In these settings for example additional features such as CareFree or Emergency-gas can be set.

Choosing the functions

• Min. Gas

  • Minimal gas value, which goes to the motor

• Max. Gas

  • Maximal gas value which goes to the motor

• Compass effect 

  • Is a compass connected the influence of the yaw can be set up here. In that case a small number has a small, one large number has a big influence.

• Carefree control 

  • Is the value "0" the function CareFree is off. To toggle the function at the transmitter you can set up a potentiometer.

• Under voltage 

  • The threshold is set in 0.1 V steps to report the battery-low voltage.
    The default setting is 33 (3.3 V). This is the voltage of each cell in a lipo that should not be exceeded. (Infos about the Lipo you can read here: Lipo)
    When you turn on the Kopter it will detect automatically if, for example, a 3S or 4S Lipo is connected.
    Info: After switching on (1 x a slightly longer beep) is heard, the detection of cells: 3S = beep 3x, 4x beep = 4S; ...

Loss of receiving 

• Emergency-Gas Time [0.1s]
  

  • Here the time is entered in tenths of seconds for which the gas is actively seeking emergency reception failure. As a value, a number 1-247 can be entered.
    So it is a maximum time of emergency-gas (247 x 0.1s) 24.7 seconds possible.
    

• Emergency-Gas
  Here the gas value is entered for the motors. This value should be determined first individually (depending on the weight of the Copts).
  The value should not be set too low or too high. The Kopter could otherwise fall upon receiving either too fast or fail to rise into the sky and crash at the end of time.
  This causes of course the risk that the Mikrokopter drops at an undesirable location (obstructions, trees).
  
  Important: If you activate Use vario control for failsave altitude, the Emergency-Gas is entered as a percentage (%). Here on the Not gas will be calculated automatically.
  
  

  • Failsave CH time
    

    In case of RC transmission-lost the MK will fly now automatically for 60 sec. to the Home-Position.
    (Commercial users can determine up to 247 Seconds.)
    See also: FailSafe

  • Failsafe channel
    

    • If a reiceiver is used which is not showing a receiving failure a loss of the received signal will be not detected and the Kopter would continue to fly with the last received settings.
      Here you can enter a free channel. This channel must be set over the "Failsafe" of the receiver so that the channel is switched off during a loss of a received signal.
      Is that channel available on a button at your transmitter you can use actually that button as a test-button for the function "Failsafe".

  • Error-Beep (No beep without active transmitter)
    

    • If you power on your Kopter and the transmitter is not swiched on, the Kopter give you a beep signal. This beep signal will stop if you swich on the transmitter.
      After activating this function, the kopter will not beep after you power on the Kopter and forgot the transmitter.

  • Use vario control for failsave altitude
    

    • If this function will be activated the percentage sign (%) will appear before the "EMERGENCY-Throttle/Gas". 
      With that function it is possible to calculate the value of the Emergency-throttle/gas automatically.
      In example, if you enter here the number 80 the emergency-throttle/gas will be set on 80% of the normally used hovering-throttle/gas.
      The value should be set in that way that the Kopter looses altitude quickly.

  • Compass error
    

    • If you click here "ignore magnet error at startup" magnet failure messages will be ignored which are avoiding a start of the Kopter.
      The Kopter can be started and flown. Present magnet failures can interfere the flight and could cause a malfunction of the Kopter.

  • SD card missing
    

    • If you click here "not start without SD card" the Kopter will start only with the insert SD-Card. 
      That can be necessary for the commercial use of the Kopter if certain legal requirements are requested.
      (i.e. range limit, Emergency program within an unforeseen exit of a prescribed radius, etc.)
      (See: FailSafe)

  • GPS fix missing
    

    • If you click here "not start without GPS fix" the Kopter will only start with a made Sat-Fix. 
      Without a Sat-Fix the GPS-Functions like PositionHold, ComingHome or FailSafe are not possible.
      To ensure that the GPS functions can be used you can activate this function.

  
  
  

  Important

  That functions and the settings of the FailSafe are described here: FailSafe

  
  
  
  
  

  • Info: 
    This Emergency-Gas function is used at your own risk. In the event of a loss of reception the Kopter may come down with a sink rate defined here.
    The Kopter comes down there where the loss was of the reception. Damage to the MikroKopter can not be ruled out!
    
    

     To display this feature, the receiver must receive the loss. This can easily be checked: 
    

    • Receiver is connected to FlightCtrl. Transmitter and FlightCtrl are switched on (powered). 
      Now, the transmitter is turned off the red LED lights on the Flight-Ctrl. and the buzzer gives a warning signal. 
      
      

    If there is a loss of reception (e.g. from out of range or transmitter off), the gas emergency regulation becomes effective. 
    The engines will bee operated for a preset time with a preset value of emergency gas and shuts off when the time expires
    
    

    Note : 
    The entire emergency gas control is only active when a gas-value of >40 for at least 4 seconds was exceeded (i.e., the MikroKopter flies probably)!
    
    

    Obtaining Emergency-gas values: 
    

    • On an open field with plenty of space, the required emergency gas value and the function can be flown easily tested.
      To read the values​​, perhaps, a second person could be there and help.
       You can store different emergency gas levels in the various settings. !!!
       If, for example, a camera is carried later on the MikroKopter the UAV is heavier and therefore it must be another/different Emergency-gas time adjusted. !!! 
      
      
      

      The easiest way to determine the needed gas value is in the KopterTool. This should include a data link between the MikroKopter and the PC ( or laptop) to see the data in KopterTool ..
      This can be done over a Bluetoothmodul or a Wi232 Modul .
      

    If the connection is available you can change in the Kopter-Tool into the following display (with the red arrows): 
    

    •  
      
      

      Now the Kopter can be started and you can hover in a height of approx. 15 - 20mtr (or higher). All additional features such as height, PH, etc. are off.
      The value now displayed next to Gs: is the gas float value. 
      Now, the gas can be reduced slowly so that the MikroKopter falls. If you have a proper rate of descent and if this value is reached, the value can be read next to Gs:.
      This value can be entered now as Emergency-gas .
      
      

      If the value is entered and stored in the Flight-Ctrl. the MikroKopter can hover in the air and you can turn off the radio once. 
      The copter should come down now with the emergency gas setting and shut down after the set time, the engines.
