5 Liter gasoline and 100 ml oil = 50:1, or per liter gasoline 20 ml oil.
TAKE GREAT CARE WHEN HANDLING PETROL:
USE ONLY THE SPECIAL AIRTIGHT RESERVE CANISTERS
NO SMOKING!
Propellers
We have tested a range of propellers with the 45 and here are the results:
Menz “S” 2-blade props
Menz “S” 3-blade prop
18x12" 7,300 RPM
19x10"
6,000 RPM
19x10" 7,100 RPM
20x10" 6,800 RPM
21x8"
6,800 RPM
21x10" 5,950 RPM
Super Silence CF-3-blade
21x12" 5,500 RPM
19x11"
6,800 RPM
22x10" 5,400 RPM
20x12"
6,200 RPM
The above list of props were tested with the standard muffler and the 40 mm ram tube
order no. #0080 fitted to the carburettor. Without the ram tube the RPM is some 200
less; also the engine was not fully run-in, so the RPM figures can be in excess of the
above after say five hours running time.
You must balance every propeller. Some manufacturers claim they balance their props,
you should check this claim, as their definition for “balanced” may not coincide with
what yours should be.
WARNING:
Do not be tempted to use semi-flexible thermoplastic props; thermoplastic material
is not reliable enough for props of the required diameter, even if they are reinforced
with either glass or carbon fibres. With the large diameter, plus the ability of the 45
to run at high RPM, these plastic props are performing at and above the limit of their
durability. They will surely shed a blade sooner or later, due to material fatigue. This
fatigue effect can be increased by a model tipping onto its nose and bending the prop
severely, or by the plastic simply dehydrating.
