Connection diagram for the Airspeed Sensor:
Connect the air lines from the pitot tube to the airspeed sensor, using the 1/16
th
inch ID
vinyl tubing.
1 = Dynamic pressure input
2 = Static pressure input
Note:
Tubing length and/or cross sectional area has no influence on measurement
precision
Connect the
Airspeed Sensor
cable to the appropriate socket, where indicated on the
ECU (see: engine diagram in the Operation Manual). The orange wire is aligned to the
pulse symbol. Once the
Airspeed Sensor
is connected, the ECU controls additional
functions:
•
under
the
Run
menu
,
measurement of current air speed (“
Airspeed
”) and
desired flight speed (“
SetSpeed
”), can be displayed
•
under
the
Min/Max
menu, the measured maximum speed (“
MaxAirSpd
”) and the
average flight speed (“
AvgAirSpd
”), can be displayed
•
under
the
Limits
menu, speed limits and the parameters of speed regulation can
be predetermined

Explanation
SpdCtrl SW0 Act
With the
Airspeed
Sensor
connected to the ECU – by moving the
AUX
switch to the
Off
(
SW0
) position, while maintaining a model air
speed
>
40km/h, the following options are available:
Hold-Speed
= momentarily sustains the current flight speed
DISABLED/NONE
= no function,
thrust control
remains active
Turbine OFF
= turbine will immediately shut off
LrnSpeed Lo/Hi
= learn minimum or maximum flight speeds
Lrn Speed Lo
= learn minimum flight speed
Lrn Speed Hi
= learn maximum flight speed
