Radio Control Aerobatics - 2008/05
THE CHINESE say that “A journey of a
thousand miles begins with a single step.”
In the case of the new FAI F3A World
Champion—Quique Somenzini—you could
say that it began with his first takeoff in
1977! Quique (pronounced “Key-Kay”)
flew a long journey to win the individual
World Championship back for the US in
2007.
Plane Talk: ASM P-61 Black Widow Twin ARF - 2007/08
IT IS EXCITING to put together an
airplane with more than one engine. It is
even more exciting when it is a semiscale
model of a World War II night-fighter.
Twin Tuning - 2007/08
Tuning a twin-engine
airplane: twice the
trouble or twice the fun?
Above: The engine is
inverted and the fuel-tank
position replicates the
tank location of the
intended twin.
Left: Side-mounting an
engine in a test rig
replicates the twin
installation for testing
and breaking in.

If programmed correctly, twin engines could make this airplane handle on the ground
and fly as if they were one power plant.
THERE IS NOTHING like the sound of
two engines beating out a synchronous sound
as you hold your model’s line in a
scintillating low pass down the center of the
runway. On the other hand, it does not sound
right or handle very well if one of a twin
aircraft’s engines is not set up to run as well
as the other.

Tune your engine exhaust like a pro
This month, I will explore engine exhaust tuning. One
of the most interesting aspects of being involved most
of my life with internal-combustion engines is sound.
There is something hardwired in us that causes us to react
differently to different sounds, and differently to the same
sound. A jet passing overhead is so commonplace today that
most never look up unless it is low or unusually loud.
