Note: There is a known bug on version 1.0 when measuring the CG on Bicycle (Tail Dragging)
planes. Tricycle works correctly. Contact Xicoy for last version of upgrade files.
Measuring angles
In order to measure angles, your unit should be updated to software version 1.3 or higher, and
the angle sensors purchased separately.
The unit can measure up to 3 different angles at time. The sensors measure inclination relative
to the ground, with a precision of 0,1º. Therefore, surface to be measured should be placed
parallel to the floor. Ailerons, Flaps and Elevators can be measured normally, but to measure
the Rudder, it is necessary to rotate the fuselage 90º.
Measurement is displayed in graphical and numeric form. Usual application is to place the
sensors connected to “Left” and “Right” inputs in to surfaces to be measured (Ailerons,
Elevators, Flaps). The 3rd sensor can be used as a 3rd measurement or as a zero reference for
the other two sensors.
The graphic includes the current position of the surface and the
maximum deflection positions, marked in BLUE lines. The current
position line is YELLOW in color when the position of the surface
is between minimum and maximum (
Picture 12
). The color will
change to GREEN when the deflection is exactly as desired (+/-
0,5º). If the deflection is excessive, then the line color changes to
RED.
Entering the data of the surfaces:
The unit accepts the data in either Distance or in Degrees.
Usually the manufacturer’s instructions of aero models specify
mm of travel at the Trailing Edge of the surface.
Once you know the measurements required, for your plane, click
on “Select Model” on main screen (
Picture 13
). If you already
have defined this model on the system, just select it, if a new
model; enter the name and CG data as described in the CG
Measures Section.
Once the model is selected, click on the “Angles” button.
If Deflection requirements are defined in Degrees of Deflection, click on “Set Degrees” button.
The units will change to Degrees.
When Deflection requirements are in Degrees, it is not mandatory to enter the width of the
surfaces, but if you enter the data in mm, then you should measure the width of the surface,
from hinge line to point of measure. The system will use this data to calculate the angle.
