On  Ailerons  and  Elevators,  UP  and  DOWN  travel  should  be  entered,  always  in  positive 
numbers, if travel is symmetrical, enter same number in both boxes.  Rudder and Flaps need 
only one value to be entered. 
 

Once  values  are  entered  it  is  possible  to  change  between  Degrees 
and  mm,  the  system  will  automatically  display  the  calculated 
Degrees value for data entered in mm and vice versa.  
 
Please check the “Setup the model” section for a description of how 
the  data  is  entered.  Don’t  forget  to  click  on  “Save”  before  exiting 
this window. 
 

 
 

Measuring 

 

Click on “Angle” button on the main screen to go to Measures 
Screen.  Besides  the  graphics  described  above,  there  are  two 
buttons: 
The  left  side  one  (“Ailerons”  on 

picture  16

)  allows  to  select 

the  surface  to  be  measured.  The  BLUE  lines  on  the  graphic 

(

Picture  15

)  will  be  drawn  accordingly  to 

the data entered for this particular surface 

and  the  color  of  the  position  line  will 
change  accordingly its  position, turning to 

GREEN in color when in correct position at full deflection. 
 

The Side Buttons allow selecting the reference for the measurements. 
Five options are offered (

Picture 17

): 

 

1)

 

Ground Absolute

: The 3 sensors work independently, and 

the zero is absolute, factory calibrated, like a bubble level, 
zero  degrees  will  be  displayed  when  the  sensor  is 
absolutely parallel to ground. 

 

2)

 

Ground  Relative

:  The  3  sensors  work  independently,  but 

the zero can be reset. Click on the “Set Zero” button to set 
all  3  sensors  to  read  zero,  whatever  position  they  are  in. 

Use this setting when adjusting the surfaces and need 3 measurements at a time, like 
adjusting Flaps/Elevator mix. 

 

3)

 

Reference  Sensor  Absolute

:  The  readings  of  sensors  left  and  right  show  its  angular 

difference  against  the  reference  sensor  (the  one  connected  to  “NOSE”  input).  Useful 
when you need to compare the incidence of a surface compared to a reference line on the 
fuselage. 

 

4)

 

Reference Sensor Relative Horizontal

: Same as above, but with the possibility to zero the 

readings on a given position.
