XCLUSIVE UNCTION
(Swash Basic) Rotational equalizer [default: off]
This parameter works to optimize pirouette stability during station-
ary and forward flight. Press the DATA [+] or [-] key to turn the func-
tion on or off.
(Swash Basic) Equalizer direction [default: normal]
This parameter sets the rotational equalizer direction. Setting meth-
od: When the CGY750 is in this mode, the swashplate will tilt on di-
rection and stay that way. Observe the direction of the tilt relative to
the surface on which the model sits. Rotate the model 90 degrees
about its mainshaft clockwise or counterclockwise. The swashplate
should remain tilted in the same direction relative to the surface on
which the model sits. Adjust Equa.Dir from NORMAL to REVERSE
if needed to keep the swashplate tilt in the same direction as the
model is rotated. Correctly setting of the rotational equalizer is criti-
cal for proper flight performance during pirouettes. All linkages from
servos to swashplate should be installed prior to setting direction.
(Flight Tuning) Gyro working mode [default: CMT]
The available choices are CMT, Normal or AVCS. The CMT mode
will allow you to select either AVCS or Normal mode via the trans-
mitter. In Normal mode the gyro will always operate in Normal Rate
Mode, and when AVCS it will always operate in AVCS Mode. Use
the data [+] or [-] key to select the desired working mode.
(Flight Tuning) Aileron gain separation [default: 6pnt ranges:
0~20pnt]
This parameter sets the aileron and elevator of the gyro gain sepa-
ration. 6pnt means the aileron gain is lesser 6 points with elevator
gain. It is useful when the aileron and elevator gain channels are
set to same channel and aileron and elevator gain are adjusted at
the same time. The rationale for this parameters lies in the fact that
most models functionally will tolerate more gyro gain on the eleva-
tor axis than on the aileron axis.
(Flight Tuning) Response style [default: 12n ranges: 1~20n]
[RespSty] tunes the overall heading hold/AVCS effect of the sys-
tem. Values of 8-12 n are compatible with moderate to aggressive
flying styles and are good for most sport/3D flying. NOTE that with
high(er) [RespSty] values, try to ensure that the swashplate is rea-
sonably level prior to spool up.
(
Flight Tuning) Stability gain setting [default: 5
C1
1~10]
Depending on many variables such as model, rotor blade design,
head speed, head dampening, and servo choice, the amount of
transmitter cyclic gyro gain that the model will tolerate without os-
cillation may be lower than the percentage that provides the most
stable flight. If the model is observed to be oscillating or wobbling
at your chosen headspeed with low transmitter cyclic gyro gain
percentages, lowering the Stability.Gn parameter a point or two will
allow for higher cyclic gyro gain without inducing a wobble or oscil-
lation in the model.
(Flight Tuning) High pitch gain [default: 60%
0~100%]
HP.gain (high pitch) sets the cyclic gyro's internal control algorithm
gain with high or low collective pitch inputs. Increasing this param-
eter's percentage results more holding power as collective pitch
is input aggressively during aerobatics, but if its value is tuned too
high, wobble or oscillation may occur.
(Rudder Basic) Flight mode [default: 3D]
Selects the flight mode. Always try the "Sports" flight mode first
and if you determine that the feel is not aggressive enough or if
the pirouette rate is not fast enough then try the "3D" flight mode.
The "Sports" Flight Mode will satisfy most pilots.The flight mode is
changed by pushing the data [+] or [–] key.
(Governor Basic) Battery failsafe setting [default: Inhibit]
The governor goes into the failsafe mode when the battery voltage
is below BFS.Volt. When activated, the governor is deactivated, and
the throttle servo is moved to B/FS position. When the throttle stick
is moved to idle position, the B/FS condition is deactivated for 30
seconds and then returned to B/FS after 30 seconds have passed.
Move the throttle stick to B/FS position as desired. Push set key to
confirm the setting. Pushing RSET will inhibit the function.

(Governor Basic) Limit point testing
Limit point setting confirms the throttle servo position at idle and full
throttle. Push data + or – key. Throttle servo moves to the setting
point indicated on the display.
(Governor Basic) Response [default: Middle]
This parameter selects the governor operation response. Select
the best match for your engine type. Pushing data+ or – key, the
mode is changed. Recommended selection are, Middle → glow
engine, Moderate → gasoline engine, Quick → brushless motor,
Silent → electric models when RPM detection is accomplished
either with a magnet on the motor's rotor or with a brushless phase
sensor.
(S.BUS Basic) S.BUS setting: AIL gain channel [default: 9ch]
Using the data [+] or [-] keys to set the correct channel number.
(S.BUS Basic) S.BUS setting: ELE gain channel [default:
10ch]
Using the data [+] or [-] keys to set the correct channel number.
(Governor Expert) Throttle data mode [default: Optimize]
This parameter selects the throttle input operation. Pushing data+
or – key, the mode is changed.

(Governor Expert) Governor ON revolution setting [default:
60%] [ranges: 50% ~ 90%]
This parameter tells the governor at what percentage of the set
rpm it is to become active. The default value is 60 %. In this case,
the governor will not engage until the engine rpm reaches 60 % of
the set rpm. If you feel that the time for governor engagement is
too slow, decrease the value to 50 ~ 55%. The starting time will be
faster.
(Governor Expert) Battery F/S voltage setting [default: 3.8V]
[ranges: 3.5V ~ 7.5V ]
This parameter sets the battery fail safe and low battery alarm volt-
age. Set the proper voltage by the battery type. The battery charac-
teristics are different depending on cell type/chemistry. The voltage
setting is changed by pushing DATA+ or – key. Suggested setting
voltages are as follows.
• 4 cells NiCd or NiMH (Normal: 4.8v) = 3.8 v
• 2 cells LiFe (Normal: 6.6 v) = 6.0 ~ 6.2 v
• 2 cells LiPo (Normal: 7.4 v) = 7.2 ~ 7.4 v
(
Rudder Expert) Gyro basic gain [default: 100%] [ranges: 50%
~ 120%]
This parameter sets the base gain of the gyro. This can be used to
adjust the gain % if your actual transmitter gain does not match the
gain on the CGY750 correctly.
