The following steps should be completed before
the controller is used for the rst time:
Caution!
Observe the Chapter entitled “Safety notes”.
· Check that the basic settings match the battery,
motor and model type.
· Ensure that your model is securely restrained.
· In the interests of safety remove the propeller
(aircraft or boat) or the rotor blades.
· Locate the receiver leads attached to the speed
controller, and connect them to the receiver as
already described.
· Switch your transmitter on.
· Move the throttle stick and trim to the Idle end-point.
· Connect the ight / drive battery to the speed cont-
roller, maintaining correct polarity.
· After about two seconds you will hear a conrmation
beep which indicates that it has detected the idle
position of the throttle channel. (If you do not hear
this beep, please check the travel and trim setting
for the throttle channel).
· Slowly move the throttle stick in the direction of
full-throttle.
· Check the direction of rotation of the motor. If it spins
in the wrong direction, you can either recongure the
direction or simply swap over any two of the three
wires running to the motor.
· Carry out the following procedure as a practical test
of the BEC system under load:
Monitor the current drain in the telemetry display on
your transmitter. While you do this, place a load on
the BEC system by moving all the servos briskly for
a period of about ve minutes. If the display shows
a peak current above three Ampere, if a warning ap-
pears on the receiver operating voltage display, or if
the ashing rhythm of the receiver LED changes, it is
essential to use the smoothing capacitor included in
the set. Repeat the test, then disconnect the battery.
