pilot has the MK well in sight, he should turn the MK so, that the nose points directly away from him. Then it does not matter if the MK is inside or outside the 20m - the control direction would be the same in in both cases anyway.

{i} the operation of CareFree 2.0 is more intuitive than you think

Example 1:

  • In case that the MK is too far away and the Pilot does not know its actual direction, he would have problems controlling the MK manually
  • Now the CareFree-Switch could be switched on and the Pilot would simply fly as if the nose would point away from him

Example 2:

  • The pilot stands at a building that he wants to photograph
  • He would use CareFree and turn the MK 180° in his direction

  • If he wants to take photos from the other side of that building, he could re-activate CareFree on the other side of that building and turn again 180° into his direction

Note: This function is implemented since Version 0.86

  1. Direction of the MK before activating the CareFree switch

  2. CareFree is switched on -> the actual direction will become the control-direction

  3. Even if the MK is turned, the control direction will remain equal

  1. Direction of the MK before activating the CareFree switch

  2. CareFree is switched on -> the actual bearing between MK and pilot will become the control-direction - no matter of the actual MK-Direction

  3. Even if the MK is moved and turned, the control direction will remain equal

The pilot wants to teach-in a new CareFree direction, even If doen't know the actual direction of the MK

  1. CareFree was already on, but the control direction is inconvenient

  2. If the Pilot switches CareFree off, the actual direction will become the control direction

  3. CareFree is switched on -> the actual bearing between MK and pilot will become the control-direction - no matter of the actual MK-Direction
