O.S. ENGINES never runs out of new
ideas, such as the double-ball-bearing O.S.
.55 AX ABL. (The last three letters stand
for Advanced Bimetallic Liner, which is
an improvement on the “ABC” system.
The “ABL” design uses a double layer of
chrome and nickel electroplating in its
brass liner bore. This provides stronger
bonding between the plating and the sleeve
and greater durability in service.)

Model engine fuels and lubricants
A SUBJECT THAT comes up regularly in
mail from readers is about fuels for various
types of model engines. I wrote about model
diesel fuel in my previous column; this time
my topic is fuels for glow and “gas”
engines.

MAGNUM’S BIG XL 180 RFS four-stroker
is a ringed-piston design and a mighty potent
engine. Weighing 39 ounces, it’s extremely
well made and spins a 16 x 8 propeller from
1,800 to 10,000 rpm after being fully broken
in.

UP TO NOW the material in these columns has been mainly aimed
at modelers who have had some experience with model engines.
But Model Aviation Aeromodeling Editor Bob Hunt recently
reminded me that many of today’s AMA members start in Radio
Control (RC) without any previous acclimatization period in Free
Flight or Control Line flying.
