• Because the receiver and servos will receive power from the 3-in-1 control unit, it will now be necessary to
disable the BEC power of the brushless ESC before connecting it to the receiver. To do this, it will be necessary
to remove the red (positive) lead and connector from the plastic housing that goes to the receiver, then to
insulate it properly to prevent shorting. Use a small screwdriver or knife blade (and extreme care to prevent
injury) to lift the plastic tab that secures the connector in the plastic housing, then slide it out the back end of
the housing. Use tape or shrink tubing to insulate and secure the exposed connector.
Note: It is extremely important to disable the BEC of the brushless ESC in order to prevent damage to
the other electronics. Remember, BEC power is already supplied to the receiver and servos through
the 3-in-1 control unit throttle and rudder leads.
• Now that BEC power of the brushless ESC has been disabled, connect its receiver lead to one of the female
connectors of the 3” Y-Harness (EFLRYH3). Next, connect the Throttle (Channel 3) receiver lead of the 3-in-1
control unit to the remaining female connector of the 3” Y-harness. Then, connect the male connector of this
Y-harness to Channel 3 (Throttle) of the receiver.
