Servo Travel
It may be the case that all swash-plate servos do not travel the same distance at maximum deflection.
Even small differences between the 3 servos can prevent the swash-plate from being level during coll-
ective pitch inputs and cause the heli to drift.
In order to correct such servo travel differences, you must increase or decrease the servo travel setting
accordingly. Use the menu ATV for adjusting the end points, if necessary. Do not get this menu mixed
up with Dual/Rate. (Dual/Rate menu allows using multiple servo travel ranges and toggling between
them during flight.)
Example:
If during maximum pitch the elevator servo travel is slightly smaller than travel of the two aileron servos,
then the swash-plate will be tilted backwards, causing the heli also to drift backwards. In this case you
should increase the travel of the elevator servo.

Setting Pitch Values
Please choose from two different pitch settings, depending on your flying style. The two settings are
illustrated below. The standard range is for beginners and for pilots who will do some aerobatic flight
without extended periods of inverted flight.
The final pitch values must be tested during test flying. Once set, the values will work with the rotor
blades you used. In case you change over to a different set of rotor blades, the pitch values will have to
be adjusted to the properties (size, profile etc.) of the new set.

If you are an experienced pilot and plan on flying inverted, select the 3D settings:
For setting the respective pitch values, please use a pitch gauge. The values for minimum and maximum
can be specified in the menus of the transmitter.
Minimum Pitch Maximum Pitch 0° - Pitch
Application Low Pitch Hovering (Stick Centered) High Pitch
Standard – 3º 7º to 8º 11º to 12º
Application Low Pitch Stick Centered High. Pitch
3D – 10º bis – 12º 0º 11º to 12º
Pitch Values
The center position of the sticks in your R/C radio corresponds to 0° pitch of the rotor blades. At 0°
pitch, all levers (servo arms, washout lever, mixing arms) should be in horizontal position. At 0° pitch,
the swashplate is in center position, allowing the same travel in upward (positive pitch) and downward
(negative pitch) direction. This setting results in a linear pitch curve, which is ideal for 3D-style flying.
Pilots who wish to fly with less negative pitch should reduce the pitch curve to approx. -3° pitch. Note
that with this latter set-up the sticks are not at center position for hovering.
