Helicopter Setup Instructions
ST1: ON, when Flt. Mode Switch centered
ST2: ON when Flt. Mode Switch is forward.
ST3: ON when Flt. Cond Switch is forward.
As these functions are switched on or off, ST3 will
override all the others, followed by ST2 and ST1, which
will override NOR. Regular settings (NOR) occur when
the others are off. Dual rates, exponentials, throttle and
pitch curves, revolution mixing, and gyro gain may be
independently selected for each condition. Here are
some suggested starting settings if your instructions do
not provide any:
Throttle Curve ST1
Throttle Curve ST2
Pitch Curve ST1
Pitch Curve ST2
Pitch Curve ST3 (HOLD)
18. Throttle Curve. You
can use the Throttle Curve
(THCV) menu’s five-point
setting curves to fine-tune
the engine servo’s response.
Adjust the throttle position
for hover to get the desired head RPM. You can change
the curve values to make a steeper curve near idle and
shallower curve past hover. See the THCV menu description
on page 58 for more details.
If your instructions don’t give any suggested values,
you may start with the following settings:
Throttle Curve NOR
Point 1 (low) 2 3 4 5 (high)
% 0 26 45 72 100
Point 1 (low) 2 3 4 5 (high)
% 0 +5 +6.5 80 +10.0
19. Pitch Curve. You can
use the Pitch Curve(PTCV)
menu’s five-point setting
curves to make finer adjust-
ments
to the endpoints and
the middle of travel of the pitch servo. Your model’s
instructions may provide suggested values for the blade
pitch angles. If not, you may want to start with the
following:
Pitch Curve NOR
20. Revolution mixing
(RVMX) uses the tail rotor to
suppress the torque
reaction of the main rotor due
to changes in collective pitch. It
is disabled whenever Idle-Up or
Throttle Hold are activated.
RVMX may be set on either side of the stick (note the letters
R/D and L/U displayed). Adjust RVMX mixing for both travel di-
rections as described in the trimming instructions on page 62.
21. Gyro settings. You can
select an independent value
of gyro gain for each flight
condition by using the GYRO
menu. Select the desired
flight condition, then use the
Data keys to choose the
desired value. The gyro must be plugged into CH6. This
function will only work with dual rate heading hold gyros.
22. Aerobatic Setups and Flight Conditions. Your
Eclipse 7 Pro system has three built-in flight condition menus
in addition to the normal (NOR) hovering mode.
Two -- ST1 and ST2 -- are typically used for aerobatics,
including 540 stall turns, looping, and rolling stall turns.
ST3 is used for “throttle hold” so that the throttle servo is
disengaged during autorotation. These functions are
switched on as follows:
NOR: ON when Flt. Mode Switch is back.
Point 1 (low) 2 3 4 5 (high)
% 50 38 50 75 100
Point 1 (low) 2 3 4 5 (high)
% 100 50 38 50 100
Point 1 (low) 2 3 4 5 (high)
% -4 deg +0.5 +6.0 +7.5 +9.0
Point 1 (low) 2 3 4 5 (high)
% -4 deg -- +6.5 -- +12
Point 1 (low) 2 3 4 5 (high)
% -9 deg - 6.0 0 6.0 9 or 10.0
23. Throttle Hold Setting.
Throttle hold (HOLD)
commands the throttle to
a preset position near idle
and disconnects it from
pitch when activated. Move to
the HOLD menu and
move the Flt. Cond. switch forward position. Set the
hold position to maintain engine speed safely above idle
without engaging the main rotor clutch.
24. Dual Rate Settings.
If you find that your aileron
and elevator controls are
too sensitive, you may set
dual rates to reduce them.
Use the dual rate (D/R) window
to adjust them to the
desired amount of response when the switch is flipped.
This is only a brief introduction to the setup procedure
for helicopters. Be sure to browse through the pages
following this example to see the details about the menus
for helicopters.
