Center-of-gravity location, control-surface throws, rate setup, and more good info is typically
found in the manual, so I generally rely on it. ;e recommended settings are great for starting
points, but if you’ve ever wondered why some pilots’ planes seem to fly so much better than
others—even when employing the same airframe—it could be the mixture of things. ;e
Multiplex 330SC instructions provide some mix values, and when used, they provide pilots with
that extra assistance.
Mix #1 Rudder/Elevator
So you roll to knife-edge and are thumbing away wondering, “Why am I fighting to keep it here?”
To answer the question, first identify what is happening: Is the plane pulling toward the landing
gear or canopy? If there is a tendency to pull toward one side or the other, the method of mixing
some opposite elevator input to counteract this flight condition will lighten your thumb load. Pulls
to canopy?: Create a mix so that, when you input rudder, the elevator will automatically move
down, compensating for you. Pulls to gear?: Create the mix to add up-elevator. ;e percentage
you add is key and can best be found through experimentation. Start with a low percentage—
maybe 3 to 5%—and adjust as needed.
Mix #2 Rudder/Aileron
Your test flights revealed some adverse roll during the knife-edge condition; by mixing some
opposite aileron input when rudder is applied, pilots can decrease even more thumb load. Again,
test and retest with di;erent values (percentages) and find what works best for you. When you
get it nailed down, your knife-edge flight should almost be doable one-handed.
The Elapor foam airframe is stout, forgiving, and easy to repair if necessary.
With some low-cost 3-cell batteries, you’ll be flying all day and practicing your
hardcore “huck” moves down low without worry. The provided power system
is perfect, delivering smooth and “excessive” thrust (if there is such a thing!),
making any poststall maneuver or tumble-type move doable. The bright color
scheme is art in the air and makes orientation easy. You’ll want this one! ;
small elevator inputs to control the speed and
angle of attack. Harrier landings are easy to
do, but greasy three-pointers look cool too.
A short roll follows touchdown and after the
speed bleeds o;, planting the tailwheel down
with full up-elevator makes for easy taxiing
back to the pits.
GENERAL FLIGHT PERFORMANCE
Stability: Aircraft designed for aerobatics are
not typically designed to be stable; instability
is what allows us to do incredible aerobatic
maneuvers. ;at said, when flown in a normal
pattern, the plane feels fine and flies like a 3D
Tracking: ;e size of the model is deceiving
as it tracks better than predicted. Perhaps
the slightly elongated tail moment and servo
torque power aid this endeavor.
Aerobatics: ;is is where the collaboration
among one of the best pilots, best aircraft
companies, and best model manufacturers
really shows itself o;. ;e roll rate spins like
a drill, and the rifle rolls are blinding. Any
maneuver is possible—dream it and you can
Glide and stall performance: Flying poststall in
high alpha is more proof of how well this plane
is designed. ;e thick wingtip airfoil keeps
wing rock at bay. Glides aren’t like a trainer, but
they’re not too steep; the controls will retain
their e;ectiveness, so just keep a little power
on to extend your slip.
;ere was some coupling in knife-edge, and
the building instructions give you good mix
values to start with. You should also know
that the control surfaces are extremely
powerful even on low rates. ;ere is an option
to increase the throws (outlined in the manual)
to a “professionals-only” level and is how the
estimated rate of three-plus rolls per second
was achieved during the flight tests.
