Connecting the Electronic Ignition

The Evolution Electronic Ignition Assembly is designed and engineered speciﬁcally for the

small block engine series. It is smaller and lighter so it ﬁts into tighter spaces of the airplanes

the engines are designed to power. The battery voltage required is between 4.8V (4-cell Ni-MH

pack) and 8.4V (2S Li-Po battery) and no voltage regulators are needed with any of these

batteries. We recommend a 2S Li-Fe battery (such as the Team Orion

Avionics Li-Fe Receiver

Pack 1300mAh 6.6V (ORI60503)) and we have done extensive testing with these packs. The

maximum amp draw at full throttle is 450mAh, and our more typical average has been between

250–300mAh.

The assembly consists of:

• Ignition module with battery connector, ignition sensor connector, tachometer readout

connector and spark plug connector

• Ignition sensor (already attached to your engine)

• Sensor magnet (already installed in the prop drive hub of your engine)

Mounting Your Electronic Ignition

• You can mount the unit in any orientation

and place that is convenient for your

installation. The module is sized to con-

veniently ﬁt into the tank compartment of

most glow powered airplanes alongside or

underneath the recommended fuel tanks.

You can also mount it to the ﬁrewall or

under the engine ﬁrewall extension if your

airplane is so equipped. Keep in mind that

it should be mounted away from the heat of

the mufﬂer.

• Secure the ignition module to your chosen

location with foam padding to provide

vibration isolation. We typically mount it

conveniently with tie wraps after wrapping

the ignition in lightweight 1/4-inch foam

rubber.

• You may need to route both the spark plug

connector wire and the ignition sensor wire

through the ﬁrewall, so be sure to plan

ahead and provide adequately sized holes

that will allow you to pull either the ignition

sensor connector or the spark plug cap

connector through the holes for later

ignition removal.

• Mount a good quality radio receiver type

switch between the ignition unit and the

battery. Mount this switch in a convenient

place on the outer fuselage close to the

front of the airplane to make it easy to turn

the ignition on and off. Being able to easily

shut off the ignition is an important safety

consideration.

• Connect the ignition sensor wire to the

ignition module. The sensor wire will only

ﬁt into one of the connectors so you cannot

connect it wrong.

• Connect the ON/OFF switch to the battery

connector lead of the ignition module. This

connector is the red connector.

• For added security and controllability, add

an additional radio-operated kill switch

(such as the Optical Ignition Kill Switch

EVOA100) between the ignition battery con-

nector lead and the ON/OFF switch.

• If desired, you can connect either the

separately available tachometer readout or

the included Evolution/Spektrum Telemetry

Adapter Cable (EVOA107) to the tachometer

readout connector. Plug the other end of

the adapter cable into the Spektrum

telemetry module’s rpm input port.

• Connect the spark plug connector to the

spark plug. This spark plug connector

utilizes a locking snap ring to ensure a

solid connection. Push it straight onto the

spark plug to secure.

Make sure you charge your ignition battery.

You are now ready to operate your electronic

ignition with the engine.
