Position 1 = normal: Used for startup, take-off, landing, and typical fl ight profi les.
Position 2 = idle-up 1: Used for aerobatic fl ight
Position 3 = idle-up 2: Typically used as a secondary setup for aerobatic fl ight.
Make sure all mechanical linkages are connected exactly as specifi ed in the helicopter’s instruction manual.
Make sure the model’s full throttle position can be achieved when the throttle stick is at maximum defl ection.
The throttle trim must be able to minimize throttle control completely when the throttle limiter is at idle position.
Follow all other instructions for THROTTLE CURVE as explained on page 14.
THROTTLE HOLD
Throttle hold allows full use of collective pitch while setting the throttle at a user pre-determined position.
This function is often used for autorotation. The pilot can then release the hold and regain full control of
the throttle as needed.
With the cursor over “Position”, set a percent of full throttle that the throttle channel will defl ect to automatically
when the control switch is moved to the ON position.
The CTRL line is for setting the ability to turn this function ON/OFF with a switch. Selecting “INH” inhibits
this function from operating. With the cursor next to CTRL, defl ect the switch that will control throttle hold.
In one position the control will be ON. Moving the switch to the opposition will turn the control OFF.
To enable the PITCH CURVE HOLD function described below, select “ACT” on the “PITCH CRV” line.
Otherwise leave at “INH”.
PITCH CURVE
The method for setting the blade collective pitch curve is the same as for the throttle curve as explained
above, by moving the throttle stick and using the same controls within the pitch curve screen. This works
in conjunction with the throttle curve for optimum vertical movement of the helicopter. Separate curves can
be set for normal, idle-up 1, and idle-up 2.
PITCH CURVE HOLD
The setting method is the same as for throttle and pitch curve.
SWASHPLATE RING
Depending on how certain mixes are set and mechanical linkages are connected to the swash plate, it’s
possible that the mechanical connections can accidentally be damaged or dislodged if they are forced to
try and move past their own limitations. By adjusting the maximum amount of travel the aileron and elevator
channels can move the controls away from center, this SWASHPLATE RING function can help prevent
damage from occuring to controls inside the model. At the default 150% setting the controls are not limited,
and effectively turns this function off.
Once inside this screen, press ENTER to highlight the “Rate” value. Press or to fi nd the desired
maximum rate. The circle graphic represents the maximum movement rate. Moving the aileron and/or elevator
stick to their limits will cause the actual position of the these controls to show at the bottom of the screen.
THROTTLE MIXER
This mix is used for non-heading hold gyros or when a heading hold gyro is in normal mode. The helicopter’s
throttle channel can be mixed to the tail (rudder) channel. This mix can remain active at all times, or be
controlled by selecting a switch on the CTRL line. Move the cursor to select the rate to adjust, press ENTER
and then
or to adjust the value. To reset any mix value or clear a switch selection, move the cursor
to the value, press ENTER, and then press CLEAR.
