Ignition System Installation
The ignition module should be mounted to your model’s firewall, as far away from your airborne radio
equipment as possible, and protected from excessive heat. We recommend securing it into place
using double-sided tape or silicone glue. The ignition system includes a kill switch which should be
mounted in a convenient location on the outside of the model. For safety, a second servo -operated kill
switch (not included) can be installed so that you can remotely shut off the ignition.
We recommend the “SmartFly” Optical cable engine cut-out switch as the best method for
this.
IMPORTANT
The timing ring and the coupled spark advance system comes preset from the factory to provide a
good combination of high power output and reliable idle, Do not readjust the timing linkages.
Throttle Pushrod Installation
To reduce the chance of RF interference, we don’t recommend using a metal pushrod wire. We suggest using a
nylon tube-in-sleeve style pushrod. The machined aluminum throttle bellcrank on the engine includes three
predrilled pushrod connection locations that are threaded for 4 -40 size ball links. For the best mechanical
advantage and smoothest throttle transition, we recommend installing your pushrod into the outermost hole in
the bellcrank.
With the spark plug installed in your engine, push the rubber boot over
the end of the spark plug until it ignition system, secure the grounding
wire to the top of the cylinder head using the socket-cap screw, as
shown. Now plug together the ignition lead from the engine and the
ignition lead from the ignition module. To power the ignition system you
need to use a separate battery pack that is 6.0V (5 cells) and a capacity
of 1100Mah to 3000Mah. NiCD or NiMH cells can be used. The battery
should be wired to the kill switch (making sure that the polarity is correct)
and mounted inside your model, at least 12 inches away from the ignition
module. For convenience, a charge jack can be wired along with the kill
switch so that you can charge the battery without having to remove it from
the model.
The “SmartFly”Ignition Cutoff provides safety and convenience for your
gas powered plane. The unit has two modules that are connected by a
fiber-optic cable. There is no electrical connection between your ignition
and your radio system. The unit recognizes dual-receiver setups and
allows your engine to keep running if you lose power to the receiver the
Cutoff is controlled by but your second receiver still has power. You are
not forced to land dead-stick as with other units on the market. The LED
on the ignition side is removable and extendable with standard
extensions. The LED is not required for the unit to operate properly.
Muffler Installation
The muffler is mounted to the engine using the two steel socket-
cap screws, two split washers and the gasket provided. To
prevent the muffler screws from loosening during flight, apply blue
thread lock to the screws before installing them. Also make sure
to tighten the screws firmly.
IMPORTANT
The muffler can be installed either upright or upside
down to suit your particular installation.
