surfaces move to their absolute maximum
travel deflections, which are typically
45 degrees with 65% exponential. The
best way of finding the proper amount of
exponential is to adjust the amounts until
the aircraft performs with a consistent feel
on all control surfaces without decreasing
the amount of precision.
Scale Flight ModeS
When flying a giant-scale fighter like
a 102-inch Fw 190, I prefer to use two
different flight modes coupled with a
three-position flap switch and a two-position retractable landing-gear switch.
Try to keep your radio setting the same
for multiple airplanes. With a two-position
switch for retractable landing gear, for
example, always make sure position 0
has the same result for each airplane.
Consistency between setups greatly
simplifies your workload when flying
The first mode is only intended for
taxiing. On this rate, 20 degrees of elevator,
rudder, and aileron deflection are coupled
with 20% exponential, which provides just
enough elevator deflection to keep the
tail on the ground while travelling over
rough terrain. On the second rate, about
15 degrees of elevator travel, 25 degrees of
aileron, and 20 degrees of rudder travel are
set with 30% exponential. This allows scale
roll rates and pitch changes during flight.
Some warbirds have a tendency to nose-over on landing, so I land using my general
flight mode. As soon as the aircraft touches
down and begins to bleed off airspeed, I
switch to my “taxi” mode and apply full
up-elevator to keep the tail down.
My switch assignments are based on
my personal experience with scale models.
Some, however, might prefer to assign
certain flap deflections to their flight-mode
switch, as well. This combines the use
of the flight mode, flap switch, and gear
switch all on a single switch to decrease
the pilot’s workload for complex scale
It helps greatly to simplify all flight-specific functions so that you can focus
on performing each flight to the best of
your ability, and flight modes using one
switch to adjust rate settings for various
flight conditions is the best way to do this.
Like everything else, difficult tasks are
often easier to overcome with the help of a
mentor. Don’t be afraid to seek the advice
of experienced giant-scale enthusiasts to
help build confidence.
