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
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 46–50 sized airplanes alongside or
underneath the recommended 6–8 oz 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 adequate 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.

Avionics Li-Fe Receiver
®
• 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.
• 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 your telemetry mod-
ule's rpm input port.
• Connect the spark plug connector to the
spark plug. This adapter has a push on and
rotate clockwise 1/8 turn locking
mechanism to insure a solid connection.
Make sure you charge your ignition battery
and are now ready to operate your electronic
ignition with the engine.
