Specifications

If your tail servo is fast (<0.11 sec/60 degrees) set this to a lower value.
If your tail servo is slower or you are using a fixed pitch tail driven by a variable speed motor
(Piccolo Hummingbird, etc.) then set the DELAY to a higher value.
13.5.4.2.4. Setting LIMIT
This controls the amount of tail servo travel.
1. Turn on the transmitter.
2. Disconnect the heli motor.
3. Plug in the heli battery.
4. Wait for the gyro to initialize.
5. After the gyro has initialized, make sure the tail servo is at the center of its travel range (90
degrees to servo body) and the tail pitch lever is at the center of its travel range as well
(90 degrees to tail boom).
6. Turn off the AVCS mode temporarily at the transmitter.
7. Use the rudder stick and give full left rudder and full right rudder. The tail servo should be
moving moving the tail pitch slider through its full range of motion.
8. If the tail pitch slider is not moving far enough, then you will need to increase the LIMIT
control.
9. If the tail pitch slider is moving too far and hitting the ends of travel and the tail servo is
emitting buzzing sounds, then decrease the LIMIT control.
10. It may be necessary to move the tail servo mount on the tail boom or adjust a ball link or
something else to ensure that:
i. The tail servo can move the tail rotor pitch from minimum to maximum without binding
(e.g. without the tail servo making a buzzing sound).
ii. The tail servo should be centered when the tail rotor pitch is at the middle of its range.
Be sure to reenable AVCS mode after setting the LIMIT control.
13.5.4.2.5. Setting SENSITIVITY
This is set at the transmitter on channel 5 for both Futaba/Hitec and JR radios.
If you have a transmitter with gyro support, then one of the transmitter toggle switches will
switch between two gyro sensitivity settings, and there will be a menu where you can choose
the two gyro settings associated with the two switch positions. In this case, set the down switch
setting to 50% normal (yaw-rate) mode and the up switch position to 50% heading hold mode.
If you do not have a transmitter with built-in gyro support, then you will use the landing gear
channel to control the gyro sensitivity. The two gear positions (up/down) will be used to select
two gyro sensitivity settings.
If you have a Futaba/Hitec (negative shift) radio without gyro support, then channel 5 settings
below 50% are non-heading hold mode sensitivity and settings above 50% are heading-hold
mode sensitivity. For the initial settings, set the down switch position to 25% travel and the up
switch position to 75% travel.
