Additional installation notes
•
There must be a minimum 4" separation between anything attached to the receiver and
all things related to the ignition (i.e., the ignition itself, and its wires, battery, and switch)
•
Use a plastic spiral sheath to protect the ignition cables
•
Never remove the sparkplug cap by using a mechanical aid like pliers. Only remove the
cap by hand using a twist/pull movement.
•
The spark plug cap must be firmly seated to the sparkplug. If the spark plug cap is not firmly
seated there is a very good possibility that you will experience radio interference.
•
Use only ignition on/off switches recommended by 3W
•
6 volts is required for the ignition.
•
Do not skimp on your throttle servo. A high quality throttle servo is recommended for reliable
and accurate operation of the carburetor.
•
Never fill the fuel tank via the carburetor fuel line
•
Use the same I.D. for tank ventilation and the carburetor fuel line
•
Use small plastic cable ties on all fuel line to fitting connections.
•
We recommend cutting the fuel line in the fuel tank in half. And, then joining them back
together with a brass tube. The brass tube prevents a folding of the fuel line with could cut
the fuel supply for the engine (see tank photo).
•
The use of soldered on DUBRO barbs on the ends of the brass tubing is highly recommended.
Again, always secure the fuel line with small plastic cable ties.
