A 7-channel or greater computer radio is highly recommended
for the Hangar 9 1/3-Scale Sukhoi SU-31. This allows the
following features:
• Mixing the right aileron to the left aileron
(flapperon mix)
• Electronically adjustable aileron differential
• Mixing the right elevator to the left elevator
(dual elevator mixing)
• Independent travel and trim adjustments of
each elevator half
• Mixing the right rudder servo to the left rudder servo
• Rudder to elevator mixing to correct rudder to
elevator coupling
• Rudder to aileron mixing to correct rudder to
aileron coupling
When using a 7-channel or greater computer radio, each servo
is plugged into its own separate channel. Consult your radio
manual for specific details on hookup and programming. If using
a 6-channel radio with flapperon mix, the aileron servos are each
plugged into their own channels. The right aileron servo plug
into the aileron socket in the receiver, while the left aileron servo
plug into channel 6. With flapperon activated in the programming,
this allows for independent travel adjustment of each aileron in
each direction and electronic aileron differential. Consult your
manual for more programming details. With a 6-channel computer
radio, it will be necessary to Y-harness the two rudder and elevator
servos; a reversed elevator servo is needed to achieve the correct
control direction or a reversed servo can be used here. Special
attention must be taken with the rudder servos so that they don’t
fight each other throughout the rudder travel. This is caused by
non-symmetrical pushrod geometry right to left. It may be
necessary to rotate the arm on the servo one or two splines
(most of the time toward the rear) and readjust the linkage
length in order to prevent binding.
Using a non-computer radio will require that the aileron, elevator,
and rudder be Y-harnessed. Be sure to use a reversed servo for
one of the elevator servos. Again, special attention must be taken
with the rudder servos so that they don’t fight each other
throughout the rudder travel. This is caused by non-symmetrical
pushrod geometry right to left. It may be necessary to rotate the
arm on the servo one or two splines (most of the time toward the
rear) and readjust the linkage length in order to prevent binding.
If you’ve ever thought about purchasing a computer radio, now
is a good time to do it!
Section 14: Balancing the Model
Section 15: Radio Setup
Correctly balancing an aerobatic model is critical to its performance
and flight characteristics. The recommended Center of Gravity
(CG) for the Hangar 9
® 1/3-Scale Sukhoi Su-31 is at the center
of the wing tube opening at the fuselage sides. There is a range of
1
/
2
" forward and
1
/
2
" rearward from the center of the wing tube. It
may be necessary to move batteries and radio equipment to
achieve the correct balance on your Sukhoi. Do this first before
adding any weight to the aircraft.
