4. Connect the ignition module battery to the kill switch. Any 
4.8- 8.4 V, 1000 mAh and above capacity battery will work well for 
this. Use heat shrink tubing to secure this connection. Optional: 
Install the TX activated gas engine kill switch (DLEG9205) between 
the manual on/off switch and the ignition as shown above. This is 
especially important during the starting sequence as it requires 
the manual on/off switch to be in the ON position before ignition 
can occur. The kill switch LED should be installed on the exterior of 
the aircraft so that it’s visible from the front of the aircraft. This is to 
ensure that the person starting the engine is aware that the ignition 
is armed. If properly installed as shown above, an illuminated red 
LED indicates that that the ignition is armed.
5. Install the ignition on/off switch on the aircraft so that it is easily
accessible through the cowling or the fuselage.
6. Install the ignition module 
and battery securely in the 
airplane forward area. It is 
recommended that a thin 
piece of foam rubber is 
placed between the module 
and the mounting surface 
and that Velcro
®
strap is used
to hold the module in place.
7. Install the remaining silicone wire cover over the ignition wire.
8. Install the spark plug into the engine head (7– 8 lbs torque). Do
not overtighten.
