Ignition (continued)
•
Always perform a radio range check before flying. Range should be at least 200 Ft. with the plane on the ground and
the motor running. If there are “glitches”, DON’T FLY! Check for damage, loose connections, faulty radio/servo
components, etc.
•
When removing the spark plug caps, PULL STRAIGHT out on the caps.
Do not pull on the ignition wires!
If caps
seem loose and are not making a solid metal to metal contact with the spark plug base, use a small hose clamp
around the base of the cap to keep them firmly attached to the base of the plug. To prevent radio interference, the
spark plug caps must have the split retainer ring around the base to insure a tight fit. – DON’T FLY WITHOUT THEM!
•
Timing is set at the factory and should not need adjustment. Contact Desert Aircraft if you have any questions
regarding timing.
•
Only use NGK CM-6 spark plugs. Other plugs may not fit the plug caps firmly.
•
Plug gap is .018” to .020" (.38 to .50 mm)
•
Never operate the ignition without a spark plug in the plug caps! This can permanently damage the ignition coil.
