Before connecting the throttle linkage, make sure that the
throttle valve lever does not interfere with the bulkhead or
mount of the model when it is fully closed and opened.
Connect the throttle linkage so that clearance gap between
the idle stop and idle speed stop lever distance is
1~1.5mm (refer to the sketch shown below) when the
throttle stick on the transmitter is fully pulled down and the
throttle valve is fully closed as well as the trim lever on the
transmitter.
Connect linkage so that this
gap distance is 1~1.5mm.
(This is the idling position.)
Idle Stop
Idle Stop Lever
Connect the linkage so that the throttle valve is fully
opened when the throttle stick on the transmitter is fully
advanced. (Adjust the movement so that the pushrod does
not bind when the throttle valve is fully closed and fully
opened.)
Connect the linkage so that the servo arm and pushrod,
and throttle valve lever make a right angle when the
throttle stick on the transmitter is placed at mid position to
avoid differential action.
When changing the throttle valve lever and choke valve
lever direction, loosen and tighten each retaining screw
placing each lever at mid position. (If the throttle valve
lever retaining screw is loosened or tightened with the
throttle valve fully opened or closed, excessive force will
be applied, which will results in breaking the lever.)
There is no need to connect to the air vent fitting in normal
use. However, if the engine does not run steadily due to
pressure change caused by airflow in the cowl, connect
tubing to the inside of the fuselage.

Consumption current is 600mA/6,000rpm.
User a power source of more than 1000mA/h capacity.
For safety, with this ignition module the engine runs
intermittently over 5,000rpm when the power source
voltage drops below 3.8V.
With this intermittent running rpm do not increase the rpm
above mid speed, and land the model immediately.
The ignition module is set not to operate below 100rpm for
safety.
The voltage of power source is 4.8~7.4V (rated).
(Ni-Cd, Ni-H 4~6 cells, Li-Po, Li-Fe 2 cells)
When checking the spark plug with the power
source on, do not hold the plug, plug cap, high
tension cord nor grounding wire, or you will get a
shock.
Be sure to equip an externally-operable switch for
the ignition system battery to stop the engine if
started unexpectedly without switching on the
radio system, or there is a possibility of injury.
IGNITION MODULE
Major specifications
Installation
Install the ignition module taking sufficient anti-vibration
measures.
Install the ignition module at least 100mm away from the
engine and in a place where there is airflow so that engine
exhaust heat and radiation heat do not affect it's operation.
Do not share the power source with receiver and use a
separate power source.
Equip an ON/OFF switch between the ignition module and
its power source and install it in a place where can be
operated from outside the model.
Install the ignition module and its power source as far as
possible away from the servos and receiver power source.
Connect the ignition module grounding wire to the engine.
Make sure the jackets of high tension cord and grounding
wire do not touch the engine and cowl to avoid accidental
short circuit.
Install he plug cap on the plug securely.
