allow it to come into contact with the eyes or
mouth. Always store it in a clearly marked
container and out of the reach of children.
Model engine fuel is also highly flammable.
Keep it away from open flame, excessive
heat, sources of sparks, or anything else
which might ignite it. Do not smoke, or allow
anyone else to smoke, near to it.

To prevent the pickup from adhering to
the tank wall
restricting fuel flow, slots may be filed
I the end of the weight. Alternatively,

Fuel Filter
It is recommended to fit a good
in-line filter between the fuel tank
and carburetor to prevent entry of
foreign matter into the carburetor.
Fuel Tank

A fuel tank of approximately
300cc capacity is suggested.
This allows around 10 minutes
flying time, dependent upon the
type of fuel used, the size of propeller and on
the proportion of full-throttle to part-throttle
operation throughout the flight.
