✽
CONNECTING WITH THE EC-1
(1) Injection Time Input Terminal (CH3 THRO)
Connect the y harness provided with the CH3 THRO input terminal to throttle channel (3) of the
receiver (throttle: CH3), connect the wiring connector from the throttle servo to one of the double-
opening connectors on the opposite side, and connect the other double-opening connector to
CH3:THRO of EC-1.
(Use the separately sold extension cord if the wiring cords are too short.)
Connect the receiver and servo-related components (rudder section) in the same manner as in the
past.
(5) Rotation sensor input terminal (r.p.m.)
(4) Temperature sensor input terminal (Temp)
(3) Injector output terminal (INJECTOR)
(2) Injection trim input terminal
(AUX TRIM)
(1) Injection time input terminal
(CH3:THRO)
Two extension cords (sold separately) of
a length corresponding to the airframe
are required for connecting (1) and (2).

LCD contrast:
Turning to the right = darker,
turning to the left = lighter
(2) Injection Trim Input Terminal (AUX TRIM)
Connect a spare channel for dial use of the receiver (e.g. channel 7) to the AUX:TRIM terminal.
(Use the separately sold extension cord if the wiring cords are too short.)
(3) Injector Output Terminal
Connect the injector connector to the injector output terminal. Protect the lead wire with a heat-
resistant tube,etc. if it makes contact with the engine mount.
(4) Temperature Sensor Input Terminal
Connect the temperature sensor connector to the temperature sensor input terminal.
(5) Rotation Sensor Input Terminal
Connect the rotation sensor connector to the rpm input terminal.
Note:
Soft mounts may become soft due to excessively high temperatures leading to increased
vibration amplitude of the engine. Make connections so that the lead wire does not make
contact with the engine mount, manifold or airframe under any conditions.
